Message Notes

The News (B) message is used by a TT FIX to indicate that a FIX client login and order book download have completed and that the FIX client can begin sending order routing or order-releated messages.

FIX Market Data sessions now receive the News (B) message with Tag 58 equal to "Recovery is Complete". TT strongly recommends you configure your FIX Market Data client to wait until receiving this message before submitting any requests.
