You can use any value in this tag to identify the TT session for the FIX client. TT FIX will return this value in tag 49 (SenderCompID) in its responses.

50 SenderSubID N String

For order routing messages, this tag overrides the exchange Operator ID configured in Setup.

57 TargetSubID C String

The value maps to the Alias field configured for a user in Setup.

Condition: Required when multiple users are associated with the account.

The value matches the Tag 1 (Account) in the corresponding request.

Note: Account names are stored as case-sensitive strings. Users must match case-sensitivity when using Tag 1 (Account).

762 SecuritySubType N String

Sub-type qualification or identification of the SecurityType

For example, an instrument with SecurityType(167)="MLEG" might use this tag to specify the name of the option or futures strategy, such as "Calendar", "Vertical", or "Butterfly".

For sythetic staged orders, i.e., HandlInst (21)=3 and SecurityType(167)="Sythentic", the TT FIX engine checks whether the instrument already exists and automatically creates the synthetic spread if the instrument does not exist.

Note: This tag can be included in messages sent from TT FIX Drop Copy sessions when the Compliance Feed (Send original order/cancel/change messages and pending execution reports) setting is enabled in Setup.

Tag # Field Name Req’d Data type Comments
10 Checksum Y String

Unencrypted three-character checksum

This tag must always be the last field in a message (i.e. it serves, with the trailing <SOH>, as the end-of-message delimiter).

Message Notes

The Security Definition Request (c) message is used by FIX clients to request contract data.

You can filter your security definitions so that TT FIX supplies only those instruments that match the specified values for one or more of the following tags:

  • Tag 55 (Symbol)
  • Tag 100 (ExDestination)
  • Tag 167 (SecurityType)
  • Tag 207 (SecurityExchange)
  • Tag 48 (SecurityID)

    If Tag 48 (SecurityID) is provided, you must also provide Tag 207 (SecurityExchange).

Sending a Security Definition Request (c) message instructs TT FIX to subscribe for contracts that match the filter criteria. TT FIX sends Security Definition (d) messages for all matching contracts and sends new Security Definition (d) messages if any of the contract details, such as tick size, change. Additionally, if a market adds a new contract that matches the filter criteria, TT FIX automatically sends a Security Definition (d) message for the new contract.

TT FIX uses AND logic to build the query, so specifying multiple tags reduces the matched securities. If you send none of the tags in the request, TT FIXreturns all securities for all visible markets.

Note: If TT FIX finds no contracts that match the specified filter, it sends no response back to the FIX client
