Text Block [Abstract]
Organization	(1) Organization The WisdomTree Continuous Commodity Index Fund (the “Fund”) and the WisdomTree Continuous Commodity Index Master Fund (the “Master Fund” and together with the Fund, the “Funds”) are commodity pools that were organized as Delaware statutory trusts on October 27, 2006. For each of the Funds, WisdomTree Commodity Services, LLC serves as the commodity pool operator and managing owner (the “Managing Owner”), and GreenHaven Advisors LLC serves as the commodity trading advisor (the “Sub-Adviser”). Shares representing units of fractional undivided beneficial interest in and ownership of the Fund (“Limited Units” or “Shares”) are listed on the NYSE Arca under the symbol “GCC.” Upon inception of the Fund, 50 general units of the Fund (“General Units” or “General Shares”) were issued to the Managing Owner in exchange for a capital contribution of $1,500. We refer to the General Shares and Shares collectively as “Total Shares,” and the holders of the Shares as the “Shareholders.” The Master Fund is wholly-owned by the Fund and the Managing Owner. The Fund holds no investment assets other than the Master Fund’s common units of beneficial interest (“Master Fund Units”). Each Share issued by the Fund correlates to a Master Fund Unit held by the Fund. The Fund and Master Fund commenced investment operations on January 23, 2008, with the offering of 350,000 Shares in exchange for $10,500,000. The Fund commenced trading on the American Stock Exchange (now known as the NYSE Arca) on January 24, 2008 under the symbol “GCC.” The term of the Fund is perpetual, unless terminated earlier in certain circumstances as defined in the Trust Agreements (as defined in Note 2 – Service Providers and Related Party Agreements The Funds’ collective investment objective is to provide investors with exposure to the daily change in the price of a portfolio of commodities (the “Index Commodities”) comprising the Thomson Reuters Continuous Commodity Index, also known as the Continuous Commodity Total Return Index or Equal Weight Continuous Commodity Total Return Index (the “Index”), before the Funds’ expenses. The Index Commodities consist of corn, soybean, wheat, live cattle, lean hogs, gold, silver, copper, cocoa, coffee, sugar, cotton, soybean oil, platinum, crude oil, NY Harbor ULSD (formerly known as heating oil) and natural gas. Thomson Reuters (Markets) LLC, formerly Thomson Reuters America LLC (the “Index Sponsor”), is the owner, publisher and calculation agent of the Index. The Index Sponsor is not an affiliate of the Funds or the Managing Owner. The Fund pursues its investment objective by investing substantially all of its assets in the Master Fund. The Master Fund pursues its investment objective by actively trading exchange traded futures (“Commodity Futures”) on the Index Commodities, with a view to tracking the performance of the Index over time, regardless of whether the Index is rising, falling or flat over any particular period. The Master Fund’s portfolio (its “Portfolio”) also includes cash, U.S. Treasury obligations and other high credit-quality, short-term fixed income securities (collectively, “U.S. Treasuries”) for deposit with the Commodity Broker (as defined below) as margin or otherwise held to cover the Master Fund’s notional exposure to Commodity Futures. The Fund continuously offers and redeems baskets of 50,000 Shares (“Baskets”) to authorized participants (“Authorized Participants”) at a price based on the Master Fund’s Net Asset Value (as defined in Note 7 – Share Creations and Redemptions) The Managing Owner and the Shareholders share in any profits and losses attributable to the Fund in proportion to the percentage interest owned by each. The Managing Owner and the Funds retain the services of third party service providers for the ongoing operations of the Funds. See Note 2 – Service Providers and Related Party Agreements

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(3) Summary of Significant Accounting Policies (a) Basis of Presentation and Consolidation The financial statements of the Fund and the Master Fund have been prepared using U.S. generally accepted accounting principles (“GAAP”). The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative GAAP recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under the authority of federal laws are also sources of authoritative GAAP for SEC registrants. In accordance with Accounting Standards Update (‘‘ASU’’) 2013-08, All of the capital raised by the Fund from the offering of its Shares is used to purchase Master Fund Units. The financial statements of the Fund include the balances of the Master Fund on a consolidated basis and all inter-company balances and transactions have been eliminated in the consolidation. Separate financial statements of the Master Fund are presented to comply with reporting requirements of the SEC as both the Fund and the Master Fund are SEC registrants. (b) Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Managing Owner to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the amounts of reported income and expenses during the period. Actual results could differ from those estimates. (c) Cash Held by Broker A portion of the Master Fund’s cash is held by the Commodity Broker and is applied towards the daily variation margin movements on the Master Fund’s open Commodity Futures. The Commodity Broker allows the Master Fund to apply its U.S. Treasuries positions towards its initial margin requirement for the Master Fund’s futures positions, hence all cash held by broker is unrestricted cash. The cash and U.S. Treasuries positions are held in segregated accounts at the Commodity Broker and are not insured by the Federal Deposit Insurance Corporation. (d) U. S. Treasury Obligations The Master Fund records purchases and sales of U.S. Treasuries on a trade date basis. These holdings are marked to market based on quotations from broker-dealers or independent service providers. The Master Fund may hold U.S. Treasuries for deposit with the Commodity Broker as margin for trading and holding against initial margin of the open Commodity Futures. Interest income is recognized on an accrual basis when earned. Premiums and discounts are amortized or accreted over the life of the U.S. Treasuries. (e) Futures Contracts The Master Fund utilizes futures contracts to obtain long exposure to Commodity Futures consistent with its investment objective. These contracts are recorded on a trade date basis and open contracts are valued daily at settlement prices provided by the relevant exchanges. In the Schedules of Investments, Commodity Futures are presented at their published settlement prices on the last business day of the period, in accordance with the fair value accounting standard. Since these contracts are actively traded in markets that are directly observable and which provide readily available price quotes, their market value is deemed to be their fair value under the fair value accounting standard. See Note 4 – Fair Value Measurements (f) Income Taxes The Fund and Master Fund are treated as partnerships for U.S. federal income tax purposes. Accordingly, the Fund and Master Fund are not subject to U.S. federal income tax and may not be subject to state or local income taxes. As a result, no provision for federal, state or local income taxes has been made in the accompanying consolidated financial statements, as investors are individually liable for income taxes, if any, on their allocable share of the Fund’s income, gain, loss, deductions and other items. The Fund accounts for uncertainty in income taxes pursuant to the applicable accounting standard, which provides measurement, presentation and disclosure guidance related to uncertain tax positions. The guidance addresses how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under this topic, the Fund may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. (g) Subsequent Events For purposes of disclosure in the consolidated financial statements, the Funds have evaluated events occurring between the period ended December 31, 2019 and when the financial statements were issued on February 21 During that period, no Shares were created and 550,000 Shares were redeemed for $10,139,270, resulting in 6,250,050 Total Shares outstanding. Other than these events, the evaluation did not result in any subsequent events that necessitated disclosures and/or adjustments.

Fair Value Disclosures [Abstract]
Fair Value Measurements	(4) Fair Value Measurements The existing guidance for fair value measurements establishes the authoritative definition for fair value, sets out a framework for measuring fair value and outlines the required disclosures regarding fair value measurements. Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The Master Fund uses a three-tier fair value hierarchy based upon observable and unobservable inputs as follows: Level 1 – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2 – Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 – Unobservable inputs for the asset or liability. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The assets of the Master Fund are either exchange-traded securities that are valued at the official closing price on the exchange where they are principally traded or U.S. government securities that are valued using dealer and broker quotations or other inputs that are observable or can be corroborated by observable market data. A summary of the Master Fund’s assets and liabilities at fair value as of December 31, 2019, classified according to the levels used to value them, is as follows: Assets Quoted Other Significant Totals U.S. Treasury Obligations $ — $ 115,831,172 $ — $ 115,831,172 Unrealized appreciation on futures contracts 6,162,155 — — 6,162,155 Total $ 6,162,155 $ 115,831,172 $ — $ 121,993,327 The Master Fund did not hold any Level 3 securities during the year ended December 31, 2019.

Investments, All Other Investments [Abstract]
Financial Instrument Risk	(6) Financial Instrument Risk In the normal course of its business, the Master Fund may be party to financial instruments with off-balance “off-balance Market risk is the potential for changes in the value of the financial instruments traded by the Master Fund due to market changes, including fluctuations in commodity prices. In entering into these contracts, there exists a market risk that such contracts may be significantly influenced by conditions, resulting in such contracts being less valuable. If the markets should move against all of the futures interest positions at the same time, and the Managing Owner is unable to offset such positions, the Master Fund could experience substantial losses. Credit risk is the possibility that a loss may occur due to the failure of an exchange clearinghouse to perform according to the terms of a contract. Credit risk with respect to exchange-traded instruments is reduced to the extent that an exchange or clearing organization acts as counterparty to the transactions. The Master Fund’s risk of loss in the event of counterparty default is typically limited to the amounts recognized in the Statement of Financial Condition and not represented by the contract or notional amounts of the instruments. The Fund and the Master Fund have not utilized, nor do they expect to utilize in the future, special purpose entities to facilitate off-balance off-balance

Accounting Policies [Abstract]
Basis of Presentation and Consolidation	(a) Basis of Presentation and Consolidation The financial statements of the Fund and the Master Fund have been prepared using U.S. generally accepted accounting principles (“GAAP”). The Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) is the exclusive reference of authoritative GAAP recognized by the FASB to be applied by nongovernmental entities. Rules and interpretive releases of the Securities and Exchange Commission (“SEC”) under the authority of federal laws are also sources of authoritative GAAP for SEC registrants. In accordance with Accounting Standards Update (‘‘ASU’’) 2013-08, All of the capital raised by the Fund from the offering of its Shares is used to purchase Master Fund Units. The financial statements of the Fund include the balances of the Master Fund on a consolidated basis and all inter-company balances and transactions have been eliminated in the consolidation. Separate financial statements of the Master Fund are presented to comply with reporting requirements of the SEC as both the Fund and the Master Fund are SEC registrants.
Use of Estimates	(b) Use of Estimates The preparation of the financial statements in conformity with GAAP requires the Managing Owner to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the amounts of reported income and expenses during the period. Actual results could differ from those estimates.
Cash Held by Broker	(c) Cash Held by Broker A portion of the Master Fund’s cash is held by the Commodity Broker and is applied towards the daily variation margin movements on the Master Fund’s open Commodity Futures. The Commodity Broker allows the Master Fund to apply its U.S. Treasuries positions towards its initial margin requirement for the Master Fund’s futures positions, hence all cash held by broker is unrestricted cash. The cash and U.S. Treasuries positions are held in segregated accounts at the Commodity Broker and are not insured by the Federal Deposit Insurance Corporation.
U. S. Treasury Obligations	(d) U. S. Treasury Obligations The Master Fund records purchases and sales of U.S. Treasuries on a trade date basis. These holdings are marked to market based on quotations from broker-dealers or independent service providers. The Master Fund may hold U.S. Treasuries for deposit with the Commodity Broker as margin for trading and holding against initial margin of the open Commodity Futures. Interest income is recognized on an accrual basis when earned. Premiums and discounts are amortized or accreted over the life of the U.S. Treasuries.
Futures Contracts	(e) Futures Contracts The Master Fund utilizes futures contracts to obtain long exposure to Commodity Futures consistent with its investment objective. These contracts are recorded on a trade date basis and open contracts are valued daily at settlement prices provided by the relevant exchanges. In the Schedules of Investments, Commodity Futures are presented at their published settlement prices on the last business day of the period, in accordance with the fair value accounting standard. Since these contracts are actively traded in markets that are directly observable and which provide readily available price quotes, their market value is deemed to be their fair value under the fair value accounting standard. See Note 4 – Fair Value Measurements
Income Taxes	(f) Income Taxes The Fund and Master Fund are treated as partnerships for U.S. federal income tax purposes. Accordingly, the Fund and Master Fund are not subject to U.S. federal income tax and may not be subject to state or local income taxes. As a result, no provision for federal, state or local income taxes has been made in the accompanying consolidated financial statements, as investors are individually liable for income taxes, if any, on their allocable share of the Fund’s income, gain, loss, deductions and other items. The Fund accounts for uncertainty in income taxes pursuant to the applicable accounting standard, which provides measurement, presentation and disclosure guidance related to uncertain tax positions. The guidance addresses how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under this topic, the Fund may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution.
Subsequent Events	(g) Subsequent Events For purposes of disclosure in the consolidated financial statements, the Funds have evaluated events occurring between the period ended December 31, 2019 and when the financial statements were issued on February 21 During that period, no Shares were created and 550,000 Shares were redeemed for $10,139,270, resulting in 6,250,050 Total Shares outstanding.
