Organization [Abstract]
Organization	(1) Organization The WisdomTree Continuous Commodity Index Fund (the “Fund”; “Fund” may also refer to the Fund and the Master Fund, collectively as the context requires) was formed as a Delaware statutory trust on October 27, 2006, and WisdomTree Continuous Commodity Index Master Fund (the “Master Fund”), was formed as a Delaware statutory trust on October 27, 2006. WisdomTree Commodity Services, LLC (the “Managing Owner”) serves the Fund as commodity pool operator and managing owner. Effective January 1, 2016, in accordance with the terms of a Unit Purchase Agreement dated October 29, 2015, GreenHaven LLC sold 100% of the issued and outstanding membership interest in the Managing Owner to WisdomTree Investments Inc. Following the sale, the name of the Fund was changed from “GreenHaven Continuous Commodity Index Fund” to “WisdomTree Continuous Commodity Index Fund,” the name of the Master Fund was changed from “GreenHaven Continuous Commodity Index Master Fund” to “WisdomTree Continuous Commodity Index Master Fund,” and the name of the Managing Owner was changed from “GreenHaven Commodity Services, LLC” to “WisdomTree Commodity Services, LLC.” As of January 1, 2016, the Fund’s Sub-Advisor and commodity trading advisor is GreenHaven Advisors LLC. The Fund offers common units of beneficial interest (the “Shares”). Upon inception, 50 General Units of the Fund were issued to the Managing Owner in exchange for a capital contribution of $1,500. The proceeds from the offering of Shares are invested in the Master Fund (See Note 7 for details of the procedures for creation and redemption of Shares in the Fund). The Master Fund actively trades exchange traded futures on the commodities comprising the Thomson Reuters Continuous Commodity Index (the “Index”), with a view to tracking the performance of the Index over time. The Master Fund’s Portfolio also includes United States Treasury securities and other high credit-quality short-term fixed income securities for deposit with the Master Fund’s commodity broker as margin. The Fund wholly owns the Master Fund. The Fund and Master Fund commenced investment operations on January 23, 2008 with the offering of 350,000 Shares in exchange for $10,500,000. The Fund commenced trading on the American Stock Exchange (now known as the NYSE Arca) on January 24, 2008 and, as of November 25, 2008, was listed on the NYSE Arca. For a description of the Fund’s offerings following the commencement of trading see Part II, Item 5. The Index is intended to reflect the performance of certain commodities. Through January 6, 2013, the commodities comprising the Index (the “Index Commodities”) were: corn, soybeans, wheat, live cattle, lean hogs, gold, silver, copper, cocoa, coffee, sugar, cotton, orange juice, platinum, crude oil, NY Harbor ULSD (formerly known as heating oil), and natural gas. The Index was revised on January 7, 2013 to include soybean oil and remove orange juice. The Managing Owner and the Shareholders share in any profits and losses attributable to the Fund in proportion to the percentage interest owned by each. The Managing Owner, the Funds, and the Master Fund retain the services of third party service providers for the ongoing operations of the Fund and the Master Fund (See Note (2)).

Summary of Significant Accounti

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(3) Summary of Significant Accounting Policies (a) Use of Estimates The preparation of the financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ from those estimates. (b) Cash Held by Broker The Fund defines cash held by broker to be cash and highly liquid investments with remaining maturities of three months or less when acquired. MS&Co. allows the Master Fund to apply its Treasury Bill portfolio towards its initial margin requirement for the Master Fund’s futures positions, hence all cash held by broker is unrestricted cash. The cash and Treasury bill positions are held in segregated accounts at MS&Co. and are not insured by the Federal Deposit Insurance Corporation. (c) United States Treasury Obligations The Master Fund records purchases and sales of United States Treasury Obligations on a trade date basis. These holdings are marked to market based on market quotations from broker-dealers or independent service providers. The Master Fund holds United States Treasury Obligations for deposit with the Master Fund’s commodity broker as margin and for trading and holding against initial margin of the open futures contracts. Interest income is recognized on an accrual basis when earned. Premiums and discounts are amortized or accreted over the life of the United States Treasury Obligations. (d) Income Taxes The Fund and Master Fund are classified as a grantor trust and a partnership respectively, for U.S. federal income tax purposes. Accordingly, neither the Fund nor the Master Fund is subject to U.S. federal, state, or local income taxes. No provision for federal, state, or local income taxes has been made in the accompanying consolidated financial statements, as investors are individually liable for income taxes, if any, on their allocable share of the Fund’s share of the Master Fund’s income, gain, loss, deductions and other items. The Fund accounts for uncertainty in income taxes pursuant to the applicable accounting standard, which provides measurement, presentation and disclosure guidance related to uncertain tax positions. The guidance addresses how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under this topic, the Fund recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. Management’s reassessment of the Fund’s tax positions has not had a material impact on the Fund’s financial condition, results of operations or liquidity in any year presented. (e) Futures Contracts The Master Fund purchases and holds commodity futures contracts for investment purposes. These contracts are recorded on a trade date basis and open contracts are valued daily at settlement prices provided by the relevant exchanges. In the consolidated statements of financial condition, futures contracts are presented at their published settlement prices on the last business day of the period, in accordance with the fair value accounting standard. Since these contracts are actively traded in markets that are directly observable and which provide readily available price quotes, their market value is deemed to be their fair value under the fair value accounting standard. (See Note 4 – Fair Value Measurements) However, when market closing prices are not available, the Managing Owner may value an asset of the Master Fund pursuant to such other principles as the Managing Owner deems fair and equitable provided such principles are consistent with the fair value accounting standard. Realized gains (losses) and changes in unrealized appreciation (depreciation) on open positions are determined on a specific identification basis and recognized in the consolidated statements of income and expenses in the period in which the contract is closed or the changes occur, respectively. (f) Basis of Presentation and Consolidation All of the capital raised by the Fund is used to purchase common units of beneficial interest in the Master Fund. The financial statement balances of the Master Fund are consolidated with the Fund’s financial statement balances and all significant inter-company balances and transactions are eliminated. Separate financial statements of the Master Fund are presented to comply with SEC reporting requirements as the Master Fund is a separate SEC registrant. (g) Subsequent Events For purposes of disclosure in the consolidated financial statements, the Fund has evaluated events occurring between the year ended December 31, 2015 and when the financial statements were issued. Subsequent to December 31, 2015, 0 Limited Shares were created and 750,000 Limited Shares were redeemed resulting in 11,350,000 Limited Shares outstanding. Effective January 1, 2016, in accordance with the terms of a Unit Purchase Agreement dated October 29, 2015, GreenHaven LLC sold 100% of the issued and outstanding membership interest in the Managing Owner to WisdomTree Investments Inc. Following the sale, the name of the Fund was changed from “GreenHaven Continuous Commodity Index Fund” to “WisdomTree Continuous Commodity Index Fund,” the name of the Master Fund was changed from “GreenHaven Continuous Commodity Index Master Fund” to “WisdomTree Continuous Commodity Index Master Fund,” and the name of the Managing Owner was changed from “GreenHaven Commodity Services, LLC” to “WisdomTree Commodity Services, LLC.” The foregoing sale resulted in no accounting impact for the financial reporting period for the year ended December 31, 2015. Concurrent with the effectiveness of the sale, the audit committee of the Managing Owner resigned. Other than these events, the evaluation did not result in any subsequent events that necessitated disclosures and/or adjustments.

Fair Value Disclosures [Abstract]
Fair Value Measurements	(4) Fair Value Measurements The guidance for fair value measurements establishes the authoritative definition for fair value, sets out a framework for measuring fair value and outlines the required disclosures regarding fair value measurements. Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. The Fund uses a three-tier fair value hierarchy based upon observable and non-observable inputs as follows: Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the reporting entity can access at the measurement date. Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 — Unobservable inputs for the asset or liability. The inputs or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities. The assets of the Fund are either exchange-traded securities or government securities that are valued using dealer and broker quotations or other inputs that are observable or can be corroborated by observable market data. A summary of the Fund’s assets and liabilities at fair value as of December 31, 2015, classified according to the levels used to value them, is as follows: Assets Quoted Other Significant Totals U.S. Treasuries $ - $ 149,980,000 $ - $ 149,980,000 Commodity Futures Contracts (8,705,967 ) - - (8,705,967 ) Total $ (8,705,967 ) $ 149,980,000 $ - $ 141,274,033 There were no transfers between Level 1 and Level 2 for the Fund during the year ended December 31, 2015. The Fund did not hold any Level 3 securities during the year ended December 31, 2015. A summary of the Fund’s assets and liabilities at fair value as of December 31, 2014, classified according to the levels used to value them, are as follows: Assets Quoted Other Significant Totals U.S. Treasuries $ - $ 199,995,250 $ - $ 199,995,250 Commodity Futures Contracts (27,249,076 ) - - (27,249,076 ) Total $ (27,249,076 ) $ 199,995,250 $ - $ 172,746,174 There were no transfers between Level 1 and Level 2 for the Fund during the year ended December 31, 2014. The Fund did not hold any Level 3 securities during the year ended December 31, 2014.

Financial Instrument Risk

Financial Instrument Risk	12 Months Ended
	Dec. 31, 2015
Investments, All Other Investments [Abstract]
Financial Instrument Risk	(6) Financial Instrument Risk In the normal course of its business, the Fund is party to financial instruments with off-balance sheet risk. The term “off-balance sheet risk” refers to an unrecorded potential liability that, even though it does not appear on the balance sheet, may result in a future obligation or loss. The financial instruments used by the Fund are commodity futures, whose values are based upon an underlying asset and generally represent future commitments that have a reasonable possibility to be settled in cash or through physical delivery. These instruments are traded on an exchange and are standardized contracts. Market risk is the potential for changes in the value of the financial instruments traded by the Fund due to market changes, including fluctuations in commodity prices. In entering into these contracts, there exists a market risk that such contracts may be significantly influenced by conditions, resulting in such contracts being less valuable. If the markets should move against all of the futures interest positions at the same time, and the Managing Owner was unable to offset such positions, the Fund could experience substantial losses. Credit risk is the possibility that a loss may occur due to the failure of an exchange clearinghouse to perform according to the terms of a contract. Credit risk with respect to exchange-traded instruments is reduced to the extent that an exchange or clearing organization acts as counterparty to the transactions. The Fund’s risk of loss in the event of counterparty default is typically limited to the amounts recognized in the statement of financial condition and not represented by the contract or notional amounts of the instruments. The Fund and the Master Fund have not utilized, nor do they expect to utilize in the future, special purpose entities to facilitate off-balance sheet financing arrangements and have no loan guarantee arrangements or off-balance sheet arrangements of any kind other than agreements entered into in the normal course of business.

Share Creations And Redemptions [Abstract]
Share Creations and Redemptions	(7) Share Creations and Redemptions (a) Creation of shares General Determination of Required Payment Because orders to purchase Baskets must be placed by 10:00 a.m., New York time, but the total payment required to create a Basket during the continuous offering period will not be determined until 4:00 p.m., New York time, on the date the purchase order is received, Authorized Participants will not know the total amount of the payment required to create a Basket at the time they submit an irrevocable purchase order for the Basket. The Fund’s Net Asset Value and the total amount of the payment required to create a Basket could rise or fall substantially between the time an irrevocable purchase order is submitted and the time the amount of the purchase price in respect thereof is determined. Rejection of Purchase Orders (i) it determines that the purchase order is not in proper form; (ii) the Managing Owner believes that the purchase order would have adverse tax consequences to the Fund or its Shareholders; or (iii) circumstances outside the control of the Managing Owner or the Distributor make it, for all practical purposes, not feasible to process creations of Baskets. The Distributor and the Managing Owner will not be liable for the rejection of any purchase order. (b) Redemption of Shares Redemption Procedures General By placing a redemption order, an Authorized Participant agrees to deliver the Baskets to be redeemed through DTC’s book-entry system to the Fund not later than 12:00pm, New York time, on the business day immediately following the redemption order date. By placing a redemption order, and prior to receipt of the redemption proceeds, an Authorized Participant’s DTC account will be charged the non-refundable transaction fee due for the redemption order. Determination of Required Payment Delivery of Redemption Proceeds Suspension or Rejection of Redemption Orders A redemption order may be rejected if the order is not in proper form as described in the order form and/or Participant Agreement or if the fulfillment of the order, in the opinion of its counsel, might be unlawful.

The Fund’s brokerage commissions and fees and routine operational, administrative and other ordinary expenses are accrued at a rate of 0.20% per annum in the aggregate. Of the amounts so accrued, the Fund first pays brokerage fees, and secondly, from the remainder of the amounts so accrued, reimburses the Managing Owner for the Fund’s routine operational, administrative and other ordinary expenses paid by the Managing Owner.

No provision for federal, state, or local income taxes has been made in the accompanying consolidated financial statements, as investors are individually liable for income taxes, if any, on their allocable share of the Fund’s share of the Master Fund’s income, gain, loss, deductions and other items. The Fund accounts for uncertainty in income taxes pursuant to the applicable accounting standard, which provides measurement, presentation and disclosure guidance related to uncertain tax positions. The guidance addresses how tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under this topic, the Fund recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate resolution. Management’s reassessment of the Fund’s tax positions has not had a material impact on the Fund’s financial condition, results of operations or liquidity in any year presented.
Futures Contracts	(e) Futures Contracts The Master Fund purchases and holds commodity futures contracts for investment purposes. These contracts are recorded on a trade date basis and open contracts are valued daily at settlement prices provided by the relevant exchanges. In the consolidated statements of financial condition, futures contracts are presented at their published settlement prices on the last business day of the period, in accordance with the fair value accounting standard. Since these contracts are actively traded in markets that are directly observable and which provide readily available price quotes, their market value is deemed to be their fair value under the fair value accounting standard. (See Note 4 – Fair Value Measurements) However, when market closing prices are not available, the Managing Owner may value an asset of the Master Fund pursuant to such other principles as the Managing Owner deems fair and equitable provided such principles are consistent with the fair value accounting standard. Realized gains (losses) and changes in unrealized appreciation (depreciation) on open positions are determined on a specific identification basis and recognized in the consolidated statements of income and expenses in the period in which the contract is closed or the changes occur, respectively.
Basis of Presentation and Consolidation	(f) Basis of Presentation and Consolidation All of the capital raised by the Fund is used to purchase common units of beneficial interest in the Master Fund. The financial statement balances of the Master Fund are consolidated with the Fund’s financial statement balances and all significant inter-company balances and transactions are eliminated. Separate financial statements of the Master Fund are presented to comply with SEC reporting requirements as the Master Fund is a separate SEC registrant.
Subsequent Events	(g) Subsequent Events For purposes of disclosure in the consolidated financial statements, the Fund has evaluated events occurring between the year ended December 31, 2015 and when the financial statements were issued. Subsequent to December 31, 2015, 0 Limited Shares were created and 750,000 Limited Shares were redeemed resulting in 11,350,000 Limited Shares outstanding. Effective January 1, 2016, in accordance with the terms of a Unit Purchase Agreement dated October 29, 2015, GreenHaven LLC sold 100% of the issued and outstanding membership interest in the Managing Owner to WisdomTree Investments Inc. Following the sale, the name of the Fund was changed from “GreenHaven Continuous Commodity Index Fund” to “WisdomTree Continuous Commodity Index Fund,” the name of the Master Fund was changed from “GreenHaven Continuous Commodity Index Master Fund” to “WisdomTree Continuous Commodity Index Master Fund,” and the name of the Managing Owner was changed from “GreenHaven Commodity Services, LLC” to “WisdomTree Commodity Services, LLC.” The foregoing sale resulted in no accounting impact for the financial reporting period for the year ended December 31, 2015. Concurrent with the effectiveness of the sale, the audit committee of the Managing Owner resigned. Other than these events, the evaluation did not result in any subsequent events that necessitated disclosures and/or adjustments.
