Message Notes

The Market Data Request (V) message is used by a FIX client to request market data information from TT FIX. You can request information like the top of book (Bid, Ask, and session prices) and market depth data.

TT FIX responds to a Market Data Request (V) message with a Market Data Snapshot Full Refresh (W) message. Additionally:

  • If the FIX Client sets Tag 263 (SubscriptionRequestType) to 0, TT FIX sends no further messages. It does not update the market data.

  • If the FIX Client sets Tag 263 (SubscriptionRequestType) to 1, TT FIX updates market data according to the setting the FIX Client uses in Tag 265 (MDUpdateType):

  • If the FIX Client sets Tag 263 (SubscriptionRequestType) to 2, TT FIX stops sending updates.

If TT FIX cannot fulfill a request for market data because the request contains an invalid instrument, it sends a Market Data Request Reject (Y) message.

Note: If you submit this request for an exchange whose Price Server is down, TT FIX also responds with a Market Data Request Reject (Y) message.

Some exchanges disseminate implied prices as well as direct (Bid/Ask) prices. Trying to merge these two separate price streams can result in crossed markets for a brief moment. TT FIX forwards all market data updates from exchanges, so FIX clients can encounter this scenario as well. FIX clients that subscribe for direct and implied prices should be written to account for this possibility.
