Certain features of the FIX Protocol which were implemented in earlier versions of the FIX Protocol specification, have been removed and replaced by a different approach. Such features have been labeled as "Removed" or "Replaced" throughout the FIX Specification document. The removed or replaced feature is no longer supported by this version of the FIX Protocol specification.

These features may or may not have been "Deprecated" in a previous version. Deprecation implies that implementations must support both approaches during the deprecation period. Removing and replacing a features without a deprecation period is based upon:

  • Supporting both approaches would result in a high degree of complexity and/or ambiguity.

The rationale behind removing 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 removed feature is identified below:

1. Replaced Field: ExecTransType (20) and values in ExecType and OrdStatus fields [Replaced in FIX 4.3]

The ExecTransType field introduced in FIX 2.7 has been removed and its values have been incorporated within the ExecType field. The ExecType field introduced in FIX 4.1 has had several values removed and a new value to represent the combination of the removed values. The ExecTransType and ExecType fields have effectively been merged into the ExecType field thus the removal of ExecTransType. Each field attempted to designate the type of Execution Report message received in a slightly different way. Both fields were designated as required. This became confusing and should be simplified by a single, merged field with the following mapping table:

Removed Value within ExecTransType (20) field Removed Value within OrdStatus <39> field Removed Value within ExecType <150> field ExecType <150>
0 New (various)
1 Cancel H Trade Cancel
2 Correct G Trade Correct
3 Status H Order Status
5 Replaced 5 Replace
1 Partial Fill F Trade
2 Fill

2. Replaced Fields: MaturityDay (205) and UnderlyingMaturityDay (314) [Replaced in FIX 4.3]

The MaturityDay (205) field introduced in FIX 4.1 has been removed and replaced by the MaturityDate <541> field. The MaturityMonthYear <200> field can still be used for standardized derivatives which are typically only referenced by month and year (e.g. S futures).

The UnderlyingMaturityDay (314) field introduced in FIX 4.2 has been removed and replaced by the UnderlyingMaturityDate <542> field. The UnderlyingMaturityMonthYear <313> can still be used for standardized derivatives which are typically only referenced by month and year (e.g. S futures).

3. Replaced Fields: ExecBroker (76), BrokerOfCredit (92), ClientID (109), ClearingFirm (439), ClearingAccount (440), and SettlLocation (166) [Replaced in FIX 4.3]

The ExecBroker (76), BrokerOfCredit (92), ClientID (109), ClearingFirm (439), ClearingAccount (440), and SettlLocation (166)> fields introduced prior to FIX 4.3 have been removed and the equivalent values can now be specified via PartyRole, PartyID, and PartyIDSource. In addition this Parties "component block" (see Volume 1: "Common Components of Application Messages") is flexible enough to allow new "roles" or types of firm identification to be specified without a corresponding increase in the number of FIX fields. All of the old field values can be specified via the following mapping table:

Removed Field PartyRole <452> (also see Volume 1: "Glossary") PartyID <448> PartyIDSource <447> PartySubID <523>
ExecBroker (76) 1 Executing Broker (value) (various)
BrokerOfCredit (92) 2 Broker Of Credit (value) (various)
ClientID (109) 3 Client ID (value) (various)
ClearingFirm (439) 4 Clearing Firm (value) (various)
ClearingAccount (440) 4 Clearing Firm (value)
SettlLocation (166) 10 Settlement Location CED = CEDEL
DTC = Depository Trust Company
EUR = Euroclear
FED = Federal Book Entry
PNY= Physical
PTC= Participant Trust Company
C Generally accepted market participant id
ISO Country Code (Local Market Settle Location) E ISO Country Code

4. Replaced Field Enumerations for Futures and Options for SecurityType <167> with CFICode <461> [Replaced in FIX 4.3]

The CFICode was introduced to improve granularity in specifying security type. The adoption of CFICode has made the values for futures and options in SecurityType <167> redundant.

The following Security Type values can be specified using CFICode via the following mapping table:

Value Removed From SecurityType <167> CFICode <461> value
"FUT" Future First position of CFICode = "F"
"OPT" Option First position of CFICode = "O"

5. Replaced Field: PutOrCall <201> and UnderlyingPutOrCall <315> with CFICode <461> [Replaced in FIX 4.3]

The CFICode was introduced to improve granularity in specifying security type. The adoption of CFICode has made the PutOrCall <201> redundant. The PutOrCall values are numeric and this has led to confusion on their usage as the data is not self describing. The CFICode uses a more readable format of"P" and"C" for put and call.

PutOrCall values can be specified using CFICode via the following mapping table:

Removed field PutOrCall <201> values CFICode <461> value
0 Put First position of CFICode = "O"
Second position of CFICode = "P"
1 Call First position of CFICode = "O"
Second position of CFICode = "C"

6. Replaced Field: CustomerOrFirm (204) with OrderCapacity <528> [Replaced in FIX 4.3]

The Rule80A (47>) and CustomerOrFirm (204) values have been merged and generalized into the new OrderCapacity <528> field. This was done to provide a more generalized approach to identifying order capacity across markets.

CustomerOrFim values can be specified using OrderCapacity via the following mapping table:

Removed Field CustomerOrFirm (204) values OrderCapacity <528> value
0 Customer A - Agency
1 Firm P - Principal

7. Replaced values: OptAttribute <206> with values in CFICode <461> [Replaced in FIX 4.3]

The CFICode <461> permits specification of the expiration style for options using more meaningful acronyms "A" for American and "E" for European. These values will replace the values currently used by some markets in the OptAttribute field. OptAttribute will still be used for versioning the option contract in the event of a corporate action, such as a split or merger, but will eliminate the problem when both the expiration style and a version number must be specified.

Certain OptAttribute values can be specified using CFICode via the following mapping table:

Values Removed From OptAttribute (OptAttribute <206>) CFICode <461>
L American First Position "O"
Second Position "C" or "P"
Third Position "A" for American Style Expiration
S European First Position "O"
Second Position "C" or "P"
Third Position "E" for European Style Expiration

8. Replaced values: AllocTransType <71> with values in AllocType <626> [Replaced in FIX 4.3]

The AllocTransType <71> field specified both the type of "transaction": new, cancel, replace and the type or purpose of the Allocation message. A new field AllocType was introduced in FIX 4.3 which specifies the type or purpose of the Allocation message. Three fields were removed from AllocTransType and are now part of AllocType. In addition, AllocType supports additional values which were not defined in AllocTransType.

Certain AllocTransType values can be specified using AllocType via the following mapping table:

Values Removed From AllocTransType <71> AllocType <626>
1 New (Note: "New" was dual-purpose:
1) a new transaction (this meaning remains)
2) buyside calculated allocation
The buyside calculated allocation meaning has been replaced by AllocType="Buyside Calculated")
1 Buyside Calculated (includes MiscFees and NetMoney)
3 Preliminary (without MiscFees and NetMoney) 2 Buyside Preliminary (without MiscFees and NetMoney)
4 Calculated (includes MiscFees and NetMoney) 3 Sellside Calculated Using Preliminary (includes MiscFees and NetMoney)
5 Calculated without Preliminary (sent unsolicited by broker, includes MiscFees and NetMoney) 4 Sellside Calculated Without Preliminary (sent unsolicited by sellside, includes MiscFees and NetMoney)

9. Replaced Field: RelatdSym (46) with Symbol <55> [Replaced in FIX 4.3]

The RelatdSym (46) field used in the News and Email messages prior to FIX 4.3 has been replaced by the Symbol <55> field thus allowing the News and Email messages to use the same Instrument component block as other FIX application messages.

10. Removed Deprecated Field: Benchmark (219) [Deprecated in FIX 4.3, Removed in FIX 4.4]

Affected Volume 3: field removed from Indication of Interest message.

The Benchmark field introduced in FIX 4.2 was deprecated in FIX 4.3 by the combined use of BenchmarkCurveCurrency, BenchmarkCurveName, and BenchmarkCurvePoint fields. (see Volume 1, SpreadOrBenchmarkCurveData component block). The Benchmark field was removed in FIX 4.4. Mapping of the replaced Benchmark field's values is as follows:

Replaced FieldBenchmark (219) Value BenchmarkCurveCurrency <220> BenchmarkCurveName <221> BenchmarkCurvePoint <222>
1 CURVE USD Treasury INTERPOLATED
2 5-YR USD Treasury 5Y
3 OLD-5 USD Treasury 5Y-OLD
4 10-YR USD Treasury 10Y
5 OLD-10 USD Treasury 10Y-OLD
6 30-YR USD Treasury 30Y
7 OLD-30 USD Treasury 30Y-OLD
8 3-MO-LIBOR USD LIBOR 3M
9 6-MO-LIBOR USD LIBOR 6M

11. Removed Deprecated "On Close"-related Values for OrdType Field [Deprecated in FIX 4.3, Removed in FIX 4.4]

Affected Volume 1: Glossary, Business Terms.
Affected Volume 6: values removed from OnClose field in Field Definitions.

Three "on close"-related values in the OrdType field were deprecated in FIX 4.3 by the combined use of a new TimeInForce "At the Close" value and OrdType values. These OrdType values were removed in FIX 4.4. This makes "On close" handling consistent with "On open" (as a TimeInForce vs. OrdType). Note that CMS (e.g. used by NYSE) uses a TimeInForce for On Open (OPG) and an OrdType for On Close. FIX 4.3 implemented a consistent handling of the two vs. a continuation of following CMS-based semantics. Mapping of the deprecated OrdType field's values is as follows:

Replaced Value within OrdType field TimeInForce <59> OrdType <40>
5 Market on close 7 "At the Close" 1 "Market"
A On close 7 "At the Close" 1 "Market"
B Limit on close 7 "At the Close" 2 "Limit"

12. Removed Deprecated Field: Rule80A (47>) [Deprecated and Replaced in FIX 4.3, Removed in FIX 4.4]

Affected Volume 4: field removed from New Order – Single, Order Cancel/Replace Request (aka Order Modification Request), and New Order List messages.

The Rule80A field (known prior to FIX 4.2 as "Rule80A" and in FIX 4.2 as "Rule80A (aka OrderCapacity)") was deprecated and replaced in FIX 4.3 by the combined use of the new to FIX 4.3 OrderCapacity and Order Restrictions fields. The Rule80A field was removed in FIX 4.4. The "(aka OrderCapacity)" designation has been removed from the Rule80A field. Mapping of the replaced Rule80A field's values is as follows:

Replaced Field
Rule80A (47) Value
OrderCapacity <528> OrderRestrictions <529>
Note datatype: MultipleValueString
Side <54>
A Agency single order A Agency
B Short exempt transaction (refer to A type) A Agency 6 or A Sell short exempt or Cross short exempt

13. Removed Deprecated Field: OnBehalfOfSendingTime (370) [Deprecated and Replaced in FIX 4.3, Removed in FIX 4.4]

Affected Volume 2: Message Routing Details – Third Party Message Routing, field removed from Standard Message Header.

The OnBehalfOfSendingTime field introduced in FIX 4.2 was deprecated and replaced in FIX 4.3 by the use of HopSendingTime <629> field which is part of the "Hops" repeating group. The OnBehalfOfSendingTime field was removed in FIX 4.4. See "Volume 2 - Standard Message Header" for HopSendingTime usage.

14. Removed three Deprecated "Forex - "-related Values for OrdType Field [Deprecated and Replaced in FIX 4.3, Removed in FIX 4.4]

Affected Volume 1: Glossary, Business Terms.
Affected Volume 6: values removed from OrdType field in Field Definitions.

Three "Forex - "-related values in the OrdType field were deprecated and replaced in FIX 4.3 by the combined use of a specifying Currency in the Product field and use of "regular" OrdType values. These OrdType values were removed in FIX 4.4. Mapping of the replaced OrdType field's values is as follows:

Replaced Value within OrdType field Product <460> OrdType <40>
C Forex - Market 4 "Currency" 1 "Market"
F Forex – Limit 4 "Currency" 2 "Limit"
H Forex – Previously Quoted 4 "Currency" D "Previously Quoted"

15. Replaced value: "A = T+1" with value with "2 = Next Day (T+1)" in SettlType <63> field [Replaced in FIX 4.4]

The value "A = T+1" was inadvertently added to the SettlType <63> field in FIX 4.3, however, the FIX specification already specified "2 = Next Day" which is synonymous. FIX 4.4 removed the "A=T+1" value and added " (T+1)" suffix to the "Next Day" value for clarification.

16. Replaced "Fixed Peg to Local best bid or offer at time of order" value from ExecInst <18> Field [Replaced in FIX 4.4]

See "Volume 4 - Order Handling Instructions - pegged orders". Mapping of the removed ExecInst field's value is as follows:

Replaced Value within ExecInst <18> field PegMoveType <835> PegScope <840> ExecInst <18>
T Fixed Peg to Local best bid or offer at time of 1 Fixed 1 Local R Primary peg

17. Removed unused field: RatioQty (319) [Replaced in FIX 4.4]

RatioQty (319) was no longer used by any FIX messages as of FIX version 4.3 designating it as "No longer used as of FIX 4.3". Note that FIX 4.3 replaced this field with LegRatioQty <623>.

18. Removed unused field: SecDefStatus (653) [Replaced in FIX 4.4]

SecDefStatus (653) was no longer used by any FIX messages as of FIX version 4.3 designating it as "No longer used as of FIX 4.3". Note that the FIX 4.3 draft process introduced this field, however, it was replaced with Security Definition messages prior to FIX 4.3 release.

19. Removed TotalVolumeTradedDate (449) and TotalVolumeTradedTime (450) fields [Replaced in FIX 4.4]

Removed TotalVolumeTradedDate (449) and TotalVolumeTradedTime (450) fields as FIX 4.4 specifies that MDEntryDate <272> and MDEntryTime <273> fields should be used instead.

20. Removed various Settlement Instructions-related fields [Replaced in FIX 4.4]

Removed the following Settlement Instructions-related fields:

  • SecuritySettlAgentName
  • SecuritySettlAgentCode
  • SecuritySettlAgentAcctNum
  • SecuritySettlAgentAcctName
  • SecuritySettlAgentContactName
  • SecuritySettlAgentContactPhone
  • CashSettlAgentName
  • CashSettlAgentCode
  • CashSettlAgentAcctNum
  • CashSettlAgentAcctName
  • CashSettlAgentContactName
  • CashSettlAgentContactPhone
replacing them with <SettlParties> (consistent with SI change made between ISO 7775 and ISO 15022). Removed SettlDepositoryCode (173), SettlBrkrCode (174), and SettlInstCode (175) fields. Refer to Appendix 6-H: Use of SettlInstGrp Component Block for further details.

21. Removed "Default", "Specific Allocation Account Overriding", and "Specific Allocation Account Standing" values from SettlInstMode <160> field [Replaced in FIX 4.4]

Refer to "Volume 5 – Settlement Instruction Fields Usage Matrix" for further details.

22. Removed several values from AllocType <626> field [Replaced in FIX 4.4]

Removed values: "Sellside Calculated Using Preliminary (includes MiscFees and NetMoney)", "Sellside Calculated Without Preliminary (sent unsolicited by sellside, includes MiscFees and NetMoney)", and "Buyside Ready-To-Book – Combined Set of Orders". Renamed value "Buyside Ready-To-Book – Single Order" to "Buyside Ready-To-Book" in FIX 4.4.

23. Removed several values from YieldType <235> field [Replaced in FIX 4.4]

Removing the following values from the YieldType field: "AVGLIFE = Yield To Average Life", "LONGEST = Yield to Longest Average (Sinking Fund Bonds)", and "SHORTEST = Yield to Shortest Average (Sinking Fund Bonds)" keeping "LONGAVGLIFE " and "SHORTAVGLIFE" values.

24. Removed AsgnReqID (831) from Data Dictionary [Removed in FIX 5.0 SP2]

Removed AsgnReqID (831) field from Data Dictionary. This field is not used anywhere and is obsolete.

25. Removed ExecRefID <19> from TrdCapRptSideGrp component [Removed in FIX 5.0 SP2]

The field ExecRefID <19> was removed from the TrdCapRptSideGrp component and replied by the use of a new field called SideExecID <1427>.
