Accounting Policies [Abstract]
Organization	1. Organization: Emerging CTA Portfolio L.P. (the “Partnership”) is a limited partnership that was organized on July 7, 2003 under the partnership laws of the State of New York. The objective of the Partnership is to achieve capital appreciation through the allocation of assets to early-stage commodity trading advisors or established advisors employing early-stage strategies, which engage, directly and indirectly through investments in the Funds (defined below), in speculative trading of a diversified portfolio of commodity interests, including futures, option on futures, forward, option on forward, spot and swap contracts, cash commodities and any other rights or interest pertaining thereto. The Partnership may also enter into swap and other derivative transactions directly and through its investments in the Funds with the approval of the General Partner (defined below). The sectors traded include currencies, livestock, lumber, energy, grains, metals, indices, softs and U.S. and non-U.S. interest rates. The commodity interests that are traded by the Partnership and the Funds are volatile and involve a high degree of market risk. The General Partner may also determine to invest up to all of the Partnership’s assets in United States (“U.S”) Treasury bills and/or money market mutual funds, including money market mutual funds managed by Morgan Stanley or its affiliates. Between December 1, 2003 (commencement of the offering period) and August 5, 2004, 20,872 units of partnership interest in the Partnership (“Redeemable Units”) were sold at $1,000 per Redeemable Unit. The proceeds of the initial offering were held in an escrow account until August 6, 2004, at which time they were remitted to the Partnership for trading. The Partnership privately and continuously offers Redeemable Units in the Partnership to qualified investors. There is no maximum number of Redeemable Units that may be sold by the Partnership. Ceres Managed Futures LLC, a Delaware limited liability company, acts as the general partner (the “General Partner”) and commodity pool operator of the Partnership. The General Partner is wholly owned by Morgan Stanley Smith Barney Holdings LLC (“MSSB Holdings”). MSSB Holdings is ultimately owned by Morgan Stanley. Morgan Stanley is a publicly held company whose shares are listed on the New York Stock Exchange. Morgan Stanley is engaged in various financial services and other businesses. Prior to June 28, 2013, Morgan Stanley indirectly owned a majority equity interest in MSSB Holdings and Citigroup Inc. indirectly owned a minority equity interest in MSSB Holdings. Prior to July 31, 2009, the date as of which MSSB Holdings became its owner, the General Partner was wholly owned by Citigroup Financial Products Inc., a wholly owned subsidiary of Citigroup Global Markets Holdings Inc., the sole owner of which is Citigroup Inc. As of September 1, 2011, the Partnership began offering three classes of limited partnership interests: Class A Redeemable Units, Class D Redeemable Units and Class Z Redeemable Units; each of which will be referred to as a “Class” and collectively referred to as the “Classes.” All Redeemable Units issued prior to September 1, 2011 were deemed “Class A Redeemable Units.” The rights, liabilities, risks, and fees associated with investment in the Class A Redeemable Units were not changed. Class A Redeemable Units and Class D Redeemable Units are available to taxable U.S. individuals and institutions, as well as U.S. tax exempt individuals and institutions. Class Z Redeemable Units are offered to certain employees of Morgan Stanley and its subsidiaries (and their family members). The Class of Redeemable Units that a limited partner of the Partnership (each a “Limited Partner”) receives upon subscription will generally depend upon the amount invested in the Partnership or the status of the Limited Partner, although the General Partner may determine to offer a particular Class of Redeemable Units to investors at its discretion. As of March 31, 2016, there were no Redeemable Units outstanding in Class D or Class Z. All trading decisions are made for the Partnership by its trading advisors (the “Advisors”) either directly, through individually managed accounts, or indirectly, through investments in other collective investment vehicles. As of the close of business on March 31, 2016, The Cambridge Strategy (Asset Management) Limited (“Cambridge”), Centurion Investment Management, LLC (“Centurion”), Perella Weinberg Partners Capital Management LP (“Perella”), SECOR Capital Advisors, LP (“SECOR”) and Willowbridge Associates Inc. (“Willowbridge”) served as the Partnership’s major commodity trading advisors. Prior to the termination of its management agreement effective September 30, 2015, Blackwater Capital Management, LLC (“Blackwater”) also served as one of the Partnership’s major commodity trading advisors. In addition, the General Partner may allocate the Partnership’s assets to additional non-major trading advisors (i.e. commodity trading advisors intended to be allocated less than 10% of the Partnership’s assets). Information about advisors allocated less than 10% of the Partnership’s assets may not be disclosed. The General Partner may also allocate less than 10% of the Partnership’s assets to a new trading advisor or another trading program of a current Advisor. The Advisors are not affiliated with one another, are not affiliated with the General Partner or Morgan Stanley & Co. LLC (“MS&Co.”), and are not responsible for the organization or operation of the Partnership. References herein to the “Advisors” may also include, as relevant, references to Blackwater. During the reporting periods ended March 31, 2016 and 2015, the Partnership’s/Funds’ commodity broker was MS&Co., a registered futures commission merchant. The Partnership/Funds also deposit a portion of their cash in non-trading accounts at JPMorgan Chase Bank, N.A. The assets allocated to Centurion for trading are traded directly pursuant to Centurion’s Short Term Systemic Strategy Program. Since July 1, 2015, the assets allocated to Perella have been traded directly pursuant to a variation of the program traded by PWP Global Macro Master Fund L.P. Cambridge Master Fund L.P. (“Cambridge Master”), CMF Willowbridge Master Fund L.P. (“Willowbridge Master”) and SECOR Master Fund L.P (“SECOR Master”) (together with Cambridge Master and Willowbridge Master, the “Funds”) have entered into a futures account agreement with MS&Co. and commenced trading through accounts at MS&Co. PGM Master Fund L.P. (“PGM Master”) (prior to its liquidation on June 30, 2015) and Blackwater Master Fund L.P. (“Blackwater Master”) (prior to its liquidation on September 30, 2015) also entered into a futures brokerage account agreement with MS&Co. Cambridge Master has also, and PGM Master had, entered into a foreign exchange prime brokerage agreement with MS&Co. References to “Funds” included in this report may include, as relevant, PGM Master and Blackwater Master. The Partnership has also entered into a futures brokerage account agreement with MS&Co. The Partnership, directly and through its investment in the Funds, pays MS&Co. (or will reimburse MS&Co. if previously paid) its allocable share of all trading fees for the clearing and, where applicable, execution of transactions as well as exchange, clearing, user, give-up, floor brokerage and National Futures Association fees (collectively, the “clearing fees”). The Partnership has entered into a selling agreement with Morgan Stanley Smith Barney LLC, doing business as Morgan Stanley Wealth Management (“Morgan Stanley Wealth Management”) (as amended, the “Selling Agreement”). Pursuant to the Selling Agreement, Morgan Stanley Wealth Management receives a selling agent fee equal to (i) 2.0% per year of adjusted month-end net assets for Class A Redeemable Units and (ii) 0.75% per year of adjusted month-end net assets for Class D Redeemable Units. The selling agent fee received by Morgan Stanley Wealth Management is shared with the properly registered/exempted financial advisors of Morgan Stanley Wealth Management who sell Redeemable Units in the Partnership. Class Z Redeemable Units are not subject to a selling agent fee. The General Partner and each Limited Partner share in the profits and losses of the Partnership in proportion to the amount of Partnership interest owned by each, except that no Limited Partner is liable for obligations of the Partnership in excess of its capital contribution and profits, if any, net of distributions or redemptions and losses, if any. In July 2015, the General Partner delegated certain administrative functions to SS&C Technologies, Inc., a Delaware corporation, currently doing business as SS&C GlobeOp (the “Administrator”). Pursuant to a master services agreement, the Administrator furnishes certain administrative, accounting, regulatory, reporting, tax and other services as agreed from time to time. In addition, the Administrator maintains certain books and records of the Partnership. The costs of retaining the Administrator are allocated among the pools operated by the General Partner, including the Partnership.

Accounting Policies [Abstract]
Basis of Presentation and Summary of Significant Accounting Policies	2. Basis of Presentation and Summary of Significant Accounting Policies: The accompanying financial statements and accompanying notes are unaudited but, in the opinion of the General Partner, include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Partnership’s financial condition at March 31, 2016 and December 31, 2015, and the results of its operations and changes in partners’ capital for the three months ended March 31, 2016 and 2015. These financial statements present the results of interim periods and do not include all disclosures normally provided in annual financial statements. These financial statements should be read together with the financial statements and notes included in the Partnership’s Annual Report on Form 10-K (the “Form 10-K”) filed with the Securities and Exchange Commission (the “SEC”) for the year ended December 31, 2015. The December 31, 2015 information has been derived from the audited financial statements as of and for the year ended December 31, 2015. The preparation of financial statements and accompanying notes in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires the General Partner to make estimates and assumptions that affect the reported amounts of assets and liabilities, income and expenses, and related disclosures of contingent assets and liabilities in the financial statements and accompanying notes.

Trading Activities	4. Trading Activities: The Partnership was formed for the purpose of trading contracts in a variety of commodity interests, including derivative financial instruments and derivative commodity instruments. The results of the Partnership’s trading activities are shown in the Statements of Income and Expenses and Changes in Partners’ Capital. The Partnership also invests its assets through a “master/feeder” structure. The Partnership’s pro-rata share of the results of the Funds’ trading activities is shown in the Statements of Income and Expenses and Changes in Partners’ Capital. The futures brokerage account agreements with MS&Co. give the Partnership and the Funds the legal right to net unrealized gains and losses on open futures, forward and option contracts on the Statements of Financial Condition. The Partnership and the Funds net, for financial reporting purposes, the unrealized gains and losses on open futures, forward and option contracts on the Statements of Financial Condition, as the criteria under ASC 210-20, “ Balance Sheet, All of the commodity interests owned by the Partnership are held for trading purposes. All of the commodity interests owned by the Funds are held for trading purposes. The monthly average number of futures contracts traded directly by the Partnership during the three months ended March 31, 2016 and 2015 were 2,960 and 94, respectively. The monthly average number of option contracts traded directly by the Partnership during the three months ended March 31, 2016 and 2015 were 0 and 246, respectively. The monthly average notional value of currency forward contracts traded directly by the Partnership during the three months ended March 31, 2016 and 2015 were $23,997,961 and $0, respectively. Trading and transaction fees are based on the number of trades executed by the Advisors and the Partnership’s percentage ownership of each respective Fund. All clearing fees paid to MS&Co. are borne directly by the Partnership for its direct trading and also by the Funds, which are then allocated to the Funds’ limited partners, including the Partnership. The following tables summarize the gross and net amounts recognized relating to assets and liabilities of the Partnership’s derivatives and their offsetting subject to master netting arrangements or similar agreements as of March 31, 2016 and December 31, 2015, respectively.

There is no collateral posted by MS&Co. and as such, in the event of default by MS&Co., the Partnership is exposed to the amount shown in the Statements of Financial Condition. In the case of exchange-traded contracts, the Partnership’s exposure to counterparty risk may be reduced since the exchange’s clearinghouse interposes its credit between buyer and seller and the clearinghouse’s guarantee fund may be available in the event of a default.

Fair Value Disclosures [Abstract]
Fair Value Measurements	5. Fair Value Measurements: Partnership’s and the Funds’ Fair Value Measurements. The fair value of exchange-traded futures, option and forward contracts is determined by the various futures exchanges, and reflects the settlement price for each contract as of the close of business on the last business day of the reporting period. The fair value of foreign currency forward contracts is extrapolated on a forward basis from the spot prices quoted as of approximately 3:00 P.M. (E.T.) on the last business day of the reporting period from various exchanges. The fair value of non-exchange-traded foreign currency option contracts is calculated by applying an industry standard model application for options valuation of foreign currency options, using as inputs the spot prices, interest rates, and option implied volatilities quoted as of approximately 3:00 P.M. (E.T.) on the last business day of the reporting period. U.S. Treasury bills are valued at the last available bid price received from independent pricing services as of the close of the last business day of the reporting period. The Partnership and the Funds consider prices for exchange-traded commodity futures, forward, swap and option contracts to be based on unadjusted quoted prices in active markets for identical assets and liabilities (Level 1). The values of the U.S. Treasury bills, non-exchange-traded forward, swap and certain option contracts for which market quotations are not readily available are priced by broker quotes or pricing services that derive fair values for those assets and liabilities from observable inputs (Level 2). As of March 31, 2016 and December 31, 2015 and for the periods ended March 31, 2016 and 2015, the Partnership and the Funds did not hold any derivative instruments that were priced at fair value using unobservable inputs through the application of the General Partner’s assumptions and internal valuation pricing models (Level 3). Transfers between levels are recognized at the end of the reporting period. During the reporting periods, there were no transfers of assets or liabilities between Level 1 and Level 2. March 31, 2016 Total Level 1 Level 2 Level 3 Assets U.S. Treasury bills $ 7,998,109 $ - $ 7,998,109 $ - Futures 562,137 562,137 - - Forwards 393,373 - 393,373 - Total assets $ 8,953,619 $ 562,137 $ 8,391,482 $ - Liabilities Futures $ 491,881 $ 491,881 $ - $ - Forwards 281,378 - 281,378 - Total liabilities $ 773,259 $ 491,881 $ 281,378 $ - December 31, 2015 Total Level 1 Level 2 Level 3 Assets U.S. Treasury bills $ 11,248,588 $ - $ 11,248,588 $ - Futures 1,789,359 1,789,359 - - Forwards 422,969 - 422,969 - Total assets $ 13,460,916 $ 1,789,359 $ 11,671,557 $ - Liabilities Futures $ 1,643,225 $ 1,643,225 $ - $ - Forwards 1,101,321 - 1,101,321 - Total liabilities $ 2,744,546 $ 1,643,225 $ 1,101,321 $ -

Financial Instrument Risks

Risks and Uncertainties [Abstract]
Financial Instrument Risks	7. Financial Instrument Risks: In the normal course of business, the Partnership and the Funds are party to financial instruments with off-balance sheet risk, including derivative financial instruments and derivative commodity instruments. These financial instruments may include futures, forwards, options and swaps, whose values are based upon an underlying asset, index, or reference rate, and generally represent future commitments to exchange currencies or cash balances, or to purchase or sell other financial instruments at specific terms at specified future dates, or, in the case of derivative commodity instruments, to have a reasonable possibility to be settled in cash, through physical delivery or with another financial instrument. These instruments may be traded on an exchange, a swap execution facility or over-the-counter (“OTC”). Exchange-traded instruments include futures and certain standardized forward, swap and option contracts. Certain swap contracts may also be traded on a swap execution facility or OTC. OTC contracts are negotiated between contracting parties and also include certain forward and option contracts. Each of these instruments is subject to various risks similar to those related to the underlying financial instruments, including market and credit risk. In general, the risks associated with OTC contracts are greater than those associated with exchange-traded instruments because of the greater risk of default by the counterparty to an OTC contract. The General Partner estimates that at any given time approximately 49.6% to 73.5% of the Partnership’s/Funds’ contracts are traded OTC. Futures Contracts. Forward Foreign Currency Contracts. London Metals Exchange Forward Contracts. Options. The Partnership and the Funds do not isolate the portion of the results of operations arising from the effect of changes in foreign exchange rates on investments from fluctuations from changes in market prices of investments held. Such fluctuations are included in total trading results in the Partnership’s/Funds’ Statements of Income and Expenses and Changes in Partners’ Capital. Market risk is the potential for changes in the value of the financial instruments traded by the Partnership/Funds due to market changes, including interest and foreign exchange rate movements and fluctuations in commodity or security prices. Market risk is directly impacted by the volatility and liquidity in the markets in which the related underlying assets are traded. The Partnership and the Funds are exposed to a market risk equal to the value of futures and forward contracts purchased and unlimited liability on such contracts sold short. Credit risk is the possibility that a loss may occur due to the failure of a counterparty to perform according to the terms of a contract. The Partnership’s/Funds’ risk of loss in the event of counterparty default is typically limited to the amounts recognized in the Statements of Financial Condition and is not represented by the contract or notional amounts of the instruments. The Partnership’s/Funds’ risk of loss is reduced through the use of legally enforceable master netting agreements with counterparties that permit the Partnership/Funds to offset unrealized gains and losses and other assets and liabilities with such counterparties upon the occurrence of certain events. The Partnership/Funds have credit risk and concentration risk, as MS&Co. or its affiliates are the sole counterparties or brokers with respect to the Partnership’s/Funds’ assets. Credit risk with respect to exchange-traded instruments is reduced to the extent that, through MS&Co. or its affiliates, the Partnership’s/Funds’ counterparty is an exchange or clearing organization. As both a buyer and seller of options, the Partnership/Funds 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. Written options expose the Partnership/Funds to potentially unlimited liability; for purchased options, the risk of loss is limited to the premiums paid. Certain written put options permit cash settlement and do not require the option holder to own the reference asset. The Partnership/Funds do not consider these contracts to be guarantees. The General Partner monitors and attempts to control the Partnership’s/Funds’ risk exposure on a daily basis through financial, credit and risk management monitoring systems, and accordingly, believes that it has effective procedures for evaluating and limiting the credit and market risks to which the Partnership/Funds may be subject. These monitoring systems generally allow the General Partner to statistically analyze actual trading results with risk-adjusted performance indicators and correlation statistics. In addition, online monitoring systems provide account analysis of futures, forward and option contracts by sector, margin requirements, gain and loss transactions and collateral positions. The majority of these instruments mature within one year of the inception date. However, due to the nature of the Partnership’s/Funds’ business, these instruments may not be held to maturity. The risk to the Limited Partners that have purchased Redeemable Units is limited to the amount of their share of the Partnership’s net assets and undistributed profits. The limited liability is a result of the organization of the Partnership as a limited partnership under New York law.

There is no collateral posted by MS&Co. and as such, in the event of default by MS&Co., the Partnership is exposed to the amount shown in the Statements of Financial Condition. In the case of exchange-traded contracts, the Partnership’s exposure to counterparty risk may be reduced since the exchange’s clearinghouse interposes its credit between buyer and seller and the clearinghouse’s guarantee fund may be available in the event of a default.
