	NOTE 1 - ORGANIZATION AND BUSINESS
	The United States Diesel-Heating Oil Fund, LP (“UHN”), formerly, the United States Heating Oil Fund, LP was organized as a limited partnership under the laws of the state of Delaware on April 13, 2007. UHN is a commodity pool that issues limited partnership shares (“shares”) that may be purchased and sold on the NYSE Arca, Inc. (the “NYSE Arca”). Prior to November 25, 2008, UHN’s shares traded on the American Stock Exchange (the “AMEX”). UHN will continue in perpetuity, unless terminated sooner upon the occurrence of one or more events as described in its Second Amended and Restated Agreement of Limited Partnership dated as of March 1, 2013 (the “LP Agreement”). The investment objective of UHN is for the daily changes in percentage terms of its shares’ per share net asset value (“NAV”) to reflect the daily changes in percentage terms of the spot price of diesel-heating oil (also known as No. 2 fuel oil) for delivery to the New York harbor, as measured by the daily changes in the price of the futures contract for diesel-heating oil traded on the New York Mercantile Exchange (the “NYMEX”) that is the near month contract to expire, except when the near month contract is within two weeks of expiration, in which case the futures contract will be the next month contract to expire (the “Benchmark Futures Contract”), less UHN’s expenses. It is not the intent of UHN to be operated in a fashion such that the per share NAV will equal, in dollar terms, the spot price of heating oil or any particular futures contract based on heating oil. It is not the intent of UHN to be operated in a fashion such that its per share NAV will reflect the percentage change of the price of any particular futures contract as measured over a time period greater than one day. United States Commodity Funds LLC (“USCF”), the general partner of UHN, believes that it is not practical to manage the portfolio to achieve such an investment goal when investing in Futures Contracts (as defined below) and Other Diesel-Heating Oil-Related Investments (as defined below). UHN accomplishes its objective through investments in futures contracts for diesel-heating oil, crude oil, gasoline, natural gas and other petroleum-based fuels that are traded on the NYMEX, ICE Futures or other U.S. and foreign exchanges (collectively, “Futures Contracts”) and Other Diesel-Heating Oil-Related Investments such as cash-settled options on Futures Contracts, forward contracts for diesel-heating oil and over-the-counter transactions that are based on the price of diesel-heating oil, crude oil and other petroleum-based fuels, Futures Contracts and indices based on the foregoing (collectively, “Other Diesel-Heating Oil-Related Investments”). As of December 31, 2013, UHN held 39 Futures Contracts for diesel-heating oil traded on the NYMEX.
	Prior to August 1, 2012, UHN was known as United States Heating Oil Fund, LP. USCF believes that, historically, the heating oil futures contract has been used by both industry and financial participants as a way to hedge or invest in exposure to diesel fuel due to the close physical similarities between the two products. The New York Mercantile Exchange (the “NYMEX”) announced in April 2012 changes to the physical specifications of the heating oil contract which involves the reduction in the allowable amount of sulfur in heating oil down to the levels found in diesel fuel. In doing so, the NYMEX specifically referenced the desire to make the heating oil contract a “……dual-use price benchmark for both the heating oil and on-road diesel markets.” Aside from the change of the name and designated CUSIP number effective August 1, 2012, no other change was made to the Fund.
	UHN commenced investment operations on April 9, 2008 and has a fiscal year ending on December 31. USCF is responsible for the management of UHN. USCF is a member of the National Futures Association (the “NFA”) and became a commodity pool operator registered with the Commodity Futures Trading Commission (the “CFTC”) effective December 1, 2005. USCF is also the general partner of the United States Oil Fund, LP (“USO”), the United States Natural Gas Fund, LP (“UNG”), the United States 12 Month Oil Fund, LP (“USL”) and the United States Gasoline Fund, LP (“UGA”), which listed their limited partnership shares on the AMEX under the ticker symbols ”USO” on April 10, 2006, “UNG” on April 18, 2007, “USL” on December 6, 2007 and “UGA” on February 26, 2008, respectively. As a result of the acquisition of the AMEX by NYSE Euronext, each of USO’s, UNG’s, USL’s and UGA’s shares commenced trading on the NYSE Arca on November 25, 2008. USCF is also the general partner of the United States Short Oil Fund, LP (“DNO”), the United States 12 Month Natural Gas Fund, LP (“UNL”) and the United States Brent Oil Fund, LP (“BNO”), which listed their limited partnership shares on the NYSE Arca under the ticker symbols “DNO” on September 24, 2009, “UNL” on November 18, 2009 and “BNO” on June 2, 2010, respectively. USCF is also the sponsor of the United States Commodity Index Fund (“USCI”), the United States Copper Index Fund (“CPER”), the United States Agriculture Index Fund (“USAG”) and the United States Metals Index Fund (“USMI”), each a series of the United States Commodity Index Funds Trust. USCI, CPER, USAG and USMI listed their shares on the NYSE Arca under the ticker symbol “USCI” on August 10, 2010, “CPER” on November 15, 2011, “USAG” on April 13, 2012 and “USMI” on June 19, 2012, respectively. All funds listed previously are referred to collectively herein as the “Related Public Funds.” USCF previously filed registration statements to register shares of the United States Sugar Fund (“USSF”), the United States Natural Gas Double Inverse Fund (“UNGD”), the United States Gasoil Fund (“USGO”) and the United States Asian Commodities Basket Fund (“UAC”), each of which is a series of the United States Commodity Funds Trust I, and the US Golden Currency Fund (“HARD”), a series of the United States Currency Funds Trust. On December 30, 2013, USCF withdrew the registration statements for USSF, UNGD, USGO and UAC effective December 31, 2013. On January 27, 2014, USCF withdrew the registration statement for HARD. HARD was never available to the public, and at the time of withdrawal, HARD was still in the process of review by various regulatory agencies which have regulatory authority over USCF and HARD.
	Effective February 29, 2012, UHN issues shares to certain authorized purchasers (“Authorized Purchasers”) by offering baskets consisting of 50,000 shares (“Creation Baskets”) through ALPS Distributors, Inc., as the marketing agent (the “Marketing Agent”). Prior to February 29, 2012, UHN issued shares to Authorized Purchasers by offering baskets consisting of 100,000 shares through the Marketing Agent. The purchase price for a Creation Basket is based upon the NAV of a share 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.
	From July 1, 2011 through December 31, 2013 (and continuing through at least May 1, 2014), the applicable transaction fee paid by Authorized Purchasers is $350 to UHN for each order they place to create or redeem one or more baskets (“Redemption Baskets”); prior to July 1, 2011, this fee was $1,000. 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 UHN but rather at market prices quoted on such exchange.
	In April 2008, UHN initially registered 10,000,000 shares on Form S-1 with the U.S. Securities and Exchange Commission (the “SEC”). On April 9, 2008, UHN listed its shares on the AMEX under the ticker symbol “UHN”. On that day, UHN established its initial per share NAV by setting the price at $50.00 and issued 200,000 shares in exchange for $10,000,000. UHN also commenced investment operations on April 9, 2008 by purchasing Futures Contracts traded on the NYMEX based on heating oil. As of December 31, 2013, UHN had registered a total of 60,000,000 shares.

SUMMARY_OF_SIGNIFICANT_ACCOUNT

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2013
Summary Of Significant Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	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. UHN earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant at the overnight Federal Funds Rate less 32 basis points. In addition, UHN earns income on funds held at the custodian or futures commission merchant 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
	UHN is not subject to federal income taxes; each partner reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return.
	In accordance with accounting principles generally accepted in the United States of America (“GAAP”), UHN 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. UHN files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. UHN is not subject to income tax return examinations by major taxing authorities for years before 2010. 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 UHN recording a tax liability that reduces net assets. However, UHN’s 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. UHN 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, 2013.
	Creations and Redemptions
	Effective February 29, 2012, Authorized Purchasers 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. Prior to February 29, 2012, Authorized Purchasers could only purchase Creation Baskets or redeem Redemption Baskets in blocks of 100,000 shares.
	UHN receives or pays the proceeds from shares sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from Authorized Purchasers are reflected in UHN’s statements of financial condition as receivable for shares sold, and amounts payable to Authorized Purchasers upon redemption are reflected as payable for shares redeemed.
	Partnership Capital and Allocation of Partnership Income and Losses
	Profit or loss shall be allocated among the partners of UHN in proportion to the number of shares each partner holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the LP Agreement.
	Calculation of Per Share Net Asset Value
	UHN’s 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. UHN uses the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.
	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. There were no shares held by USCF at December 31, 2013.
	Offering Costs
	Offering costs incurred in connection with the registration of additional shares after the initial registration of shares are borne by UHN. 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 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.

	NOTE 3 - FEES PAID BY THE FUND AND RELATED PARTY TRANSACTIONS
	USCF Management Fee
	Under the LP Agreement, USCF is responsible for investing the assets of UHN in accordance with the objectives and policies of UHN. In addition, USCF has arranged for one or more third parties to provide administrative, custody, accounting, transfer agency and other necessary services to UHN. For these services, UHN is contractually obligated to pay USCF a fee, which is paid monthly, equal to 0.60% per annum of average daily net assets.
	Ongoing Registration Fees and Other Offering Expenses
	UHN pays all costs and expenses associated with the ongoing registration of its shares subsequent to the initial offering. These costs include registration or other fees paid to regulatory agencies in connection with the offer and sale of shares, and all legal, accounting, printing and other expenses associated with such offer and sale. For the years ended December 31, 2013, 2012 and 2011, UHN incurred $7,300, $7,320 and $7,300, respectively, in registration fees and other offering expenses.

	UHN is responsible for paying its portion of the directors’ and officers’ liability insurance for UHN and the Related Public Funds and the fees and expenses of the independent directors who also serve as audit committee members of UHN and the Related Public Funds organized as limited partnerships and, as of July 8, 2011, the Related Public Funds organized as a series of a Delaware statutory trust. UHN shares the fees and expenses on a pro rata basis with each Related Public Fund, as described above, based on the relative assets of each fund computed on a daily basis. These fees and expenses for the year ended December 31, 2013 were $555,465 for UHN and the Related Public Funds. UHN’s portion of such fees and expenses for the year ended December 31, 2013 was $1,370. These fees and expenses for the year ended December 31, 2012 were $540,586 for UHN and the Related Public Funds.

	Licensing Fees
	As discussed in Note 4 below, UHN entered into a licensing agreement with the NYMEX on May 30, 2007, as amended on October 20, 2011. Pursuant to the agreement, up through October 19, 2011, UHN and the Related Public Funds, other than BNO, USCI, CPER, USAG and USMI, paid a licensing fee that was equal to 0.04% for the first $1,000,000,000 of combined net assets of the funds and 0.02% for combined net assets above $1,000,000,000. On and after October 20, 2011, UHN and the Related Public Funds, other than BNO, USCI, CPER , USAG and USMI, pay a licensing fee that is equal to 0.015% on all net assets. During the years ended December 31, 2013, 2012 and 2011, UHN incurred $953, $1,223 and $2,040, respectively, under this arrangement.

	The fees and expenses associated with UHN’s audit expenses and tax accounting and reporting requirements are paid by UHN. These costs were approximately $85,000, $50,000 and $45,000, respectively, for each of the years ended December 31, 2013, 2012 and 2011.
	Other Expenses and Fees and Expense Waivers
	In addition to the fees described above, UHN pays all brokerage fees and other expenses in connection with the operation of UHN, excluding costs and expenses paid by USCF as outlined in Note 4 below. USCF has voluntarily agreed to pay certain expenses typically borne by UHN, to the extent that such expenses exceed 0.15% (15 basis points) of UHN’s NAV, on an annualized basis, through at least June 30, 2014. USCF has no obligation to continue such payments into subsequent periods. For the year ended December 31, 2013, USCF waived $100,808 of UHN’s expenses. This voluntary expense waiver is in addition to those amounts USCF is contractually obligated to pay as described in Note 4.

	UHN is party to a marketing agent agreement, dated as of March 10, 2008, as amended from time to time, with the Marketing Agent and USCF, whereby the Marketing Agent provides certain marketing services for UHN as outlined in the agreement. The fee of the Marketing Agent, which is borne by USCF, is equal to 0.06% on UHN’s assets up to $3 billion and 0.04% on UHN’s assets in excess of $3 billion.
	The above fee does not include the following expenses, which are also borne by USCF: the cost of placing advertisements in various periodicals; website construction and development; or the printing and production of various marketing materials.
	UHN is also party to a custodian agreement, dated March 13, 2008, as amended from time to time, with Brown Brothers Harriman & Co. (“BBH&Co.”) and USCF, whereby BBH&Co. holds investments on behalf of UHN. USCF pays the fees of the custodian, which are determined by the parties from time to time. In addition, UHN is party to an administrative agency agreement, dated February 7, 2008, as amended from time to time, with USCF and BBH&Co., whereby BBH&Co. acts as the administrative agent, transfer agent and registrar for UHN. USCF also pays the fees of BBH&Co. for its services under such agreement and such fees are determined by the parties from time to time.
	Currently, USCF pays BBH&Co. for its services, in the foregoing capacities, a minimum amount of $75,000 annually for its custody, fund accounting and fund administration services rendered to UHN and each of the Related Public Funds, as well as a $20,000 annual fee for its transfer agency services. In addition, USCF pays BBH&Co. an asset-based charge of: (a)  0.06% for the first $500 million of the Related Public Funds’ combined net assets, (b)  0.0465% for the Related Public Funds’ combined net assets greater than $500 million but less than $1 billion, and (c)  0.035% once the Related Public Funds’ combined net assets exceed $1 billion. The annual minimum amount will not apply if the asset-based charge for all accounts in the aggregate exceeds $75,000. USCF also pays transaction fees ranging from $7 to $15 per transaction.
	On October 8, 2013, UHN entered into a brokerage agreement with RBC Capital Markets, LLC (“RBC Capital” or “RBC”) to serve as UHN’s futures commission merchant (“FCM”), effective October 10, 2013. Prior to October 10, 2013, the FCM was UBS Securities LLC (“UBS Securities”). The agreements require RBC Capital and UBS Securities to provide services to UHN in connection with the purchase and sale of Futures Contracts and Other Diesel-Heating Oil-Related Investments that may be purchased and sold by or through RBC Capital and/or UBS Securities for UHN’s account. In accordance with each agreement, RBC Capital and UBS Securities charges UHN commissions of approximately $7 to 15 per round-turn trade, including applicable exchange and NFA fees for Futures Contracts and options on Futures Contracts. Such fees include those incurred when purchasing Futures Contracts and options on Futures Contracts when UHN issues shares as a result of a Creation Basket, as well as fees incurred when selling Futures Contracts and options on Futures Contracts when UHN redeems shares as a result of a Redemption Basket. Such fees are also incurred when Futures Contracts and options on Futures Contracts are purchased or redeemed for the purpose of rebalancing the portfolio. UHN also incurs commissions to brokers for the purchase and sale of Futures Contracts, Other Diesel-Heating Oil-Related Investments or short-term obligations of the United States of two years or less (“Treasuries”). During the year ended December 31, 2013, total commissions accrued to brokers amounted to $4,010. Of this amount, approximately $3,969, or 98.98% was a result of rebalancing costs and approximately $41, or 1.02% was the result of trades necessitated by creation and redemption activity. By comparison, during the year ended December 31, 2012, total commissions accrued to brokers amounted to $5,226. Of this amount, approximately $5,140, or 98.35% was a result of rebalancing costs and approximately $86, or 1.65% was the result of trades necessitated by creation and redemption activity. By comparison, during the year ended December 31, 2011, total commissions accrued to brokers amounted to $5,568. Of this amount, approximately $5,296, or 95.11% was a result of rebalancing costs and approximately $272, or 4.89% was the result of trades necessitated by creation and redemption activity. The decrease in the total commissions accrued to brokers for the year ended December 31, 2013 as compared to the year ended December 31, 2012, was primarily a result of fewer Futures Contracts held and traded during the year ended December 31, 2013, as compared to the year ended December 31, 2012. The decrease in the total commissions accrued to brokers for the year ended December 31, 2012 as compared to the year ended December 31, 2011 was primarily a function of decreased brokerage fees due to a lower number of Futures Contracts being held and traded as a result of the decrease in UHN’s total net assets and the increase in the price of Futures Contracts during the year ended December 31, 2012. As an annualized percentage of average total net assets, the figure for the year ended December 31, 2013 represents approximately 0.06% of average total net assets. By comparison, the figure for the year ended December 31, 2012 represented approximately 0.06% of average total net assets and the figure for the year ended December 31, 2011 represented approximately 0.06% of average total net assets. However, there can be no assurance that commission costs and portfolio turnover will not cause commission expenses to rise in future quarters.
	UHN and the NYMEX entered into a licensing agreement on May 30, 2007, as amended on October 20, 2011, whereby UHN was granted a non-exclusive license to use certain of the NYMEX’s settlement prices and service marks. Under the licensing agreement, UHN and the Related Public Funds, other than BNO, USCI, CPER, USAG and USMI, pay the NYMEX an asset-based fee for the license, the terms of which are described in Note 3. UHN expressly disclaims any association with the NYMEX or endorsement of UHN by the NYMEX and acknowledges that “NYMEX” and “New York Mercantile Exchange” are registered trademarks of the NYMEX.

Financial Instruments Off Balance Sheet Risks and Contingencies [Abstract]	'
Financial Instruments, Off-Balance Sheet Risks and Contingencies	'
	NOTE 5 - FINANCIAL INSTRUMENTS, OFF-BALANCE SHEET RISKS AND CONTINGENCIES
	UHN engages in the trading of futures contracts and options on futures contracts (collectively, “derivatives”). UHN is 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.
	UHN may enter into futures contracts and options on futures contracts 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.
	The purchase and sale of futures contracts and options on futures contracts require margin deposits with a FCM. Additional deposits may be necessary for any loss on contract value. The Commodity Exchange Act requires a FCM to segregate all customer transactions and assets from the FCM’s proprietary activities.
	Futures contracts 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 UHN 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.
	All of the futures contracts held by UHN were exchange-traded through December 31, 2013. The risks associated with exchange-traded contracts are generally perceived to be less than those associated with over-the-counter transactions since, in over-the-counter transactions, a party must rely solely on the credit of its respective individual counterparties. When UHN enters into non-exchange traded contracts (including Exchange for Risk or EFR transactions), it 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, if any, on the transaction. UHN has 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, UHN bears the risk of financial failure by the clearing broker.
	UHN’s cash and other property, such as Treasuries, deposited with a FCM are considered commingled with all other customer funds, subject to the FCM’s segregation requirements. In the event of a 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 a FCM could result in the complete loss of UHN’s assets posted with that FCM; however, the majority of UHN’s assets are held in investments in Treasuries, cash and/or cash equivalents with UHN’s custodian and would not be impacted by the insolvency of a FCM. The failure or insolvency of UHN’s custodian, however, could result in a substantial loss of UHN’s assets.
	USCF invests a portion of UHN’s cash in money market funds that seek to maintain a stable per share NAV. UHN is exposed to any risk of loss associated with an investment in such money market funds. As of December 31, 2013 and December 31, 2012, UHN held investments in money market funds in the amounts of $3,202,094 and $3,202,094, respectively. USCF holds 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, 2013 and December 31, 2012, UHN held cash deposits and investments in Treasuries in the amounts of $1,396,239 and $3,170,489, respectively, with the custodian and futures commission merchant. Some or all of these amounts may be subject to loss should UHN’s custodian and/or futures commission merchant cease operations.
	For derivatives, risks arise from changes in the market value of the contracts. Theoretically, UHN is 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, UHN pays or receives a premium at the outset and then bears the risk of unfavorable changes in the price of the contract underlying the option.
	UHN’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 controls and procedures. In addition, UHN has a policy of requiring review of the credit standing of each broker or counterparty with which it conducts business.
	The financial instruments held by UHN 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 Instruments

'

NOTE 8 - FAIR VALUE OF FINANCIAL INSTRUMENTS

UHN values its 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 UHN (observable inputs) and (2) UHN’s 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.

The following table summarizes the valuation of UHN’s securities at December 31, 2013 using the fair value hierarchy:

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended

Summary Of Significant Accounting Policies [Abstract]	'
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. UHN earns interest on its assets denominated in U.S. dollars on deposit with the futures commission merchant at the overnight Federal Funds Rate less 32 basis points. In addition, UHN earns income on funds held at the custodian or futures commission merchant 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
	UHN is not subject to federal income taxes; each partner reports his/her allocable share of income, gain, loss deductions or credits on his/her own income tax return.
	In accordance with accounting principles generally accepted in the United States of America (“GAAP”), UHN 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. UHN files an income tax return in the U.S. federal jurisdiction, and may file income tax returns in various U.S. states. UHN is not subject to income tax return examinations by major taxing authorities for years before 2010. 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 UHN recording a tax liability that reduces net assets. However, UHN’s 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. UHN 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, 2013.
Creations and Redemptions	'
	Creations and Redemptions
	Effective February 29, 2012, Authorized Purchasers 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. Prior to February 29, 2012, Authorized Purchasers could only purchase Creation Baskets or redeem Redemption Baskets in blocks of 100,000 shares.
	UHN receives or pays the proceeds from shares sold or redeemed within three business days after the trade date of the purchase or redemption. The amounts due from Authorized Purchasers are reflected in UHN’s statements of financial condition as receivable for shares sold, and amounts payable to Authorized Purchasers upon redemption are reflected as payable for shares redeemed.
Partnership Capital and Allocation of Partnership Income and Losses	'
	Partnership Capital and Allocation of Partnership Income and Losses
	Profit or loss shall be allocated among the partners of UHN in proportion to the number of shares each partner holds as of the close of each month. USCF may revise, alter or otherwise modify this method of allocation as described in the LP Agreement.
Calculation of Per Unit Net Asset Value	'
	Calculation of Per Share Net Asset Value
	UHN’s 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. UHN uses the closing price for the contracts on the relevant exchange on that day to determine the value of contracts held on such exchange.
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. There were no shares held by USCF at December 31, 2013.
Offering Costs	'
	Offering Costs
	Offering costs incurred in connection with the registration of additional shares after the initial registration of shares are borne by UHN. 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 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.
