Accounting Policies [Abstract]
ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 1 - ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES A. General Description of the Partnership Altegris Winton Futures Fund, L.P. (the “Partnership”) was organized as a limited partnership in Colorado in March 1999, and will continue until December 31, 2035, unless sooner terminated as provided for in the Agreement of Limited Partnership (the “Agreement”), as amended and restated from time to time. The Partnership's general partner is Altegris Advisors, L.L.C. (the “General Partner”). The Partnership speculatively trades commodity futures contracts, options on futures contracts, forward contracts and other commodity interests. The objective of the Partnership’s business is appreciation of its assets. The Partnership is subject to the regulations of the Commodity Futures Trading Commission (the “CFTC”), an agency of the United States (“U.S.”) government that regulates most aspects of the commodity futures industry; rules of the National Futures Association, an industry self-regulatory organization; and the requirements of commodity exchanges and futures commission merchants (brokers) through which the Partnership trades. B. Method of Reporting The Partnership’s financial statements are presented in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Therefore, the Partnership follows the accounting and reporting guidelines for investment companies. The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported fair value of assets and liabilities, disclosures of contingent assets and liabilities as of December 31, 2018 and 2017 and reported amounts of income and expenses for the years ended December 31, 2018, 2017 and 2016. Management believes that the estimates utilized in preparing the Partnership’s financial statements are reasonable; however, actual results could differ from these estimates and it is reasonably possible that differences could be material. C. Fair Value In accordance with the authoritative guidance under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the “exit price”) in an orderly transaction between market participants at the measurement date. In determining fair value, the Partnership uses various valuation approaches. The authoritative guidance under U.S. GAAP establishes a fair value hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are those that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Partnership. Unobservable inputs reflect the Partnership’s assumption about the inputs market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The fair value hierarchy is categorized into three levels based on the inputs as follows: Level 1 - Unadjusted quoted prices in active markets for identical, unrestricted assets or liabilities that the Partnership has the ability to access at the measurement date; Level 2 - Quoted prices which are not active, or inputs that are observable (either directly or indirectly) for substantially the full term of the asset or liability; and Level 3 - Prices, inputs or exotic modeling techniques which are both significant to the fair value measurement and unobservable (supported by little or no market activity). The availability of valuation techniques and observable inputs can vary from assets and liabilities and is affected by a wide variety of factors, including the type of asset or liability, whether the asset or liability is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Those estimated values do not necessarily represent the amounts that may be ultimately realized due to the occurrence of future circumstances that cannot be reasonably determined. Because of the inherent uncertainty of valuation, those estimated values may be materially higher or lower than the values that would have been used had a ready market for the asset or liability existed. Accordingly, the degree of judgment exercised by the Partnership in determining fair value is greatest for assets and liabilities categorized in Level 3. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement falls in its entirety is determined by the lowest level input that is significant to the fair value measurement. Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, the Partnership’s own assumptions are set to reflect those that market participants would use in pricing the asset or liability at the measurement date. The Partnership uses prices and inputs that are current as of the measurement date, including prices and inputs during periods of market dislocation. In periods of market dislocation, the observability of prices and inputs may be reduced for many assets and liabilities. This condition could cause an asset or liability to be reclassified to a lower level within the fair value hierarchy. The Partnership values futures and options on futures contracts at the closing price of the contrac t’s Foreign currency exchange contracts and foreign cross currency exchange contracts are valued at the mean between the bid and ask prices, which approximates fair value. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available. The Partnership includes forward currency contracts in Level 2 of the fair value hierarchy. Where available, the fair value of U.S. government agency bonds and notes is based on quoted prices in active markets. When quoted prices are not available, fair value is determined based on a valuation model that uses inputs that include interest-rate yield curves, cross-currency-basis index spreads, and country credit spreads similar to the bond in terms of issue, maturity and seniority. U.S. government agency bonds and notes are generally categorized in Levels 1 or 2 of the fair value hierarchy. As of December 31, 2018 and 2017, none of the Partnership’s holdings in U.S. government agency bonds and notes were fair valued using valuation models. The fair value of corporate notes is determined using recently executed transactions, market price quotations (where observable), notes spreads or credit default swap spreads. The spread data used are for the same maturity as that of the notes. If the spread data does not reference the issuer, data that references a comparable issuer is used. When observable price quotations are not available, fair value is determined based on cash flow models with yield curves, bond, or single-name credit default swap spreads and recovery rates based on collateral values as key inputs. These valuation methods represent both a market and income approach to fair value measurement. Corporate notes are categorized in Level 2 of the fair value hierarchy; however, in instances where significant inputs are unobservable, they are categorized in Level 3 of the hierarchy. As of December 31, 2018 and 2017, none of the Partnership’s holdings in corporate notes were fair valued using valuation models. The fair value of certificates of deposit is determined based on a constant maturity curve for comparable instruments denominated in USD. This valuation method represents both a market and income approach to fair value measurement. Certificates of deposit are categorized in Level 2 of the fair value hierarchy. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. There were no changes to the Partnership’s valuation methodology during the years ended December 31, 2018 and 2017. The following table presents information about the Partnership’s assets and liabilities measured at fair value as of December 31, 2018 and 2017: December 31, 2018 Level 1 Level 2 Level 3 Balance as of December 31, 2018 Assets: Futures contracts (1)* $ 3,399,238 $ – $ – $ 3,399,238 Forward currency contracts (1) – 331,450 – 331,450 U.S. Government agency bonds and notes – 70,186,759 – 70,186,759 Corporate notes – 40,317,094 – 40,317,094 Certificates of deposit – 6,012,013 – 6,012,013 $ 3,399,238 $ 116,847,316 $ – $ 120,246,554 Liabilities: Futures contracts (1)* $ (5,496,161 ) $ – $ – $ (5,496,161 ) Forward currency contracts (1) – (265,019 ) – (265,019 ) $ (5,496,161 ) $ (265,019 ) $ – $ (5,761,180 ) December 31, 2017 Level 1 Level 2 Level 3 Balance as of December 31, 2017 Assets: Futures contracts (1)* $ 7,042,156 $ – $ – $ 7,042,156 Forward currency contracts (1) – 2,248,858 – 2,248,858 U.S. Government agency bonds and notes – 101,514,933 – 101,514,933 Corporate notes – 51,991,344 – 51,991,344 $ 7,042,156 $ 155,755,135 $ – $ 162,797,291 Liabilities: Futures contracts (1)* $ (3,829,650 ) $ – $ – $ (3,829,650 ) Forward currency contracts (1) – (975,706 ) – (975,706 ) $ (3,829,650 ) $ (975,706 ) $ – $ (4,805,356 ) (1) See Note 7. “Financial Derivative Instruments” for the fair value in each type of contracts within this category. * Futures contracts include settled variation margin. The Partnership’s policy is to recognize any transfers between Level 1 and Level 2 assets as of the Partnership’s fiscal year-end. For the years ended December 31, 2018 and 2017, there were no transfers between Level 1 and Level 2 assets and liabilities. For the years ended December 31, 2018 and 2017, there were no Level 3 securities. D. Investment Transactions and Investment Income Security transactions are recorded on the trade date for financial reporting purposes. Realized gains and losses from security transactions are determined using the specific identification cost method. Change in net unrealized gain or loss from the preceding period is reported in the Statements of Income (Loss). Brokerage commissions and other trading fees are reflected as an adjustment to cost or proceeds at the time of the transaction. Interest income is recorded on an accrual basis. Gains or losses on futures contracts, options on futures contracts and forward currency contracts are realized when contracts are closed. Net unrealized gains or losses on open contracts (the difference between contract trade price and quoted market price) are reflected in the Statements of Financial Condition. Any change in net unrealized gain or loss from the preceding period is reported in the Statements of Income (Loss). Brokerage commissions on futures and options on futures contracts include other trading fees and are recognized as trading gains and losses. Net realized gains and losses from foreign currency related transactions represent gains and losses from sales of foreign currencies, currency gains and losses realized between trade and settlement dates on securities transactions, and the difference between the amounts of interest and foreign withholding taxes recorded on the Partnership’s books and the U.S. Dollar equivalent of the amounts actually received or paid. Net unrealized gain (loss) on other assets and other liabilities denominated in foreign currency arise from changes in the value of assets, other than investments in securities, and liabilities at fiscal year-end, resulting from changes in the exchange rates. J.P. Morgan Chase Bank, N.A. (the “Custodian”) is the Partnership’s custodian. SG Americas Securities, LLC (the “Clearing Broker”) is the Partnership’s commodity broker. A portion of the Partnership’s assets are held as initial margin or option premiums (in cash or Treasury securities) in the Partnership’s brokerage accounts at the Clearing Broker. The Clearing Broker may convert the Partnership’s cash in U.S. dollar to foreign currency to facilitate the Partnership’s commodity trading activities. At times, the Partnership may carry foreign cash on loan with the Clearing Broker. Any net foreign currency on loan will be recognized in Foreign Currency Due to Broker on the Statements of Financial Condition. The Partnership’s Clearing Broker holds margin balances in a single currency, in which all margin requirements can be satisfied in U.S. dollars. Foreign currency balances can also be used to satisfy margin requirements. As of December 31, 2018 and December 31, 2017, the Partnership’s restricted cash balance on the Statements of Financial Condition of $8,266,227 and $16,699,269, respectively, represents the collateral pledged by the Partnership to satisfy the Clearing Broker’s margin requirements in US Dollars. As of December 31, 2018 and December 31, 2017, the Partnership’s restricted foreign currency balance on the Statements of Financial Condition of $637,770 and $2,962,145, respectively, represents the collateral pledged by the Partnership to satisfy the Clearing Broker’s margin requirements in foreign currency. The Partnership’s assets not deposited at the Clearing Broker are deposited with either the Custodian or held in bank cash accounts at Northern Trust Company (and used to pay Partnership operating expenses). For the Partnership’s cash deposited at the Custodian, the Partnership receives cash management services from J.P. Morgan Investment Management Inc. (“JPMIM”). E. Option Contracts Generally, an option is a contract that gives the purchaser of the option, in return for the premium paid, the right to buy a specified security, currency or other instrument (an ‘‘underlying instrument’’) from the writer of the option (in the case of a call option), or to sell a specified security, currency, or other instrument to the writer of the option (in the case of put option) at a designated price. Put and call options that the Partnership may purchase or write may be traded on a national securities exchange or in the over-the-counter (OTC) market. All option positions entered into on a national securities exchange are cleared and guaranteed by the options clearing corporation, thereby reducing the risk of counterparty default. There can be no assurance that a liquid secondary market will exist for any option purchased or sold. As the buyer of an option, the Partnership has a right to buy (call option) or sell (put option) the underlying instrument at the exercise price. The Partnership may enter into closing sale transactions with respect to options, exercise them, or permit them to expire unexercised. When buying options, the potential loss is limited to the cost (premium plus transaction costs) of the option. As the writer of an option, the Partnership has the obligation to buy (call option) or sell (put option) the underlying instrument at the exercise price. When the Partnership writes an option, an amount equal to the premium received by the Partnership is recorded as a liability and subsequently marked to market to reflect the current value of the option written. If the written option expires unexercised, the Partnership realizes a gain in the amount of the premium received. If the Partnership enters into a closing transaction, it recognizes a gain or loss, depending on whether the cost of the purchase is less than or greater than the premium received. If the option is exercised, the Partnership will incur a loss to the extent the difference between the current market value of the underlying instrument and the exercise price exceeds the premium received. As the writer of a call option, the Partnership retains the risk of loss should the underlying instrument increase in value. If the option is exercised, the Partnership will be required to buy or sell the instrument at the exercise price. Accordingly, these transactions result in off-balance sheet risk, as the Partnership’s ultimate obligation may exceed the amount indicated in the Statements of Financial Condition. As of December 31, 2018 and 2017, the Partnership did not hold any option contracts. F. Futures Contracts The Partnership engages in futures contracts as part of its investment strategy. Upon entering into a futures contract, the Partnership is required to deposit with the broker an amount of cash or cash equivalents equal to a certain percentage of the contract amount. This is known as the initial margin. Subsequent payments (“variation margin”) are made or received by the Partnership each day, depending on the daily fluctuations in the value of the contract, and are included in settled variation margin on the Statements of Financial Condition. Due to broker amounts on the Statements of Financial Condition represent the amount of any short fall in the Fund's required cash margin. The Partnership recognizes a realized gain or loss when the contract is closed. There are several risks in connection with the use of futures contracts as an investment option. The change in value of futures contracts primarily corresponds with the value of their underlying instruments. In addition, there is the risk that the Partnership may not be able to enter into a closing transaction because of an illiquid secondary market. Open positions in futures contracts at December 31, 2018 and 2017 are reflected within the Condensed Schedules of Investments. G. Forward currency contracts Forward currency contracts are entered into as an economic hedge against foreign currency exchange rate risk related to portfolio positions. A forward currency contract is an obligation to purchase or sell a currency against another currency at a future date at an agreed upon price and quantity. Forward currency contracts are traded over-the-counter and not on an organized exchange. Forward currency contracts help to manage the overall exposure to the foreign currency backing some of the investments held by the Partnership. Each contract is marked-to-market daily and the change in market value is recorded by the Partnership as an unrealized gain or loss. When the contract is closed, the Partnership records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. The use of forward currency contracts involves the risk that counterparties may not meet the terms of the agreement or unfavorable movements in the value of a foreign currency relative to the U.S. dollar. Open forward currency contracts at December 31, 2018 and 2017 are reflected within the Condensed Schedules of Investments. H. Foreign Currency Transactions The Partnership’s functional currency is the U.S. dollar; however, it may transact business in currencies other than the U.S. dollar. Assets and liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the rates in effect at the date of the Statements of Financial Condition. Income and expense items denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the rates in effect during the period. Gains and losses resulting from the translation to U.S. dollars are reported in the Statements of Income (Loss). I. Cash The Partnership maintains a custody account with JPMorgan Chase Bank, N.A. At times, the Partnership’s cash balance could exceed the insured amount under the Federal Deposit Insurance Corporation (“FDIC”). The Partnership has not experienced any losses in such accounts and believes it is not subject to any significant counterparty risk related to its cash account. Both restricted cash and restricted foreign currency are held as margin collateral for futures transactions. J. Offering Costs Offering costs incurred in connection with the ongoing offering of the Partnership’s interests are borne by the Partnership. These costs include, but are not limited to, legal fees pertaining to updating the Partnership’s offering documents and materials, accounting and printing costs. These costs are charged as an expense when incurred. Offering costs are included in other expenses on the Statements of Income (Loss). K. Income Taxes The Partnership is treated as a partnership for U.S. federal income tax purposes. As such, the partners are individually liable for their own distributable share of taxable income or loss. No provision has been made in the accompanying financial statements for U.S., federal, state, or local income taxes. The Partnership is required to determine whether its tax positions are more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant taxing authority. De-recognition of a tax benefit previously recognized results in the Partnership recording a tax liability that reduces ending partners’ capital. Based on its analysis, the Partnership has determined that it has not incurred any liability for unrecognized tax benefits as of December 31, 2018, 2017 and 2016. However, the Partnership’s conclusions may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analyses of and changes to tax laws, regulations and interpretations thereof. The Partnership is subject to income tax examinations by major taxing authorities for all tax years since 2015. The Partnership recognizes interest and penalties related to unrecognized tax benefits in interest expense and other expenses, respectively. No interest expense or penalties have been recognized as of and for the years ended December 31, 2018, 2017 and 2016.

These events include the following: (i) the Clearing Broker is directed or required by a regulatory or self-regulatory organization, (ii) the Clearing Broker determines, at its discretion, that the risk in the Partnership’s account must be reduced for protection of the Clearing Broker, (iii) upon the Partnership’s breach or failure to perform on its contractual agreements with the Clearing Broker, (iv) upon the commencement of bankruptcy, insolvency or similar proceeding for the protection of creditors against the Partnership, or (v) upon the dissolution, winding-up, liquidation or merger of the Partnership. With respect to foreign currency forward contracts, the Partnership has entered into an agreement with the Clearing Broker, whereby the party having the greater obligation (either the Partnership or the Clearing Broker) shall deliver to the other party at the settlement date the net amount of recognized derivative assets and liabilities.

Investments, All Other Investments [Abstract]
FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND UNCERTAINTIES	NOTE 8 - FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND UNCERTAINTIES The Partnership participates in the speculative trading of commodity futures contracts and forward currency contracts, substantially all of which are subject to margin requirements. The minimum amount of margin required for each contract is set from time to time in response to various market factors by the respective exchanges and interbank market makers. Further for futures contracts and options on futures contracts, the Clearing Broker has the right to require margin in excess of the minimum exchange requirement. Risk arises from changes in the value of these contracts (market risk) and the potential inability of brokers or interbank market makers to perform under the terms of their contracts (credit risk). All of the contracts, with the exception of forward currency contracts, currently traded by the Partnership are exchange traded. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions because, in over-the-counter transactions, the Partnership must rely solely on the credit of its respective individual counterparties. For forward currency contracts, the Partnership is subject to the credit risk associated with counterparty non-performance. The credit risk from counterparty non-performance associated with such instruments is the net unrealized gain on forward currency contracts. The Partnership also has credit risk since the sole counterparty to all domestic futures contracts is the exchange clearing corporation. In addition, the Partnership bears the risk of financial failure by the Clearing Broker. The Partnership's policy is to continuously monitor its exposure to market and counterparty risk through the use of a variety of financial, position and credit exposure reporting and control procedures. In addition, the Partnership has a policy of reviewing the credit standing of each clearing broker or counterparty with which it conducts business. The Partnership has a substantial portion of its assets on deposit with the Custodian in U.S. government agency bonds and notes and corporate notes. Risks arise from investments in bonds and notes due to possible illiquidity and the potential for default by the issuer or counterparty. Such instruments are also sensitive to changes in interest rates and economic conditions.

1. ORGANIZATION AND SIGNIFICA_2

1. ORGANIZATION AND SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
General Description of the Partnership	A. General Description of the Partnership Altegris Winton Futures Fund, L.P. (the “Partnership”) was organized as a limited partnership in Colorado in March 1999, and will continue until December 31, 2035, unless sooner terminated as provided for in the Agreement of Limited Partnership (the “Agreement”), as amended and restated from time to time. The Partnership's general partner is Altegris Advisors, L.L.C. (the “General Partner”). The Partnership speculatively trades commodity futures contracts, options on futures contracts, forward contracts and other commodity interests. The objective of the Partnership’s business is appreciation of its assets. The Partnership is subject to the regulations of the Commodity Futures Trading Commission (the “CFTC”), an agency of the United States (“U.S.”) government that regulates most aspects of the commodity futures industry; rules of the National Futures Association, an industry self-regulatory organization; and the requirements of commodity exchanges and futures commission merchants (brokers) through which the Partnership trades.
Method of Reporting	B. Method of Reporting The Partnership’s financial statements are presented in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”). Therefore, the Partnership follows the accounting and reporting guidelines for investment companies. The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported fair value of assets and liabilities, disclosures of contingent assets and liabilities as of December 31, 2018 and 2017 and reported amounts of income and expenses for the years ended December 31, 2018, 2017 and 2016. Management believes that the estimates utilized in preparing the Partnership’s financial statements are reasonable; however, actual results could differ from these estimates and it is reasonably possible that differences could be material.
Fair Value	C. Fair Value In accordance with the authoritative guidance under U.S. GAAP, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the “exit price”) in an orderly transaction between market participants at the measurement date. In determining fair value, the Partnership uses various valuation approaches. The authoritative guidance under U.S. GAAP establishes a fair value hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are those that market participants would use in pricing the asset or liability based on market data obtained from sources independent of the Partnership. Unobservable inputs reflect the Partnership’s assumption about the inputs market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The fair value hierarchy is categorized into three levels based on the inputs as follows: Level 1 - Unadjusted quoted prices in active markets for identical, unrestricted assets or liabilities that the Partnership has the ability to access at the measurement date; Level 2 - Quoted prices which are not active, or inputs that are observable (either directly or indirectly) for substantially the full term of the asset or liability; and Level 3 - Prices, inputs or exotic modeling techniques which are both significant to the fair value measurement and unobservable (supported by little or no market activity). The availability of valuation techniques and observable inputs can vary from assets and liabilities and is affected by a wide variety of factors, including the type of asset or liability, whether the asset or liability is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Those estimated values do not necessarily represent the amounts that may be ultimately realized due to the occurrence of future circumstances that cannot be reasonably determined. Because of the inherent uncertainty of valuation, those estimated values may be materially higher or lower than the values that would have been used had a ready market for the asset or liability existed. Accordingly, the degree of judgment exercised by the Partnership in determining fair value is greatest for assets and liabilities categorized in Level 3. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement falls in its entirety is determined by the lowest level input that is significant to the fair value measurement. Fair value is a market-based measure considered from the perspective of a market participant rather than an entity-specific measure. Therefore, even when market assumptions are not readily available, the Partnership’s own assumptions are set to reflect those that market participants would use in pricing the asset or liability at the measurement date. The Partnership uses prices and inputs that are current as of the measurement date, including prices and inputs during periods of market dislocation. In periods of market dislocation, the observability of prices and inputs may be reduced for many assets and liabilities. This condition could cause an asset or liability to be reclassified to a lower level within the fair value hierarchy. The Partnership values futures and options on futures contracts at the closing price of the contrac t’s Foreign currency exchange contracts and foreign cross currency exchange contracts are valued at the mean between the bid and ask prices, which approximates fair value. Interpolated values are derived when the settlement date of the contract is an interim date for which quotations are not available. The Partnership includes forward currency contracts in Level 2 of the fair value hierarchy. Where available, the fair value of U.S. government agency bonds and notes is based on quoted prices in active markets. When quoted prices are not available, fair value is determined based on a valuation model that uses inputs that include interest-rate yield curves, cross-currency-basis index spreads, and country credit spreads similar to the bond in terms of issue, maturity and seniority. U.S. government agency bonds and notes are generally categorized in Levels 1 or 2 of the fair value hierarchy. As of December 31, 2018 and 2017, none of the Partnership’s holdings in U.S. government agency bonds and notes were fair valued using valuation models. The fair value of corporate notes is determined using recently executed transactions, market price quotations (where observable), notes spreads or credit default swap spreads. The spread data used are for the same maturity as that of the notes. If the spread data does not reference the issuer, data that references a comparable issuer is used. When observable price quotations are not available, fair value is determined based on cash flow models with yield curves, bond, or single-name credit default swap spreads and recovery rates based on collateral values as key inputs. These valuation methods represent both a market and income approach to fair value measurement. Corporate notes are categorized in Level 2 of the fair value hierarchy; however, in instances where significant inputs are unobservable, they are categorized in Level 3 of the hierarchy. As of December 31, 2018 and 2017, none of the Partnership’s holdings in corporate notes were fair valued using valuation models. The fair value of certificates of deposit is determined based on a constant maturity curve for comparable instruments denominated in USD. This valuation method represents both a market and income approach to fair value measurement. Certificates of deposit are categorized in Level 2 of the fair value hierarchy. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. There were no changes to the Partnership’s valuation methodology during the years ended December 31, 2018 and 2017. The following table presents information about the Partnership’s assets and liabilities measured at fair value as of December 31, 2018 and 2017: December 31, 2018 Level 1 Level 2 Level 3 Balance as of December 31, 2018 Assets: Futures contracts (1)* $ 3,399,238 $ – $ – $ 3,399,238 Forward currency contracts (1) – 331,450 – 331,450 U.S. Government agency bonds and notes – 70,186,759 – 70,186,759 Corporate notes – 40,317,094 – 40,317,094 Certificates of deposit – 6,012,013 – 6,012,013 $ 3,399,238 $ 116,847,316 $ – $ 120,246,554 Liabilities: Futures contracts (1)* $ (5,496,161 ) $ – $ – $ (5,496,161 ) Forward currency contracts (1) – (265,019 ) – (265,019 ) $ (5,496,161 ) $ (265,019 ) $ – $ (5,761,180 ) December 31, 2017 Level 1 Level 2 Level 3 Balance as of December 31, 2017 Assets: Futures contracts (1)* $ 7,042,156 $ – $ – $ 7,042,156 Forward currency contracts (1) – 2,248,858 – 2,248,858 U.S. Government agency bonds and notes – 101,514,933 – 101,514,933 Corporate notes – 51,991,344 – 51,991,344 $ 7,042,156 $ 155,755,135 $ – $ 162,797,291 Liabilities: Futures contracts (1)* $ (3,829,650 ) $ – $ – $ (3,829,650 ) Forward currency contracts (1) – (975,706 ) – (975,706 ) $ (3,829,650 ) $ (975,706 ) $ – $ (4,805,356 ) (1) See Note 7. “Financial Derivative Instruments” for the fair value in each type of contracts within this category. * Futures contracts include settled variation margin. The Partnership’s policy is to recognize any transfers between Level 1 and Level 2 assets as of the Partnership’s fiscal year-end. For the years ended December 31, 2018 and 2017, there were no transfers between Level 1 and Level 2 assets and liabilities. For the years ended December 31, 2018 and 2017, there were no Level 3 securities.
Investment Transactions and Investment Income	D. Investment Transactions and Investment Income Security transactions are recorded on the trade date for financial reporting purposes. Realized gains and losses from security transactions are determined using the specific identification cost method. Change in net unrealized gain or loss from the preceding period is reported in the Statements of Income (Loss). Brokerage commissions and other trading fees are reflected as an adjustment to cost or proceeds at the time of the transaction. Interest income is recorded on an accrual basis. Gains or losses on futures contracts, options on futures contracts and forward currency contracts are realized when contracts are closed. Net unrealized gains or losses on open contracts (the difference between contract trade price and quoted market price) are reflected in the Statements of Financial Condition. Any change in net unrealized gain or loss from the preceding period is reported in the Statements of Income (Loss). Brokerage commissions on futures and options on futures contracts include other trading fees and are recognized as trading gains and losses. Net realized gains and losses from foreign currency related transactions represent gains and losses from sales of foreign currencies, currency gains and losses realized between trade and settlement dates on securities transactions, and the difference between the amounts of interest and foreign withholding taxes recorded on the Partnership’s books and the U.S. Dollar equivalent of the amounts actually received or paid. Net unrealized gain (loss) on other assets and other liabilities denominated in foreign currency arise from changes in the value of assets, other than investments in securities, and liabilities at fiscal year-end, resulting from changes in the exchange rates. J.P. Morgan Chase Bank, N.A. (the “Custodian”) is the Partnership’s custodian. SG Americas Securities, LLC (the “Clearing Broker”) is the Partnership’s commodity broker. A portion of the Partnership’s assets are held as initial margin or option premiums (in cash or Treasury securities) in the Partnership’s brokerage accounts at the Clearing Broker. The Clearing Broker may convert the Partnership’s cash in U.S. dollar to foreign currency to facilitate the Partnership’s commodity trading activities. At times, the Partnership may carry foreign cash on loan with the Clearing Broker. Any net foreign currency on loan will be recognized in Foreign Currency Due to Broker on the Statements of Financial Condition. The Partnership’s Clearing Broker holds margin balances in a single currency, in which all margin requirements can be satisfied in U.S. dollars. Foreign currency balances can also be used to satisfy margin requirements. As of December 31, 2018 and December 31, 2017, the Partnership’s restricted cash balance on the Statements of Financial Condition of $8,266,227 and $16,699,269, respectively, represents the collateral pledged by the Partnership to satisfy the Clearing Broker’s margin requirements in US Dollars. As of December 31, 2018 and December 31, 2017, the Partnership’s restricted foreign currency balance on the Statements of Financial Condition of $637,770 and $2,962,145, respectively, represents the collateral pledged by the Partnership to satisfy the Clearing Broker’s margin requirements in foreign currency. The Partnership’s assets not deposited at the Clearing Broker are deposited with either the Custodian or held in bank cash accounts at Northern Trust Company (and used to pay Partnership operating expenses). For the Partnership’s cash deposited at the Custodian, the Partnership receives cash management services from J.P. Morgan Investment Management Inc. (“JPMIM”).
Option Contracts	E. Option Contracts Generally, an option is a contract that gives the purchaser of the option, in return for the premium paid, the right to buy a specified security, currency or other instrument (an ‘‘underlying instrument’’) from the writer of the option (in the case of a call option), or to sell a specified security, currency, or other instrument to the writer of the option (in the case of put option) at a designated price. Put and call options that the Partnership may purchase or write may be traded on a national securities exchange or in the over-the-counter (OTC) market. All option positions entered into on a national securities exchange are cleared and guaranteed by the options clearing corporation, thereby reducing the risk of counterparty default. There can be no assurance that a liquid secondary market will exist for any option purchased or sold. As the buyer of an option, the Partnership has a right to buy (call option) or sell (put option) the underlying instrument at the exercise price. The Partnership may enter into closing sale transactions with respect to options, exercise them, or permit them to expire unexercised. When buying options, the potential loss is limited to the cost (premium plus transaction costs) of the option. As the writer of an option, the Partnership has the obligation to buy (call option) or sell (put option) the underlying instrument at the exercise price. When the Partnership writes an option, an amount equal to the premium received by the Partnership is recorded as a liability and subsequently marked to market to reflect the current value of the option written. If the written option expires unexercised, the Partnership realizes a gain in the amount of the premium received. If the Partnership enters into a closing transaction, it recognizes a gain or loss, depending on whether the cost of the purchase is less than or greater than the premium received. If the option is exercised, the Partnership will incur a loss to the extent the difference between the current market value of the underlying instrument and the exercise price exceeds the premium received. As the writer of a call option, the Partnership retains the risk of loss should the underlying instrument increase in value. If the option is exercised, the Partnership will be required to buy or sell the instrument at the exercise price. Accordingly, these transactions result in off-balance sheet risk, as the Partnership’s ultimate obligation may exceed the amount indicated in the Statements of Financial Condition. As of December 31, 2018 and 2017, the Partnership did not hold any option contracts.
Futures Contracts	F. Futures Contracts The Partnership engages in futures contracts as part of its investment strategy. Upon entering into a futures contract, the Partnership is required to deposit with the broker an amount of cash or cash equivalents equal to a certain percentage of the contract amount. This is known as the initial margin. Subsequent payments (“variation margin”) are made or received by the Partnership each day, depending on the daily fluctuations in the value of the contract, and are included in settled variation margin on the Statements of Financial Condition. Due to broker amounts on the Statements of Financial Condition represent the amount of any short fall in the Fund's required cash margin. The Partnership recognizes a realized gain or loss when the contract is closed. There are several risks in connection with the use of futures contracts as an investment option. The change in value of futures contracts primarily corresponds with the value of their underlying instruments. In addition, there is the risk that the Partnership may not be able to enter into a closing transaction because of an illiquid secondary market. Open positions in futures contracts at December 31, 2018 and 2017 are reflected within the Condensed Schedules of Investments.
Forward currency contracts	G. Forward currency contracts Forward currency contracts are entered into as an economic hedge against foreign currency exchange rate risk related to portfolio positions. A forward currency contract is an obligation to purchase or sell a currency against another currency at a future date at an agreed upon price and quantity. Forward currency contracts are traded over-the-counter and not on an organized exchange. Forward currency contracts help to manage the overall exposure to the foreign currency backing some of the investments held by the Partnership. Each contract is marked-to-market daily and the change in market value is recorded by the Partnership as an unrealized gain or loss. When the contract is closed, the Partnership records a realized gain or loss equal to the difference between the value at the time it was opened and the value at the time it was closed. The use of forward currency contracts involves the risk that counterparties may not meet the terms of the agreement or unfavorable movements in the value of a foreign currency relative to the U.S. dollar. Open forward currency contracts at December 31, 2018 and 2017 are reflected within the Condensed Schedules of Investments.
Foreign Currency Transactions	H. Foreign Currency Transactions The Partnership’s functional currency is the U.S. dollar; however, it may transact business in currencies other than the U.S. dollar. Assets and liabilities denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the rates in effect at the date of the Statements of Financial Condition. Income and expense items denominated in currencies other than the U.S. dollar are translated into U.S. dollars at the rates in effect during the period. Gains and losses resulting from the translation to U.S. dollars are reported in the Statements of Income (Loss).
Cash	I. Cash The Partnership maintains a custody account with JPMorgan Chase Bank, N.A. At times, the Partnership’s cash balance could exceed the insured amount under the Federal Deposit Insurance Corporation (“FDIC”). The Partnership has not experienced any losses in such accounts and believes it is not subject to any significant counterparty risk related to its cash account. Both restricted cash and restricted foreign currency are held as margin collateral for futures transactions.
Offering Costs	J. Offering Costs Offering costs incurred in connection with the ongoing offering of the Partnership’s interests are borne by the Partnership. These costs include, but are not limited to, legal fees pertaining to updating the Partnership’s offering documents and materials, accounting and printing costs. These costs are charged as an expense when incurred. Offering costs are included in other expenses on the Statements of Income (Loss).
Income Taxes	K. Income Taxes The Partnership is treated as a partnership for U.S. federal income tax purposes. As such, the partners are individually liable for their own distributable share of taxable income or loss. No provision has been made in the accompanying financial statements for U.S., federal, state, or local income taxes. The Partnership is required to determine whether its tax positions are more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any related appeals or litigation processes, based on the technical merits of the position. The tax benefit recognized is measured as the largest amount of benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement with the relevant taxing authority. De-recognition of a tax benefit previously recognized results in the Partnership recording a tax liability that reduces ending partners’ capital. Based on its analysis, the Partnership has determined that it has not incurred any liability for unrecognized tax benefits as of December 31, 2018, 2017 and 2016. However, the Partnership’s conclusions may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analyses of and changes to tax laws, regulations and interpretations thereof. The Partnership is subject to income tax examinations by major taxing authorities for all tax years since 2015. The Partnership recognizes interest and penalties related to unrecognized tax benefits in interest expense and other expenses, respectively. No interest expense or penalties have been recognized as of and for the years ended December 31, 2018, 2017 and 2016.
