FIX Global Technical Committee

Preface

The Financial Information eXchange (FIX®) Protocol effort was initiated in 1992 by a group of institutions and brokers interested in streamlining their trading processes. These firms felt that they, and the industry as a whole, could benefit from efficiencies derived through the electronic communication of indications, orders and executions. The result is FIX, an open message standard controlled by no single entity, that can be structured to match the business requirements of each firm. The benefits are:

From the business flow perspective, FIX provides institutions, brokers, and other market participants a means of reducing the clutter of unnecessary telephone calls and scraps of paper, and facilitates targeting high quality information to specific individuals.
For technologists, FIX provides an open standard that leverages the development effort so that they can efficiently create links with a wide range of counterparties.
For vendors, FIX provides ready access to the industry, with the incumbent reduction in marketing effort and increase in potential client base.

Openness has been the key to FIX’s success. For that reason, while encouraging vendors to participate with the standard, FIX has remained vendor neutral. Similarly, FIX avoids over-standardization. It does not demand a single type of carrier (e.g., it will work with leased lines, frame relay, Internet, etc.), nor a single security protocol. It leaves many of these decisions to the individual firms that are using it. We do expect that, over time, the rules of engagement in these non-standardized areas will converge as technologies mature.

FIX is now used by a variety of firms and vendors. It has clearly emerged as the inter-firm messaging protocol of choice. FIX has grown from its original buy-side to sell-side equity trading roots. It is now used by markets (exchanges, “ECNs”, etc) and other market participants. In addition to equities, FIX currently supports four other products: Collective Investment Vehicles (CIVs), Derivatives, Fixed Income, and Foreign Exchange. The process for modifications to the specification is very open with input and feedback encouraged from the community. Those interested in providing input to the protocol are encouraged use the FIX website Discussion section or contact the FIX Global Technical Committee (GTC) Chairpersons). The FIX website is the main source of information, discussion, and notification of FIX-related events.

We look forward to your participation.

About FIX Protocol Limited

FIX Protocol Limited (FPL) oversees and manages the development of the FIX Protocol specification and encourages its use throughout the industry. FPL is open to due paying members representing business and technology professionals interested in guiding the growth and adoption of the FIX Protocol that work for: Buy-Side Firms, Sell-Side Firms, Exchanges, ECNs/ATSs, Utilities, Vendors, and Other Associations. For more information about membership please visit https://staging.fixtrading.org.

FIX Trading Community™ is a brand of FIX Protocol Ltd, a non-profit UK registered entity, originally created to own, maintain and develop the FIX Protocol messaging language.

FIX® is embedded into the fabric of the financial trading community, used by thousands of firms every day to complete millions of transactions in a cost-efficient and effective manner.

FIX has been created and continues to be developed through collaborative industry efforts with the intention that it remains as a non-proprietary, free and open protocol. Maintaining this position is of utmost importance, as the cost to the industry of a fee based alternative would prove incredibly expensive.

To ensure this status is protected, FIX Protocol Ltd is managed under a special “Purpose Trust” which owns the assets and enables the organisation to concentrate on promoting protocol adoption without undue risk or exposure. An effort that is further supported by legal protection afforded through the fees paid by member firms.

FIX Protocol Limited is represented by the following high-level organization:

Global Steering Committee comprised of the FPL Global Committee Chairs
Global Technical Committee comprised of Product/Region Committee Representatives
Global Product Committees (Fixed Income & Currencies, Listed Products & Exchanges)
Global Buy-Side Committee
Global Member Services Committee
Regional Committees (Americas, Asia Pacific, EMEA, Japan)

Introduction

The Financial Information Exchange (FIX®) Protocol is a message standard developed to facilitate the electronic exchange of information related to securities transactions. It is intended for use between trading partners wishing to automate communications.

The message protocol, as defined, will support a variety of business functions. FIX was originally defined for use in supporting US domestic equity trading with message traffic flowing directly between principals. As the protocol evolved, a number of fields were added to support cross-border trading, derivatives, fixed income, and other products. Similarly, the protocol was expanded to allow third parties to participate in the delivery of messages between trading partners. As subsequent versions of FIX are released, it is expected that functionality will continue to expand.

The FIX Family of Standards addresses the different needs of the application, encoding and session level. Whilst there is basically a single standard called FIX Latest for the application level defining business related data content, FIX offers a number of choices for the encoding of messages as well as for the session level, i.e. the technical interaction between counterparties to deliver data. There is a second standard for the application level called FIXatdl which is an XML based standard to specify the user interface components for algorithmic trading.

Specifications for the encoding (a.k.a. “syntax”) and the session level are called Technical Standards and have their own name and version together with their own documentation. FIX also supports industry standards such as Google Protocol Buffers (GPB) for encoding and Advanced Message Queuing Protocol (AMQP) for the session protocol. This document is only about FIX Latest, i.e. the application level.

The following table shows a comprehensive list of the FIX Family of Standards followed by a diagram of the FIX Technical Standard Stack:

FIX Protocol and Technical Standards
Standard	Acronym	Layer	Description

FIX-over-TLS	FIXS	Session	Standard to secure FIX sessions using the industry standard Transport Layer Security (TLS) protocol.

Organization of specification

The FIX Latest Specification is organized into multiple areas (a.k.a. “sections”), with each area covering specific categories followed by an appendix with detailed component and message layouts. The titles for areas other than the introduction are directly linked to the appropriate websites as part of the FIX Online Specification.

Message and Component Definitions

All areas contain definitions of FIX components and application messages. Components are sets of related data fields grouped together and are referenced by the component name in messages that they are used in. FIX components are organized as follows:

Global Components – are components commonly used by many messages defined across all areas of the FIX specification. These are the most commonly used components. Their definitions are found here.
Common Components – are section-specific components, i.e. these are components commonly used only by the FIX messages found in that area or section (e.g. pre-trade, trade, post-trade sections). Their definitions are found at the end of the appendix of the area-specific documentation.
Specific Components – are message category specific components, i.e. these are components that are used only by the FIX messages in a specific message category in a given area (e.g. Securities Reference Data message category). Their definitions are found in the appendix of the area-specific documentation in their respective message category.
Messages are described as part of the category description. Additionally, the detailed message layouts are found in the appendix of the area-specific documentation in their respective message category.
Messages are comprised of required, optional and conditionally required (fields which are required based on the presence or value of other fields) fields. Systems should be designed to operate when only the required and conditionally required fields are present.
Messages and components may have nested fields and components as part of repeating groups. The tag number (name) of a nested field (component) is prefixed with an arrow “→”.

Extension Pack Management

Extension Packs are the building blocks of FIX Latest and represent specific functional proposals that have been presented to and approved by the GTC. Extension Packs are applied to the repository in a cumulative manner, i.e. the latest Extension Pack always includes all previous Extension Packs. Extension Packs management will be conducted as follows:

Extension Packs will be assigned a unique, sequential number at the point they are approved by the GTC.
Extension Packs are applied to the most recent version of the repository and may be inclusive of prior Extension Packs.
At the point an Extension Pack has been applied, the updated repository, schema, and message tables will be publicly available.
When implementing a specific Extension Pack, ApplExtID(1156) may be used to specify the Extension Pack identifier, i.e. its number.
Users of an Extension Pack do not need to implement it in its entirety and do not need to implement other Extension Packs present in the repository. Rules of engagement need to be bilaterally agreed on to define the supported subset of FIX Latest.

List of Extension Packs

The following list contains all extension packs published after the release of FIX Version 5.0 Service Pack 2. The “size” information is intended to give an orientation as to the impact of an EP. This is primarily driven by the amount of new messages, fields and values but may also be due to business relevance.

FIX Protocol datatypes

FIX supports a number of different ASCII and binary encodings. This section only describes the definitions and value spaces of datatypes. They are shared among all FIX message encodings. The value space of a datatype is defined using the vocabulary of ISO/IEC 11404:2007 Information technology – General-Purpose Datatypes (GPD). The mapping of datatypes to a wire format, i.e. their lexical space (a.k.a. “syntax”), depends on the chosen encoding and is defined in the encoding’s respective Technical Standard specification. See the Introduction for a list of FIX encodings.

Note that some of the binary encodings (e.g. SBE) allow the usage of a more efficient value space as long as its values are a subset of the given datatype. For example, String fields may be limited to whole numbers in case of entity identifiers by using an int datatype instead. An int field, however, must never be changed to a String field as this would allow additional values not covered by the value space of the datatype int.

UTC and leap seconds

Note that UTC includes corrections for leap seconds, which are inserted to account for slowing of the rotation of the earth. Leap second insertion is declared by the International Earth Rotation Service (IERS) and has, since 1972, only occurred on the night of December 31 or June 30. The IERS considers March 31 and September 30 as secondary dates for leap second insertion but has never utilized these dates. During a leap second insertion, a UTCTimestamp field in tagvalue encoding may read “19981231-23:59:59”, “19981231-23:59:60”, “19990101-00:00:00” (see https://maia.usno.navy.mil/information/what-is-a-leap-second).

Global Components

Introduction

Global components are components that are used in two or more business areas, e.g. pre-trade and trade. With the objective of re-using components rather than creating new ones, existing components may become global due to a new FIX Extension Pack. This section not only shows the global components but also those that are currently common only within a single business area and conceptually identical to a global component.

The following sections are grouped by entities, e.g. instruments, parties, etc. The descriptions for the components are provided by component names’ alphabetical order within their group. In addition to the descriptive text, a given component is visualized with a diagram whenever it has one or more nested components. Only the first level of nesting is shown and “…” indicates more deeply nested components. The descriptions of the nested components of the first (or previous) level then contain a diagram with the next level of components nested within it.

Global Components for Securities

Some of the global components for an instrument (Instrument), its legs (InstrumentLeg), and its underlying instrument (UnderlyingInstrument) are conceptually identical. The descriptions for these conceptually identical global components are only provided once at the instrument level unless it is a component that is only present at the leg or underlying instrument level. The following table lists such global components whereby the links for all components go to the description of the instrument level component. Additional links at the end of the description go to the component layout.

Events

EvntGrp

This component is a repeating group that is part of the Instrument component and used to specify straightforward events associated with the instrument. Examples include put and call dates for bonds and options; first exercise date for options; inventory and delivery dates for commodities; start, end and roll dates for swaps. Use the ComplexEvents component for more advanced dates and events such as option, futures, commodities and equity swap observation and pricing events.

The EvntGrp component contains three different methods to express a “time” associated with the event using the EventDate(866) and EventTime(1145) pair of fields or the EventTimeUnit(1827) and EventTimePeriod(1826) pair of fields or EventMonthYear(2340). When this component is used one of these three time expression methods must be specified.

The EventDate(866), and optional EventTime(1145), may be used to specify an exact date and optional time for the event. The EventTimeUnit(1827) and EventTimePeriod(1826) may be used to express a time period associated with the event, e.g. 3-month, 4-years, 2-weeks. The EventMonthYear(2340), and optional EventTime(1145), may be used to express the event as a month of year, with optional day of month or week of month.

The component layouts are available here: EvntGrp, LegEvntGrp, UnderlyingEvntGrp.

Instrument

This component is used as part of many messages as well as repeating groups and contains all the fields commonly used to describe a security or instrument. Typically, the data elements in this component block are considered the static data of a security, data that may be commonly found in a security master database. The Instrument component may be used to describe any asset type supported by FIX. The component layout is available here.

Instrument Extensions

InstrumentExtension

This component identifies additional security attributes that are more commonly found for fixed income securities. The component layout is available here.

This component is a repeating group that is part of the InstrumentExtension component and may be used to carry the different dates (and timestamps) related to the reference data entry.

Instrument Identifier

RelatedInstrumentGrp

This component is a repeating group that is at the same hierarchical level as the Instrument component, describing relationships and linkages between the security, leg security and underlying security entries. If all instances of the UnderlyingInstrument component in the message are true underliers of the Instrument component, then the RelatedInstrumentGrp component is not needed. If any instance of the UnderlyingInstrument component has a different relationship, e.g. underlier of an instance of the InstrumentLeg component, stream, equity equivalent or nearest exchange-traded contract or if there are multiple instances of the InstrumentLeg component, then an entry for every relationship should be included in this component. When the RelatedInstrumentGrp component appears within a repeating group, each entry only applies to the Instrument component at the same hierarchical level.

In messages such as Email(35=C) and News(35=B), where the Instrument and the InstrumentLeg component are within their repeating groups, the RelatedInstrumentGrp component may be used to link legs and underliers to their appropriate base security.

For simple relationships such as identifying a “hedges for” security, the entry simply defines the symbol or identifier of an externally known security. For relationships within strategies and swaps, the entry refers up through one of the “related to” fields to the security, leg security, underlying security, stream or dividend period with which the related security has correlation. It then points down through RelatedSecurityID(1650) or RelatedSymbol(1649) to an UnderlyingInstrument instance in the current message defining the related security. The nature of the relationship is given in RelatedInstrumentType(1648).

StreamPaySide(40052) and StreamReceiveSide(40053) may be used to link the appropriate swap parties to their role in the stream. In pre-trade messages the side value (e.g. Side(54) field) of the request or order should be set to the same side value indicating the aggressor’s desired role. On fills and post-trade messages the executing firm takes the opposite side and indicates its role by setting StreamPaySide(40052) and StreamReceiveSide(40053) to the opposite side of the aggressor’s role.

Parties Identification

Parties

This component is a repeating group used to identify and convey information on the entities both central and peripheral to the financial transaction represented by the FIX message containing the Parties component. The Parties component allows many different types of entities to be expressed through use of the PartyRole(452) field and identifies the source scheme of the PartyID(448) through the PartyIDSource(447).

There are a number of conceptually identical components with different names due to the uniqueness constraints of the tagvalue encoding. NestedParties4 is one of those components. It is not a global component but a local component in the single/general order handling category of the trade area.

The component layouts are available here: Parties, NestedParties, NestedParties2, NestedParties3, RootParties3.

PtysSubGrp

This component is a repeating group that is part of the repeating group Parties. It is used to provide additional or supplemental information related to the instance of the identified party it is attached to.

There are a number of conceptually identical components with different names due to the uniqueness constraints of the tagvalue encoding. NstdPtys4SubGrp is one of those components. It is not a global component but a local component in the single/general order handling category of the trade area.

The component layouts are available here: PtysSubGrp, NstdPtysSubGrp, NstdPtys2SubGrp, NstdPtys3SubGrp, RootSubParties.

TargetParties

It provides information about one or more party(-ies) within the context of where this component appears in. It may be used to represent a list of parties subject to the action of the message this component appears in. The component layout is available here.

TargetPtysSubGrp

This component is a repeating group that is part of the repeating group TargetParties and conceptually identical to the PtysSubGrp. It is used to provide additional or supplemental information related to the instance of the identified party it is attached to. The component layout is available here.

PartyRelationshipGrp

This component is a repeating group that is part of the repeating group RelatedPartyDetailGrp. It is used to convey different types of relationships between two parties. Relationships between parties can be inferred or explicitly specified.

Party relationships can either be inferred based on PartyDetailRole(1693) or made explicit. For example, if PartyDetailRole(1693) = 1 (Executing Firm) and RelatedPartyDetailRole(1565) = 24 (Customer Account), it can be inferred that the executing firm trades for the customer account. This relationship can also be made explicit by using the PartyRelationshipGrp component and specifying PartyRelationship(1515) = 3 (Trades for).

Relationships between parties are modeled as a web or mesh. PartyRelationship(1515) = 0 (Is also) indicates that an entity of a specific party role is also an entity of different party role, e.g. an Executing Firm with one ID is also a Clearing Firm with another ID. With the exception of “Is also,” PartyRelationship(1515) is specified as a list of reciprocal relationships. This enables a relationship to be conveyed regardless of which party is specified in PartyDetailID(1691) and which is specified in RelatedPartyDetailID(1563).

The component layout is available here.

RelatedPartyDetailGrp

Note that when this component is marked as “required” in a message, either one of these three fields must be used to identify the order amount: OrderQty(38), CashOrderQty(152) or OrderPercent(516) (in the case of CIV). The component layout is available here.

RelatedOrderGrp

This component is a repeating group that may be used to identify orders that are related to the order identified outside of this component for a business purpose. For example, the bundling of multiple orders into a single order.

These timestamps are used to identify the timeframes for when an order or trade is received on the floor, received and executed by the broker, etc. The component layout is available here.

Global Components for Commissions and Fees

CommissionData

This component is used to carry commission information such as the type of commission and the rate. Use the CommissionDataGrp component as an alternative if multiple commissions or enhanced attributes are needed.

This component may be used to provide aggregated commission data of a given CommType(13) whereas the repeating group CommissionDataGrp may be used to include the detail splits provided the commission is of the same commission basis type. For example, CommissionData may contain CommType(13) of 3 (Absolute) and a Commission(12) value of “15”. CommissionDataGrp may be used to show how this Commission(12) value of “15” is split up as long as the CommissionBasis(2642) is also 3 (Absolute) for each of the instances added together. This method of aggregated commission data may also be applied to this component to provide a total when the instances of the detail splits in CommissionDataGrp component contain leg level information (indicated by the use of CommissionLegRefID(2649) in CommissionDataGrp component). It is only possible to aggregate values for a single commission basis type.

The component layout is available here.

CommissionDataGrp

This component is a repeating group that is used to carry commission information such as the type of commission and the rate. It provides an alternative to the CommissionData component if multiple commissions or enhanced attributes are needed.

This component is not intended for non-leg instances of the CommissionDataGrp component to represent aggregated values of the leg instances within the component when both leg and non-leg instances are included.

AllocCommissionDataGrp is a conceptually identical component. It is not a global component but a common component of the post-trade area.

The component layout is available here.

MiscFeesGrp

This component is a repeating group that is used to provide details of trade and transaction fees other than commissions, e.g. regulatory, exchange, taxes, levies, markup, trade reporting, etc.

MiscFeesGrp should be used to convey fees related to the transaction (e.g. taxes, transaction based fees, etc.) and should not be used to specify payments based on the price or terms of the contract (e.g. upfront fee, premium amount, security lending fee, contract-based rebates, related fee resets, payment frequency, etc.). For contractual payments use the PaymentGrp component instead.

The component layout is available here.

MiscFeesSubGrp

This component is a repeating group that is part of the MiscFeesGrp and used to provide further details for the instance of MiscFeeType(139) and MiscFeeAmt(137) it is attached to. The component layout is available here.

LegStipulations and UnderlyingStipulations are conceptually identical global components.

The component layout is available here.

Global Components for Header and Trailer

The global components StandardHeader and StandardTrailer are only partially relevant for the application layer. They are mainly linked to the FIX session layer and the tagvalue encoding of messages. A subset of the fields in the StandardHeader component and the CheckSum(10) field in the StandardTrailer component are required for the parsing of tagvalue encoded messages. Other encodings such as FIXML or Simple Binary Encoding (SBE) may use fields in the StandardHeader component, for example to convey the application layer version and extension in use.

HopGrp

This component is a repeating group that is part of the StandardHeader component and used to capture one or more third parties a message passes through to reach its final destination. It is applicable when messages are communicated/re-distributed via third parties that function as service bureaus or “hubs”. The component layout is available here.

StandardHeader

This component is the standard FIX message header required for tagvalue encoding and optional for other encodings. It is not intended to contain business level information. The component layout is available here.

This component is a repeating group that provides the ability to attach other media type documents to a FIX message for transmission. The media type can be any of the media types (previously referred to as MIME types) that are listed by IANA (www.iana.org) [RFC2046]. It is intended to be used to attach documents in other formats, such as PDF, TIFF, and Microsoft Word, for example, to a FIX message.

When this component is used within a business message, such as the TradeCaptureReport(35=AE) message, the attachment should supplement the data already contained in the business message. It is not intended to replace the content of the business message. The standard (required) fields within the business message shall be populated, even if they duplicate data expressed within the attachment(s). The component layout is available here.

YieldData

This component conveys yield information for a given fixed income security. The component layout is available here.

User defined fields

In order to provide maximum flexibility for its users, the FIX Protocol accommodates User Defined Fields (UDFs). These fields are intended to be implemented between consenting trading partners and should be used with caution to avoid conflicts, which will arise as multiple parties begin implementation of the protocol. It is suggested that if trading partners find that particular UDFs would add value to the wider community, they should be submitted as a Gap Analysis (see here for a template and process guideline) to the FIX Global Technical Committee to be standardized in an Extension Pack.

The tag numbers 5000 to 9999 have been reserved for UDFs, which are used as part of inter-firm communication. These tags can be registered/reserved via the FIX website. At this time, the available tag numbers in the user defined range of 5000 to 9999 have all been allocated. In December 2009 the FIX GTC Governance Board approved the use of tag numbers in the 20000 to 39999 range for use as user defined tags to be used bilaterally between parties. These tags do not need to be registered.

The GTC’s policy with regards to UDFs is for the community, where possible, to use tags, components or repeating groups from the latest Extension Pack in their legacy FIX implementation when these meet the requirements, as opposed to customised extensions through user defined fields, components, or repeating groups.

UDFs in the range 8000-8499 are reserved for the FIX Global Technical Committee for the support of regulatory requirements in supported legacy versions of FIX. UDFs in the range 8500-8999 are currently reserved for work-in-progress in China.

The tag numbers greater than or equal to 10000 and less than 20000 have been reserved for internal use (within a single firm) and do not need to be registered/reserved via the FIX website. The tag numbers in the 40000 to 49999 range are reserved for the FIX Global Technical Committee and have been used for standard fields related to the definition of OTC derivative instruments. The tag numbers of 50000 and above are reserved by the FIX Global Technical Committee and should not be used in FIX implementations.

Appendix: Global Components

Many of the FIX application messages are composed of common “building blocks” or sets of data fields. For instance, almost every FIX application message has the set of symbology-related fields used to define the “Instrument”: Symbol(55), SymbolSfx(65), SecurityIDSource(22), SecurityID(48) … ExchangeLookAlike(2603). Rather than replicate a common group of fields, the FIX specification specifies components which are simply referenced by component name within each application message which uses them. Thus when reviewing a specific message definition, the appropriate group of fields should be expanded and used whenever a component is identified.

Note that some components may be part of repeating groups thus if the component is denoted as part of a repeating group, then the entire group of fields representing the component are to be specified at the component’s repeating group “level” in the message definition and follow repeating group rules, e.g. concerning field order in case of tagvalue syntax.

The components identified within this section are referred to as “Global Components”. They are “Common Components” that are used across the two or more of the main business areas (pre-trade, trade, post-trade, infrastructure) and not just across the categories of a single business area.
