Certain features of the FIX Protocol that were implemented in earlier versions of the FIX Protocol specification, have been replaced by a different approach.  Such features have been labeled as "Deprecated" throughout the FIX Specification document.  This means that feature is being phased out, systems that implement the FIX Protocol should be adjusted to use the new, supported approach, and the next version of the FIX Specification will remove the feature altogether.

The rationale behind deprecating a feature is based upon either:

  • Actual use and implementation of the feature identified major shortcomings necessitating a re-design.
  • Additional business requirements have been identified which the feature is unable to expand and properly support in its present form.

The new, supported approach for each deprecated feature is identified below:

1. Deprecated Field: TotalAccruedInterestAmt (tag 540)  [deprecated in FIX 4.4]

The TotalAccruedInterestAmt <540> field introduced in FIX 4.3 has been replaced by the FIX 4.4-introduced AllocAccruedInterestAmt <742> field for the allocation-level value. Note that AccruedInterestAmt <159> represents the block-level (total). Affects Allocation messaging.

2. Deprecated the use of SettlCurrAmt (119) and SettlCurrency (120) fields within Allocation messaging NoAllocs repeating group [deprecated in FIX 4.4]

AllocSettlCurrAmt <737> and AllocSettlCurrency <736> fields should be used instead of SettlCurrAmt <119> and SettlCurrency <120> within the NoAllocs <78> repeating group.    Affects Allocation messaging.

3. Deprecated Instrument-affiliated "RedemptionDate" Fields: RedemptionDate (240), UnderlyingRedemptionDate (247), and LegRedemptionDate (254). [deprecated in FIX 4.4]

Deprecated RedemptionDate <240> from <Instrument>, UnderlyingRedemptionDate <247> from <UnderlyingInstrument>, and LegRedemptionDate <254> from <InstrumentLeg>.

YieldRedemptionDate <696> in <YieldData> component block should be used instead.

4. Deprecated usage of the Settlement Instruction message where used to refer to an allocation message [deprecated in FIX 4.4]

The main body of the Settlement Instruction (now a component block) has been added to the allocation and confirmation messages (Allocation Instruction, Allocation Report and Confirmation).

5. Deprecated various FIX 4.3-introduced "Repo" Fields  [deprecated in FIX 4.4]

Deprecated the following fields from <Instrument>, <UnderlyingInstrument>, and <InstrumentLeg> component blocks:  RepoCollateralSecurityType <239>, RepurchaseTerm <226>, RepurchaseRate <227>, UnderlyingRepoCollateralSecurityType <243>, UnderlyingRepurchaseTerm <244>, UnderlyingRepurchaseRate <245>, LegRepoCollateralSecurityType <250>, LegRepurchaseTerm <251>, LegRepurchaseRate <252>. The RepoCollateralSecurityType <239> field is satisfied with UnderlyingSecurityType <310>, RepurchaseTerm <226> by TerminationType <788>, RepurchaseRate <227> by Price <44>.  The corresponding Underlying... and Leg... equivalents have no meaning.  FIX 4.4 introduced significant enhancements to support Product="Financing" (e.g. Repos).

6. Deprecated "UST" and "USTB" values from the SecurityType (tag 167) field  [deprecated in FIX 4.4]

Mapping of the deprecated SecurityType <167> field's values is as follows:

Deprecated Value within SecurityType (167) field SecurityType (167)
UST US Treasury Note TNOTE US Treasury Note
USTB US Treasury Bill TBILL US Treasury Bill

7. Deprecated LegQty (tag 687) from certain message types [deprecated in FIX 5.0]

Deprecated LegQty <687> from the following message types: QuoteRequest <R>, QuoteResponse <AJ>, QuoteRequestReject <AG>, Quote <S>, QuoteStatusReport <AI>, NewOrderMultileg <AB>, and ExecutionReport <8>.

The LegOrderQty <685> should be used instead to convey the order quantity at the leg level. In an Execution Report the LegOrderQty is used to echo back the order quantity from the order submission.

8. Deprecated TargetStrategyParameters (848) and ParticipationRate (849) [deprecated in FIX 5.0]

Deprecated TargetStrategyParameters <848> and ParticipationRate <849> from the following message types: NewOrderSingle <D>, NewOrderMultileg <AB>, OrderCancelReplaceRequest <G>, MultilegOrderCancelReplaceRequest <AC>, ExecutionReport <8>, NewOrderCross <s>, CrossOrderCancelReplaceRequest <t>, NewOrderList <E>

The NoStrategyParameters <957> repeating group is used instead to convey target strategy parameters and values. See Volume 7 - "PRODUCT: EQUITIES" section for additional usage.

9. Deprecated SecondaryTradeReportID (818) and SecondaryTradeReportRefID (881) [deprecated in FIX 5.0]

Deprecated SecondaryTradeReportID <818> and SecondaryTradeReportRefID <881> from the Trade Capture Report messages. These fields are no longer used.

10. Deprecated MaxFloor (111) and MaxShow (210) [deprecated in FIX 5.0]

Deprecated MaxFloor <111> and MaxShow <210> from messages. They are replaced with DisplayQty <1138> and SecondaryDisplayQty <1082>, respectively, in the <DisplayInstruction> component block.

11. Deprecated OddLot (575) [deprecated in FIX 5.0]

Deprecated OddLot <575> and replaced its usage with LotType <1093> which allows for identifying whether the lot size is an odd lot, round lot, or block lot.

12. Deprecated enum values from ExecInst (18) [deprecated in FIX 5.0]

The following enum values are deprecated from ExecInst <18>:

L — Last Peg
M — Mid price Peg
O — Opening peg
P — Market Peg
R — Primary peg
T — Fixed peg to local best bid/offer at time of order
W — Peg to VWAP
a — Trailing Stop Peg
d — Peg to limit

Its usage is replaced by the field PegPriceType <1094> in the <PegInstructions> component block. The values are:

1 — Last peg
2 — mid-price peg
3 — opening peg
4 — market peg
5 — primary peg (primary market — buy at bid or sell at offer)
6 — Fixed peg to local best bid or offer at time of order
7 — Peg to VWAP
8 — Trailing Stop peg
9 — Peg to limit price

13. Deprecated OrderQty2 (192), SettlDate2 (193), Price2 (640), LastForwardPoints2 (641), BidForwardPoints2 (642), and OfferForwardPoints2 (643) [deprecated in FIX 5.0]

The following fields are being deprecated from use as FX support for FX Swaps will now use the New Order-Multileg <AB> and other existing multileg components: OrderQty2 <192>, SettlDate2 <193>, Price2 <640>, LastForwardPoints2 <641>, BidForwardPoints2 <642>, and OfferForwardPoints2 <643>

14. Deprecated QuoteType (537) from QuoteResponse message only [deprecated in FIX 5.0]

The QuoteType <537> is only deprecated from the QuoteResponse <AJ> message as it was a cut/paste error when the message was created in FIX 4.4 and does not make sense for this message.

15. Deprecated MDEntryOriginator (282), MDMkt (275) [deprecated in FIX 5.0]

The following fields are being deprecated from use: MDENtryOriginator <282> and MDMkt <275>. Its usage is replaced by corresponding values in PartyRole <452>.

16. Deprecated LocationID (283) and DeskID (284) from Market Data messages only [deprecated in FIX 5.0]

The following fields are being deprecated only from the Market Data messages: LocationID <283> and DeskID <284>. Its usage is replaced by corresponding values in PartyRole <452>.
