Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund is actively managed and seeks to provide risk-managed exposure to the SPDR S&P 500 ETF Trust (SPY). The Fund seeks to provide an alternative to managing and evaluating a series of buffer strategies, seeking to provide the upside of the SPY while mitigating downside losses with 9% or 15% built-in buffers. Through the Options Portfolio, the Fund will seek to participate in the price return of the SPY, subject to investment gains up to a limit, and provide protection against SPY losses up to a limit. The Sub-Adviser will actively monitor the performance of the Options Portfolio and, if certain criteria are met, rebalance or “step-up” the portfolio to protect capital or capture portfolio gains experienced by the Fund, depending on its evaluation of market conditions. During the 12 months ended October 31, 2024, gains were largely driven by tech and the market interest in AI, coupled with the expectation of a possible soft landing. Market breadth widened in the latter half of the time period, but remained fairly narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Nasdaq-100 Index posted strong positive performance for the year ended October 31, 2024. The technology sector maintained its momentum, supported by ongoing investor enthusiasm for AI and the enduring leadership of the “Magnificent 7.” However, as the period progressed, market dynamics began to favor value-oriented names over the growth-focused companies that dominate the Nasdaq-100, leading to a modest rotation while the index still delivered solid gains overall. Over this same period, LOUP outperformed the Nasdaq-100, largely attributable to its allocations to industrials and its security selection within large caps.

IBD® 50 is Investor’s Business Daily’s signature investing tool—targeting companies that are generating outstanding profit growth, big sales increases, wide profit margins and a high return on equity. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall. FFTY delivered a strong positive return over the same period, but trailed the S&P 500, largely attributable to its allocation to financials and midcaps.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to provide investors with returns of the MerQube U.S. Large Cap Equity Buffer Laddered Index. The Index is comprised of the shares of twelve Innovator U.S. Equity Buffer ETFs (Underlying ETFs), the investment in which seeks to provide investors with U.S. large-cap equity market exposure while attempting to limit downside risk through a laddered portfolio of the Underlying ETFs. Under normal market conditions, the Fund will invest substantially all of its assets in the Underlying ETFs, which seek to provide investors with returns that match the price return of the SPDR® S&P 500® ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of its respective Outcome Period. Unlike the Underlying ETFs, the Fund itself does not pursue a defined outcome strategy. The Buffer is only provided by the Underlying ETFs and the Fund itself does not provide any stated Buffer against losses. The S&P 500 Index delivered strong performance during the 12 months ended October 31, 2024. Gains were largely driven by tech and the market interest in AI, coupled with the expectation of a possible soft landing. Market breadth widened in the latter half of the time period, but remained fairly narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to provide investors with returns of the FTSE Laddered Power Buffer Strategy Index (Index). The Index is comprised of the shares of twelve Innovator U.S. Equity Power Buffer ETFs (Underlying ETFs), the investment in which seeks to provide investors with U.S. large-cap equity market exposure while attempting to limit downside risk through a laddered portfolio of the Underlying ETFs. Under normal market conditions, the Fund will invest substantially all of its assets in the Underlying ETFs, which seek to provide investors with returns that match the price return of the SPDR® S&P 500® ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of its respective Outcome Period. Unlike the Underlying ETFs, the Fund itself does not pursue a defined outcome strategy. The Buffer is only provided by the Underlying ETFs and the Fund itself does not provide any stated Buffer against losses. The S&P 500 Index delivered strong performance during the 12 months ended October 31, 2024. Gains were largely driven by tech and the market interest in AI, coupled with the expectation of a possible soft landing. Market breadth widened in the latter half of the time period, but remained fairly narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund is actively managed and seeks to provide risk-managed exposure to the SPDR S&P 500 ETF Trust (SPY). The Fund seeks to provide an alternative to managing and evaluating a series of buffer strategies, seeking to provide the upside of the SPY while mitigating downside losses with 9% or 15% built-in buffers. Through the Options Portfolio, the Fund will seek to participate in the price return of the SPY, subject to investment gains up to a limit, and provide protection against SPY losses up to a limit. The Sub-Adviser will actively monitor the performance of the Options Portfolio and, if certain criteria are met, rebalance or “step-up” the portfolio to protect capital or capture portfolio gains experienced by the Fund, depending on its evaluation of market conditions. During the 12 months ended October 31, 2024, gains were largely driven by tech and the market interest in AI, coupled with the expectation of a possible soft landing. Market breadth widened in the latter half of the time period, but remained fairly narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? EPRF is the only 100% investment grade preferred ETF available. Investment grade preferred stocks tend to have more duration than benchmark preferred stocks because their higher credit quality typically means they are structured as perpetual cash flows (no maturity). During the 12 months ended October 31, 2024, longer-term rates declined and pushed preferred stock prices higher. Preferred stocks were one of the best performing fixed income asset classes, outperforming Treasuries, investment grade, and high yield corporates. Over the time period listed above, EPRF performed mostly in line with preferred stock benchmarks. The risk-on environment did not materially impact EPRF, with its higher credit quality. Even after its recent price rally, the asset class continues to provide attractive yields.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund is actively managed and seeks to provide investors with the potential for rates of return that outperform the price return of the SPDR® S&P 500® ETF Trust (SPY) after achieving performance thresholds. In markets where the S&P 500 Index is down, the Fund is designed to match the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the Fund has potential to outperform the S&P 500 Index during periods where SPY achieves sustained positive performance. The S&P 500 Index delivered strong performance during the 12 months ended October 31, 2024. Gains were largely driven by tech and the market interest in AI, coupled with the expectation of a possible soft landing. Market breadth widened in the latter half of the time period, but remained fairly narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the iShares 20+ Year U.S. Treasury ETF (TLT) up to a stated upside Cap, while limiting downside losses to TLT by the amount of its stated Floor over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the I.C.E US Treasury 20+ Year Index is down, the risk mitigation attributes of the stated Floor provide an opportunity for the Fund to soften market losses during the reporting period and outperform the I.C.E US Treasury 20+ Year Index. Alternatively, in markets where the I.C.E US Treasury 20+ Year Index is appreciating, the risk mitigation attributes of the Floor may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Floor will also cause the Fund to experience different returns than TLT. The year ended October 31, 2024, was mixed for 20+ Year Treasuries, reflecting shifts in the rate environment and evolving market expectations. Performance for the period finished moderately positive, with a rally in longer-duration bonds in Q3 2024 driven by signs of easing inflation and softer economic data. However, renewed strength in the economy later in the period, coupled with persistent uncertainty over Federal Reserve policy, led to rising long-term yields, tempering gains and introducing volatility.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the iShares 20+ Year U.S. Treasury ETF (TLT) up to a stated upside Cap, while limiting downside losses to TLT by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the I.C.E US Treasury 20+ Year Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the I.C.E US Treasury 20+ Year Index. Alternatively, in markets where the I.C.E US Treasury 20+ Year Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than TLT.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

The effect of the Cap and the Buffer will also cause the Fund to experience different returns than EEM.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price return of the iShares MSCI Emerging Markets ETF (EEM) up to a stated upside Cap, while limiting downside losses to EEM by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the MSCI Emerging Markets Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the MSCI Emerging Markets Index. Alternatively, in markets where the MSCI Emerging Markets Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than EEM. Supported by improving economic fundamentals across key regions, the MSCI Emerging Markets Index saw moderate growth for the year ended October 31, 2024, Technology stocks continued to perform well, contributing positively to returns, while real estate exposure in emerging markets remained a drag on overall performance.

The Fund seeks to match the price returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period.

The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Expenses [Text Block]	WHAT WERE THE FUND COSTS FOR THE PAST YEAR? * (based on a hypothetical $10,000 investment) Fund Name Costs of a $10,000 investment Costs paid as a percentage of a $10,000 investment Innovator Growth Accelerated ETF-Quarterly $92 0.79%	[37]

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to provide accelerated returns of the Invesco QQQ Trust (QQQ) up to a stated Cap over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the Nasdaq-100 Index is down, the Fund will generally provide similar losses to the Nasdaq-100 Index at the end of the Outcome Period. Alternatively, in markets where the Nasdaq-100 Index is appreciating, the Fund seeks to provide accelerated returns of QQQ, limited by the Fund’s Cap, which limits the amount of potential accelerated Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap may also cause the Fund to experience different returns than QQQ. The Nasdaq-100 Index posted strong positive performance for the year ended October 31, 2024. The technology sector maintained its momentum, supported by ongoing investor enthusiasm for AI and the enduring leadership of the “Magnificent 7.” However, as the period progressed, market dynamics began to favor value-oriented names over the growth-focused companies that dominate the Nasdaq-100, leading to a modest rotation while the index still delivered solid gains overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the Invesco QQQ Trust (QQQ) up to a stated upside Cap, while limiting downside losses to QQQ by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the Nasdaq-100 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the Nasdaq-100 Index. Alternatively, in markets where the Nasdaq-100 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience  different returns than QQQ. The Nasdaq-100 Index posted strong positive performance for the year ended October 31, 2024.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the Invesco QQQ Trust (QQQ) up to a stated upside Cap, while limiting downside losses to QQQ by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the Nasdaq-100 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the Nasdaq-100 Index. Alternatively, in markets where the Nasdaq-100 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience  different returns than QQQ. The Nasdaq-100 Index posted strong positive performance for the year ended October 31, 2024. The technology sector maintained its momentum, supported by ongoing investor enthusiasm for AI and the enduring leadership of the “Magnificent 7.” However, as the period progressed, market dynamics began to favor value-oriented names over the growth-focused companies that dominate the Nasdaq-100, leading to a modest rotation while the index still delivered solid gains overall.

The Fund seeks to match the price return of the iShares MSCI EAFE ETF (EFA) up to a stated upside Cap, while limiting downside losses to EFA by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the MSCI EAFE Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the MSCI EAFE Index. Alternatively, in markets where the MSCI EAFE Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than EFA. The MSCI EAFE Index delivered strong performance for the year ended October 31, 2024. Gains were supported by a stabilization in global economic activity and resilient corporate earnings, particularly in developed markets outside the U.S. However, rising geopolitical tensions and persistent monetary policy tightening in several regions introduced periods of heightened volatility. During Q3 2024, easing inflation concerns and improved investor sentiment bolstered returns, though these gains were tempered later in the period by renewed concerns over a potential economic slowdown in the Eurozone and mixed economic data. Overall, the MSCI EAFE Index demonstrated resilience in navigating a challenging macroeconomic environment.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price return of the iShares MSCI EAFE ETF (EFA) up to a stated upside Cap, while limiting downside losses to EFA by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the MSCI EAFE Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the MSCI EAFE Index. Alternatively, in markets where the MSCI EAFE Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than EFA. The MSCI EAFE Index delivered strong performance for the year ended October 31, 2024. Gains were supported by a stabilization in global economic activity and resilient corporate earnings, particularly in developed markets outside the U.S. However, rising geopolitical tensions and persistent monetary policy tightening in several regions introduced periods of heightened volatility. During Q3 2024, easing inflation concerns and improved investor sentiment bolstered returns, though these gains were tempered later in the period by renewed concerns over a potential economic slowdown in the Eurozone and mixed economic data. Overall, the MSCI EAFE Index demonstrated resilience in navigating a challenging macroeconomic environment.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the Invesco QQQ Trust (QQQ) up to a stated upside Cap, while limiting downside losses to QQQ by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the Nasdaq-100 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the Nasdaq-100 Index. Alternatively, in markets where the Nasdaq-100 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience  different returns than QQQ. The Nasdaq-100 Index posted strong positive performance for the year ended October 31, 2024. The technology sector maintained its momentum, supported by ongoing investor enthusiasm for AI and the enduring leadership of the “Magnificent 7.” However, as the period progressed, market dynamics began to favor value-oriented names over the growth-focused companies that dominate the Nasdaq-100, leading to a modest rotation while the index still delivered solid gains overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to provide an income-oriented defined outcome strategy which limits the total return a Fund may provide over the course of the Outcome Period to the Defined Distribution Rate, while potentially limiting downside losses experienced by the S&P 500 Price Return Index (SPX) at the end of the Outcome Period through the implementation of a Barrier. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Barrier provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the structure of the Fund’s investments is such that the Fund will not participate in the upside returns of such index, and the total return provided will be the Fund’s stated Defined Distribution Rate, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Defined Distribution Rate and the Barrier will cause the Fund to experience different returns than SPX. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Expenses [Text Block]	WHAT WERE THE FUND COSTS FOR THE PAST YEAR? * (based on a hypothetical $10,000 investment) Fund Name Costs of a $10,000 investment Costs paid as a percentage of a $10,000 investment Innovator Premium Income 15 Buffer ETF - January $67 0.79%	[69]

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to provide an income-oriented defined outcome strategy which limits the total return a Fund may provide over the course of the Outcome Period to the Defined Distribution Rate, while potentially limiting downside losses experienced by the SPDR S&P 500 ETF Trust (SPY) at the end of the Outcome Period through the implementation of a Buffer. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the structure of the Fund’s investments is such that the Fund will not participate in the upside returns of such index, and the total return provided will be the Fund’s stated Defined Distribution Rate, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Defined Distribution Rate and the Buffer will cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to provide an income-oriented defined outcome strategy which limits the total return a Fund may provide over the course of the Outcome Period to the Defined Distribution Rate, while potentially limiting downside losses experienced by the S&P 500 Price Return Index (SPX) at the end of the Outcome Period through the implementation of a Barrier. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Barrier provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the structure of the Fund’s investments is such that the Fund will not participate in the upside returns of such index, and the total return provided will be the Fund’s stated Defined Distribution Rate, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Defined Distribution Rate and the Barrier will cause the Fund to experience different returns than SPX. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to provide an income-oriented defined outcome strategy which limits the total return a Fund may provide over the course of the Outcome Period to the Defined Distribution Rate, while potentially limiting downside losses experienced by the S&P 500 Price Return Index (SPX) at the end of the Outcome Period through the implementation of a Barrier. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Barrier provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the structure of the Fund’s investments is such that the Fund will not participate in the upside returns of such index, and the total return provided will be the Fund’s stated Defined Distribution Rate, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Defined Distribution Rate and the Barrier will cause the Fund to experience different returns than SPX. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

The Fund seeks to match the price returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Alternatively, in markets where the S&P 500 Index is appreciating, the Fund seeks to provide accelerated returns of SPY, limited by the Fund’s Cap, which limits the amount of potential accelerated Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap may also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to provide accelerated returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated Cap over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund, the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the Fund will generally provide similar losses to the S&P 500 Index at the end of the Outcome Period. Alternatively, in markets where the S&P 500 Index is appreciating, the Fund seeks to provide accelerated returns of SPY, limited by the Fund’s Cap, which limits the amount of potential accelerated Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap may also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Expenses [Text Block]	WHAT WERE THE FUND COSTS FOR THE PAST YEAR? * (based on a hypothetical $10,000 investment) Fund Name Costs of a $10,000 investment Costs paid as a percentage of a $10,000 investment Innovator U.S. Equity Ultra Buffer ETF - July $87 0.79%	[132]

Expense Ratio, Percent	0.79%
Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the SPDR S&P 500 ETF Trust (SPY) up to a stated upside Cap, while limiting downside losses to SPY by the amount of its stated Buffer over the course of the Outcome Period. Because the period contemplated herein does not align with the Outcome Period of the Fund the Fund’s performance stated over the period covered by this report does not reflect the implementation of the Fund’s investment strategy for the full Outcome Period. In markets where the S&P 500 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the S&P 500 Index. Alternatively, in markets where the S&P 500 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than SPY. The S&P 500 Index delivered strong performance for the year ended October 31, 2024. Gains were primarily driven by the continued strength in technology and growing market enthusiasm for artificial intelligence, alongside optimism surrounding a potential soft landing for the economy. While market breadth improved in the latter part of the year, it remained relatively narrow overall.

Factors Affecting Performance [Text Block]	HOW DID THE FUND PERFORM LAST YEAR AND WHAT AFFECTED ITS PERFORMANCE? The Fund seeks to match the price returns of the iShares Russell 2000 ETF (IWM) up to a stated upside Cap, while limiting downside losses to IWM by the amount of its stated Buffer over the course of the Outcome Period.   In markets where the Russell 2000 Index is down, the risk mitigation attributes of the stated Buffer provide an opportunity for the Fund to soften market losses during the reporting period and outperform the Russell 2000 Index. Alternatively, in markets where the Russell 2000 Index is appreciating, the risk mitigation attributes of the Buffer may limit the upside performance over the reporting period by virtue of the Fund’s Cap, which limits the amount of potential Fund gains and represents the absolute maximum return that the Fund can achieve for its Outcome Period. The effect of the Cap and the Buffer will also cause the Fund to experience different returns than IWM. The Russell 2000 Index posted strong returns for the year ended October 31, 2024. Small-cap companies continued to benefit from exceeding earnings growth expectations, alongside improving investor sentiment driven by easing inflationary pressures. However, the index experienced some volatility later in the period as uncertainty surrounding Federal Reserve policy and concerns about economic growth began to weigh on performance.
