UMDF 2.0 - BM&FBOVESPA Segment
TCP Replayer and TCP Historical Replayer
The TCP Replayer functionality allows a client to request messages that were already sent through the incremental stream during the day. These messages will be returned to the client over a TCP connection (a FIX 4.4 session). The same connection is used for both the request and the retransmission.
This method of recovery should only be used if few messages were lost. For late joiners to the market, on in case of massive loss of messages, the snapshot recovery stream should be used.
Additionally, the TCP Historical Replayer is an alternative feed with higher response time that allows querying all incremental MD messages (up to the message with sequence number 1). It is recommended only for charting purpose.
