ORGANIZATION AND BUSINESS
ORGANIZATION AND BUSINESS	NOTE 1 — ORGANIZATION AND BUSINESS The USCF Funds Trust (the “Trust”) was a Delaware statutory trust formed on March 2, 2016. The Trust was a series trust formed pursuant to the Delaware Statutory Trust Act. United States 3x Oil Fund (“USOU”) and United States 3x Short Oil Fund (“USOD”) were both series of the Trust. Two other series: REX S&P MLP Fund (“RMLP”), and REX S&P MLP Inverse Fund (“MLPD”, together with RMLP, the “REX Funds”)) never commenced operations and filed to withdraw from registration on March 30, 2018. USOU and USOD were commodity pools that continuously issue common shares of beneficial interest that may be purchased and sold on NYSE Arca Equities, Inc. stock exchange (“NYSE Arca”). USOU and USOD each referred to as the “Fund” and collectively referred to herein as the “Funds” or the “Trust Series.” The Trust and the Funds operated pursuant to the Trust’s Amended and Restated Declaration of Trust and Trust Agreement (the “Trust Agreement”), dated as of June 23, 2017. The sole trustee of the Trust is Wilmington Trust Company, National Association, a national banking association, with its principal place of business in the State of Delaware (the “Trustee”). The Trust and the Funds are managed and operated by the United States Commodity Funds, LLC (“USCF” or the “Sponsor”). USCF is a limited liability company formed in Delaware on May 10, 2005, that is registered as a commodity pool operator (“CPO”) with the Commodity Futures Trading Commission (“CFTC”) and is a member of the National Futures Association (“NFA”).

The Sponsor also has the exclusive power to fix and determine the relative rights and preferences as between the shares of any series as to right of redemption, special and relative rights as to dividends and other distributions and on liquidation, conversion rights, and conditions under which the series shall have separate voting rights or no voting rights. The term for which the Trust will exist commenced on the date of the filing of the Certificate of Trust, and the Trust and any Fund will exist in perpetuity, unless earlier terminated in accordance with the provisions of the Trust Agreement. Each Fund is separate from all other Funds created as series of the Trust in respect of the assets and liabilities allocated to that Fund and each Fund represents a separate investment portfolio of the Trust. Separate and distinct records must be maintained for each Fund and the assets associated with a Fund shall be held in such separate and distinct records (directly or indirectly, including a nominee or otherwise) and accounted for in such separate and distinct records separately from the assets of any other Fund. The Trustee is not affiliated with the Sponsor. The Trustee will accept legal service of process on the Trust in the State of Delaware and will make certain filings under the Delaware Statutory Trust Act. The Trustee’s duties and liabilities with respect to the offering of Shares and the management of the Trust are limited to its express obligations under the Trust Agreement and the Trustee does not owe any other duties to the Trust, the Sponsor or the shareholders of any Fund.

The USCF Funds Trust, including each of its series USOU and USOD filed a current report on Form 8-K dated November 20, 2019 with the U.S. Securities and Exchange Commission (“SEC”) that included, as an exhibit, the press release and the applicable plan of liquidation. In addition, each of USOU and USOD filed a prospectus supplement with the SEC dated November 19, 2019. The liquidation date for each of USOU and USOD was December 18, 2019 and the proceeds of the liquidation were sent to all remaining shareholders of USOU and USOD, respectively, on or about December 19, 2019. Each of USOU and USOD also filed a post-effective amendment to the registration statement with the SEC to terminate the offering of registered and unsold shares of USOU and USOD, respectively, and the NYSE Arca filed Forms 25 to effect the withdrawal of the listings for shares of each of USOU and USOD. On October 3, 2019, after the close of trading on the NYSE Arca, USOD effected a 1-for-2 reverse share split and post-split shares of USOD began trading on October 4, 2019. As a result of the reverse share split, every two pre-split shares of USOD were automatically exchanged for one post-split share. Immediately prior to the reverse split, there were 1,650,040 shares of USOD issued and outstanding, representing a per share NAV of $4.33. Immediately after the reverse share split, the number of issued and outstanding shares of USOD decreased to 825,040, not accounting for fractional shares, and the per share NAV increased to $8.66. In connection with the reverse share split, the CUSIP number for USOD’s shares changed to 91733T505. USOD’s ticker symbol, “USOD,” remains the same. USO, UNG, UGA, UNL, USL, BNO, USCI and CPER are referred to collectively herein as the “Related Public Funds.” Effective as of July 20, 2017, each of USOU and USOD issued shares to certain authorized purchasers (“Authorized Participants”) by offering baskets consisting of 50,000 shares (“Creation Baskets”) through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). The purchase price for a Creation Basket of USOU or USOD, as applicable, is based upon the net asset value (“NAV”) of a share of USOU or USOD, as applicable, calculated shortly after the close of the core trading session on the NYSE Arca on the day the order to create the basket is properly received. Authorized Participants pay USOU and USOD, as applicable, a transaction fee equal to 0.04% of total NAV of the Creation Baskets for each order placed to create one or more Creation Baskets or to redeem one or more baskets (“Redemption Baskets”), consisting of 50,000 shares. The transaction fee may be waived, reduced, increased or otherwise changed by USCF. Shares may be purchased or sold on a nationally recognized securities exchange in smaller increments than a Creation Basket or Redemption Basket. Shares purchased or sold on a nationally recognized securities exchange are not purchased or sold at the per share NAV of each Fund but rather at market prices quoted on such exchange.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	Dec. 31, 2019
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 — SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. Each series of the Trust is an investment company and follows the accounting and reporting guidance in FASB Topic 946. The Trust financial statements included its respective series of funds financial statements including USOU, USOD and the REX Funds through December 31, 2017. For reporting commencing with the March 31, 2018 reporting period, and in conjunction with the termination of the REX Funds on March 30, 2018 the REX Funds financial statements have not been included, but are included in the overall Trust financial statements for the applicable reporting periods. Revenue Recognition Commodity futures contracts, forward contracts, physical commodities and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the statements of financial condition and represent the difference between the original contract amount and the market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the financial statements. Changes in the unrealized gains or losses between periods are reflected in the statements of operations. The Funds earn income on funds held at the custodian or a futures commission merchant (“FCM”) at prevailing market rates earned on such investments. Brokerage Commissions Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis. Income Taxes The Funds are not subject to federal income taxes; each investor reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return. In accordance with U.S. GAAP, each Fund is required to determine whether a tax position is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any tax related appeals or litigation processes, based on the technical merits of the position. Each Fund files an income tax return in the U.S. federal jurisdiction and may file income tax returns in various U.S. states. None of the Trust Series is subject to income tax return examinations by major taxing authorities for years before 2017 (commencement of operations). 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. De-recognition of a tax benefit previously recognized results in each Trust Series recording a tax liability that reduces net assets. However, each Trust Series’ conclusions regarding this policy may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analysis of and changes to tax laws, regulations and interpretations thereof. Each Trust Series recognizes interest accrued related to unrecognized tax benefits and penalties related to unrecognized tax benefits in income tax fees payable, if assessed. No interest expense or penalties have been recognized as of and for the year ended December 31, 2019 for any Trust Series. Creations and Redemptions Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 shares at a price equal to the NAV of the shares calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed. The Funds receive or pay the proceeds from shares sold or redeemed within two business days after the trade date of the purchase or redemption. The amounts due from Authorized Participants are reflected in the Funds’ statements of financial condition as receivable for shares sold and amounts payable to Authorized Participants upon redemption are reflected as payable for shares redeemed. For USOU or USOD, Authorized Participants pay a transaction fee equal to 0.04% of total NAV of baskets to the Fund for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. The transaction fee may be waived, reduced, increased or otherwise changed by USCF. Trust Capital and Allocation of Income and Losses The Trust is treated as a partnership for tax purposes. Profit or loss shall be allocated among the shareholders of each Trust Series in proportion to the number of shares each investor holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the Trust Agreement . Calculation of Per Share NAV USOU and USOD Funds’ per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing that amount by the total number of shares outstanding. The Funds use the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange. The NAV for a normal trading day is released after 4:00 p.m. Eastern time (“E.T.”). For futures contracts and options traded on exchanges, USOU and USOD’s administrator (the “Administrator”) use the closing or settlement price published by the applicable exchange or, in the case of a market disruption, the last traded price before settlement. In the case of the Benchmark Oil Futures Contract, the NYMEX closing price (determined at the earlier of the close of the NYMEX or 2:30 p.m. E.T.) for the contracts traded on the NYMEX is used. Other investments’ values for purposes of determining the NAV for each of USOU and USOD, including Treasuries, cash equivalents (other than money market funds), cleared and non-cleared swaps, forwards, options and swaps are calculated by the Administrator using market quotations and market data, if available, or other information customarily used to determine the fair value of such investments as of the earlier of the close of the NYSE Arca or 4:00 p.m. E.T. Money market funds are valued at their end of day NAV. Net Income (Loss) Per Share Net income (loss) per share is the difference between the per share NAV at the beginning of each period and at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. As of December 31, 2019, USCF did not hold any shares of each of USOU and USOD. Offering Costs Offering costs incurred in connection with the registration of additional shares of any Trust Series after the initial registration of shares of such Trust Series are borne by each respective Trust Series. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. These costs are accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight-line basis or a shorter period if warranted. Cash Equivalents Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of six months or less. Reclassification Certain amounts in the accompanying financial statements were reclassified to conform to the current presentation. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires USCF to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of the revenue and expenses during the reporting period. Actual results may differ from those estimates and assumptions.

TRUST SERIES

TRUST SERIES	12 Months Ended
TRUST SERIES	Dec. 31, 2019
TRUST SERIES
TRUST SERIES	NOTE 3 — TRUST SERIES Pursuant to the Trust Agreement, four series have been designated as series of the Trust. Following the designation of the Funds as a series of the Trust, an initial capital contribution of $1,000 was made to each respective Fund by the Sponsor and deemed an initial contribution of capital to each respective Fund. The Sponsor contributed an aggregate of $4,000 to the Trust, $1,000 on March 31, 2016 for RMLP, $1,000 on April 15, 2016 for MLPD, $1,000 on June 20, 2017 for USOU and $1,000 on June 20, 2017 for USOD. As of December 31, 2019, RMLP and MLPD were no longer in registration. In connection with the commencement of trading for USOU and USOD under each Fund’s ticker, and the initial offering of shares, USCF received 40 Sponsor Shares of each of USOU and USOD in exchange for the previously received capital contribution, representing a beneficial ownership interest in each Fund. As of December 31, 2019, USCF did not hold any shares of each of USOU and USOD. On July 19, 2017, the Trust received a notice of effectiveness from the U.S. Securities and Exchange Commission (the “SEC”) for its registration of 30,000,000 shares of USOU and 30,000,000 shares of USOD on Form S‑1 with the SEC. The order to permit listing of USOU and USOD shares on the NYSE Arca was received on July 20, 2017. On July 20, 2017, USOU and USOD listed their shares on the NYSE Arca under the ticker symbols “USOU” and “USOD,” respectively. USOU and USOD established their initial per share NAV by setting the price at $25.00. In order to satisfy NYSE Arca listing standards that at least 100,000 shares be outstanding at the beginning of the trading day on the NYSE Arca, on July 20, 2017, each Fund issued 100,000 shares to the initial Authorized Participant, RBC Capital Markets, LLC in exchange for $2,500,000 for USOU and $2,500,000 for USOD. Each of USOU and USOD also commenced investment operations on July 20, 2017 by purchasing Futures Contracts traded on the Futures Exchanges. Investment Objective of the Funds USOU USOU’s shares traded on the NYSE Arca. The investment objective of USOU was for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to reflect three times (3x) the daily change in percentage terms of the price of a specified short-term futures contract on light, sweet crude oil (the “Benchmark Oil Futures Contract”) less USOU’s expenses. To achieve this objective, USCF endeavored to have the notional value of USOU’s aggregate exposure to the Benchmark Oil Futures Contract at the close of each trading day approximately equal to 300% of its NAV. USOU sought a return that is 300% of the return of the Benchmark Oil Futures Contract for a single day and did not seek to achieve its stated investment objective over a period of time greater than one day . The pursuit of daily leveraged investment goals means that the return of USOU for a period longer than a full trading day may have no resemblance to 300% of the return of the Benchmark Oil Futures Contract for a period of longer than a full trading day because the aggregate return of USOU is the product of the series of each trading day’s daily returns. USOU’s shares began trading on July 20, 2017 and ceased trading on December 12, 2019. As of December 31, 2019, USOU had liquidated all its assets and distributed cash pro rata to all remaining shareholders. USOD USOD’s shares traded on the NYSE Arca. The investment objective of USOD was for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to reflect three times the inverse (‑3x) of the daily change in percentage terms of the price of a specified short-term futures contract on light, sweet crude oil (the “Benchmark Oil Futures Contract”) less USOD’s expenses. To achieve this objective, USCF endeavored to have the notional value of USOD’s aggregate short exposure to the Benchmark Oil Futures Contract at the close of each trading day approximately equal to 300% of its NAV. USOD sought a return that is -300% of the return of the Benchmark Oil Futures Contract for a single day and did not seek to achieve its stated investment objective over a period of time greater than one day . The pursuit of daily inverse leveraged investment goals means that the return of USOD for a period longer than a full trading day may have no resemblance to -300% of the return of the Benchmark Oil Futures Contract for a period of longer than a full trading day because the aggregate return of USOD is the product of the series of each trading day’s daily returns. USOD’s shares began trading on July 20, 2017 and ceased trading on December 12, 2019. As of December 31, 2019, USOD had liquidated all its assets and distributed cash pro rata to all remaining shareholders. Trading Advisor and Trustee The Trustee accepts service of legal process on the Trust in the State of Delaware and makes certain filings under the Delaware Statutory Trust Act. The Trustee does not owe any other duties to the Trust, USCF or the shareholders.

During the years ended December 31, 2019, 2018 and 2017, the Trust Series did not incur registration fees or other offering expenses. Independent Directors’ and Officers’ Expenses The Sponsor was responsible for paying its portion of the directors’ and officers’ liability insurance for the Funds and the fees and expenses of the independent directors who also serve as audit committee members of the Funds. The directors also serve as the directors, and for the independent directors as audit committee members, of the Related Public Funds and the other Funds that are series of the Trust.

These fees and expenses for the year ended December 31, 2019 amounted to be a total of $556,951 for the Funds and the Related Public Funds. USOU’s portion of such fees and expenses for the year ended December 31, 2019 was $0 and USOD’s portion of such fees and expenses for the year ended December 31, 2019 was $0. For the year ended December 31, 2018, these fees and expenses were $521,689 for the Funds and the Related Public Funds. USOU’s portion of such fees and expenses for the year ended December 31, 2018 was $0 and USOD’s portion of such fees and expenses for the year ended December 31, 2018 was $00. Investor Tax Reporting Cost The fees and expenses associated with the Funds’ audit expenses and tax accounting and reporting requirements are paid by the Sponsor. These costs were approximately $90,000 for the year ended December 31, 2019 for USOU and USOD. Tax reporting costs fluctuate between years due to the number of shareholders during any given year. Other Expenses and Fees In addition to the fees described above, each Active Fund pays all brokerage fees and other expenses in connection with the operation of such Active Fund, excluding costs and expenses paid by USCF as outlined in Note 5 – Contracts and Agreements below.

In no event may the aggregate compensation paid to the Marketing Agent and any affiliate of the Sponsor for distribution-related services exceed 10% of the gross proceeds of each Funds’ offering. The above fee did not include website construction and development, which are also borne by the Sponsor. Brown Brothers Harriman & Co. Agreements The Sponsor and the Trust, on its own behalf and on behalf of the Funds, were also party to a custodian agreement, dated July 7, 2017, as amended from time to time, with Brown Brothers Harriman & Co. (“BBH&Co.”) and USCF, whereby BBH&Co. held investments on behalf of the Trust Series. The Sponsor paid the fees of the custodian, which were determined by the parties from time to time. In addition, the Sponsor and the Trust, on its own behalf and on behalf of the Funds, were party to an administrative agency agreement, dated July 7, 2017, as amended from time to time, with BBH&Co., whereby BBH&Co. acted as the administrative agent, transfer agent and registrar for the Funds. The Sponsor also paid the fees of BBH&Co. for its services under such agreement and such fees were determined by the parties from time to time.

The Sponsor also pays BBH&Co. transaction fees ranging from $7 to $15 per transaction. Brokerage and Futures Commission Merchant Agreements On July 6, 2017, the Trust entered into a futures commission merchant agreement with RBC to serve as the FCM for each Fund. The agreement with RBC required it to provide services to each Fund in connection with the purchase and sale of Oil Futures Contracts and Other Oil-Related Investments that may have been purchased and sold by or through RBC for each Fund's account. In accordance with the agreement, RBC charged each Fund commissions of approximately $7 to $8 per round-turn trade, including applicable exchange, clearing and NFA fees for Oil Futures Contracts and options on Oil Futures Contracts. Such fees included those incurred when purchasing Oil Futures Contracts and options on Oil Futures Contracts when a Fund issued shares as a result of a Creation Basket, as well as fees incurred when selling Oil Futures Contracts and options on Oil Futures Contracts when a Fund redeemed shares as a result of a Redemption Basket. Such fees were also incurred when Oil Futures Contracts and options on Oil Futures Contracts were purchased or redeemed for the purpose of rebalancing the portfolio. Each Fund also incured commissions to brokers for the purchase and sale of Oil Futures Contracts, Other Oil-Related Investments or short-term obligations of the United States of two years or less (“Treasuries”).

FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES
FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES	NOTE 6 — FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES The Trust Series may engage in the trading of futures contracts, options on futures contracts, cleared swaps and OTC swaps (collectively, “derivatives”). The Trust Series are exposed to both market risk, which is the risk arising from changes in the market value of the contracts, and credit risk, which is the risk of failure by another party to perform according to the terms of a contract. The Trust Series may enter into futures contracts, options on futures contracts and cleared swaps to gain exposure to changes in the value of an underlying commodity. A futures contract obligates the seller to deliver (and the purchaser to accept) the future delivery of a specified quantity and type of a commodity at a specified time and place. Some futures contracts may call for physical delivery of the asset, while others are settled in cash. The contractual obligations of a buyer or seller may generally be satisfied by taking or making physical delivery of the underlying commodity or by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of delivery. Cleared swaps are agreements that are eligible to be cleared by a clearinghouse, e.g., ICE Clear Europe, and provide the efficiencies and benefits that centralized clearing on an exchange offers to traders of futures contracts, including credit risk intermediation and the ability to offset positions initiated with different counterparties. The purchase and sale of futures contracts, options on futures contracts and cleared swaps require margin deposits with an FCM. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires an FCM to segregate all customer transactions and assets from the FCM’s proprietary activities. Futures contracts, options on futures contracts and cleared swaps involve, to varying degrees, elements of market risk (specifically commodity price risk) and exposure to loss in excess of the amount of variation margin. The face or contract amounts reflect the extent of the total exposure each of the Trust Series has in the particular classes of instruments. Additional risks associated with the use of futures contracts are an imperfect correlation between movements in the price of the futures contracts and the market value of the underlying securities and the possibility of an illiquid market for a futures contract. Buying and selling options on futures contracts exposes investors to the risks of purchasing or selling futures contracts. All of the futures contracts held by USOU and USOD through December 31, 2019 were exchange-traded. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with OTC swaps since, in OTC swaps, a party must rely solely on the credit of its respective individual counterparties. However, in the future, if any of the Funds were to enter into non-exchange traded contracts, it would be 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, if any, on the transaction. The Funds have credit risk under its futures contracts since the sole counterparty to all domestic and foreign futures contracts is the clearinghouse for the exchange on which the relevant contracts are traded. In addition, the Funds bear the risk of financial failure by the clearing broker. The Trust Series’ cash and other property, such as Treasuries, deposited with an FCM are considered commingled with all other customer funds, subject to the FCM’s segregation requirements. In the event of an FCM’s insolvency, recovery may be limited to a pro rata share of segregated funds available. It is possible that the recovered amount could be less than the total of cash and other property deposited. The insolvency of an FCM could result in the complete loss of each of the Funds’ assets posted with that FCM; however, the majority of the Funds’ assets are held in investments in Treasuries, cash and/or cash equivalents with the Funds’ custodian and would not be impacted by the insolvency of an FCM. The failure or insolvency of the Funds’ custodian, however, could result in a substantial loss of the Funds’ assets. The Sponsor invests a portion of the Trust Series’ cash in money market funds that seek to maintain a stable per share NAV. The Trust Series are exposed to any risk of loss associated with an investment in such money market funds. As of December 31, 2019, none of the Trust Series held investments in money market funds. As of December 31, 2018, USOU and USOD held investments in money market funds in the amounts of $2,319,000 and $345,000, respectively. USOU and USOD also hold cash deposits with its custodian. Pursuant to a written agreement with BBH&Co., uninvested overnight cash balances are swept to offshore branches of U.S. regulated and domiciled banks located in Toronto, Canada; London, United Kingdom; Grand Cayman, Cayman Islands; and Nassau, Bahamas; which are subject to U.S. regulation and regulatory oversight. As of December 31, 2019 and December 31, 2018, USOU held cash deposits and investments in Treasuries in the amounts of $3,540 and $16,617,552, respectively, with the custodian and FCM. As of December 31, 2019 and December 31, 2018, USOD held cash deposits and investments in Treasuries in the amounts of $1,798 and $2,169,153, respectively, with the custodian and FCM. Some or all of these amounts may be subject to loss should USOU’s or USOD’s custodian and/or FCM cease operations. For derivatives, risks arise from changes in the market value of the contracts. Theoretically, the Trust Series are exposed to market risk equal to the value of futures contracts purchased and unlimited liability on such contracts sold short. As both a buyer and a seller of options, the Trust Series pay or receive a premium at the outset and then bear the risk of unfavorable changes in the price of the contract underlying the option. The Trust Series’ 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 controls and procedures. In addition, the Trust Series have a policy of requiring review of the credit standing of each broker or counterparty with which it conducts business. The financial instruments held by the Trust Series are reported in its statements of financial condition at market or fair value, or at carrying amounts that approximate fair value, because of their highly liquid nature and short-term maturity.

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS	12 Months Ended
FAIR VALUE OF FINANCIAL INSTRUMENTS	Dec. 31, 2019
FAIR VALUE OF FINANCIAL INSTRUMENTS
FAIR VALUE OF FINANCIAL INSTRUMENTS	NOTE 9 — FAIR VALUE OF FINANCIAL INSTRUMENTS The Trust and the Trust Series value their investments in accordance with Accounting Standards Codification 820 – Fair Value Measurements and Disclosures (“ASC 820”). ASC 820 defines fair value, establishes a framework for measuring fair value in generally accepted accounting principles, and expands disclosures about fair value measurement. The changes to past practice resulting from the application of ASC 820 relate to the definition of fair value, the methods used to measure fair value, and the expanded disclosures about fair value measurement. ASC 820 establishes a fair value hierarchy that distinguishes between: (1) market participant assumptions developed based on market data obtained from sources independent of the Trust and the Trust Series (observable inputs) and (2) the Trust’s and the Trust Series’ own assumptions about market participant assumptions developed based on the best information available under the circumstances (unobservable inputs). The three levels defined by the ASC 820 hierarchy are as follows: Level I – Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level II – Inputs other than quoted prices included within Level I that are observable for the asset or liability, either directly or indirectly. Level II assets include the following: quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market-corroborated inputs). Level III – Unobservable pricing input at the measurement date for the asset or liability. Unobservable inputs shall be used to measure fair value to the extent that observable inputs are not available. In some instances, the inputs used to measure fair value might fall within different levels of the fair value hierarchy. The level in the fair value hierarchy within which the fair value measurement in its entirety falls shall be determined based on the lowest input level that is significant to the fair value measurement in its entirety. As noted above, as of the filing of this annual report on Form 10-K, USOU and USOD is no longer issuing shares and has liquidated and distributed all proceeds to shareholders. As a result, there is no information available as of December 31, 2019. The following table summarizes the valuation of USOU’s securities at December 31, 2018 using the fair value hierarchy: At December 31, 2018 Total Level I Level II Level III Short-Term Investments $ 3,462,297 $ 3,462,297 $ — $ — Exchange-Traded Futures Contracts United States Contracts (3,899,053) (3,899,053) — — During the year ended December 31, 2018, there were no transfers between Level I and Level II.

RECENT ACCOUNTING PRONOUNCEMENTS	NOTE 10 — RECENT ACCOUNTING PRONOUNCEMENTS In August 2018, the FASB issued Accounting Standards Update (“ASU”) No. 2018-13, which changes certain fair value measurement disclosure requirements. The new ASU, in addition to other modifications and additions, removes the requirement to disclose the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, and the Funds’ policy for the timing of transfers between levels. The amendments are effective for financial statements issued for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The Trust Series has evaluated the implications of certain provisions of the ASU and has determined that there will be no material impacts to the financial statements.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	Dec. 31, 2019
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation	Basis of Presentation The financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") as detailed in the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification. Each series of the Trust is an investment company and follows the accounting and reporting guidance in FASB Topic 946. The Trust financial statements included its respective series of funds financial statements including USOU, USOD and the REX Funds through December 31, 2017. For reporting commencing with the March 31, 2018 reporting period, and in conjunction with the termination of the REX Funds on March 30, 2018 the REX Funds financial statements have not been included, but are included in the overall Trust financial statements for the applicable reporting periods.
Revenue Recognition	Revenue Recognition Commodity futures contracts, forward contracts, physical commodities and related options are recorded on the trade date. All such transactions are recorded on the identified cost basis and marked to market daily. Unrealized gains or losses on open contracts are reflected in the statements of financial condition and represent the difference between the original contract amount and the market value (as determined by exchange settlement prices for futures contracts and related options and cash dealer prices at a predetermined time for forward contracts, physical commodities, and their related options) as of the last business day of the year or as of the last date of the financial statements. Changes in the unrealized gains or losses between periods are reflected in the statements of operations. The Funds earn income on funds held at the custodian or a futures commission merchant (“FCM”) at prevailing market rates earned on such investments.
Brokerage Commissions	Brokerage Commissions Brokerage commissions on all open commodity futures contracts are accrued on a full-turn basis.
Income Taxes	Income Taxes The Funds are not subject to federal income taxes; each investor reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return. In accordance with U.S. GAAP, each Fund is required to determine whether a tax position is more likely than not to be sustained upon examination by the applicable taxing authority, including resolution of any tax related appeals or litigation processes, based on the technical merits of the position. Each Fund files an income tax return in the U.S. federal jurisdiction and may file income tax returns in various U.S. states. None of the Trust Series is subject to income tax return examinations by major taxing authorities for years before 2017 (commencement of operations). 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. De-recognition of a tax benefit previously recognized results in each Trust Series recording a tax liability that reduces net assets. However, each Trust Series’ conclusions regarding this policy may be subject to review and adjustment at a later date based on factors including, but not limited to, on-going analysis of and changes to tax laws, regulations and interpretations thereof. Each Trust Series recognizes interest accrued related to unrecognized tax benefits and penalties related to unrecognized tax benefits in income tax fees payable, if assessed. No interest expense or penalties have been recognized as of and for the year ended December 31, 2019 for any Trust Series.
Creations and Redemptions	Creations and Redemptions Authorized Participants may purchase Creation Baskets or redeem Redemption Baskets only in blocks of 50,000 shares at a price equal to the NAV of the shares calculated shortly after the close of the core trading session on the NYSE Arca on the day the order is placed. The Funds receive or pay the proceeds from shares sold or redeemed within two business days after the trade date of the purchase or redemption. The amounts due from Authorized Participants are reflected in the Funds’ statements of financial condition as receivable for shares sold and amounts payable to Authorized Participants upon redemption are reflected as payable for shares redeemed. For USOU or USOD, Authorized Participants pay a transaction fee equal to 0.04% of total NAV of baskets to the Fund for each order placed to create one or more Creation Baskets or to redeem one or more Redemption Baskets. The transaction fee may be waived, reduced, increased or otherwise changed by USCF.
Trust Capital and Allocation of Income and Losses	Trust Capital and Allocation of Income and Losses The Trust is treated as a partnership for tax purposes. Profit or loss shall be allocated among the shareholders of each Trust Series in proportion to the number of shares each investor holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the Trust Agreement .
Calculation of Per Share NAV	Calculation of Per Share NAV USOU and USOD Funds’ per share NAV is calculated on each NYSE Arca trading day by taking the current market value of its total assets, subtracting any liabilities and dividing that amount by the total number of shares outstanding. The Funds use the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange. The NAV for a normal trading day is released after 4:00 p.m. Eastern time (“E.T.”). For futures contracts and options traded on exchanges, USOU and USOD’s administrator (the “Administrator”) use the closing or settlement price published by the applicable exchange or, in the case of a market disruption, the last traded price before settlement. In the case of the Benchmark Oil Futures Contract, the NYMEX closing price (determined at the earlier of the close of the NYMEX or 2:30 p.m. E.T.) for the contracts traded on the NYMEX is used. Other investments’ values for purposes of determining the NAV for each of USOU and USOD, including Treasuries, cash equivalents (other than money market funds), cleared and non-cleared swaps, forwards, options and swaps are calculated by the Administrator using market quotations and market data, if available, or other information customarily used to determine the fair value of such investments as of the earlier of the close of the NYSE Arca or 4:00 p.m. E.T. Money market funds are valued at their end of day NAV.
Net Income (Loss) Per Share	Net Income (Loss) Per Share Net income (loss) per share is the difference between the per share NAV at the beginning of each period and at the end of each period. The weighted average number of shares outstanding was computed for purposes of disclosing net income (loss) per weighted average share. The weighted average shares are equal to the number of shares outstanding at the end of the period, adjusted proportionately for shares added and redeemed based on the amount of time the shares were outstanding during such period. As of December 31, 2019, USCF did not hold any shares of each of USOU and USOD.
Offering Costs	Offering Costs Offering costs incurred in connection with the registration of additional shares of any Trust Series after the initial registration of shares of such Trust Series are borne by each respective Trust Series. These costs include registration fees paid to regulatory agencies and all legal, accounting, printing and other expenses associated with such offerings. These costs are accounted for as a deferred charge and thereafter amortized to expense over twelve months on a straight-line basis or a shorter period if warranted.
Cash Equivalents	Cash Equivalents Cash equivalents include money market funds and overnight deposits or time deposits with original maturity dates of six months or less.
Reclassification	Reclassification Certain amounts in the accompanying financial statements were reclassified to conform to the current presentation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires USCF to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of the revenue and expenses during the reporting period. Actual results may differ from those estimates and assumptions.
