Hello All,

Can someone let me know if Sequence Reset message should have 43=N or 43=Y?

Which message is correct of these 2?
What should be the response for both?

Whenever you are communicating to your counterparty that a message with the currenty sequence number may have already been sent you must set the possdup flag to “Y”.

According to the FIX spec

Upon receipt of a Resend Request, the resender can respond in one of three ways:

  1. retransmit the requested messages (in order) with the original sequence numbers and PossDupFlag set to “Y”
  2. issue a SeqReset-GapFill with PossDupFlag set to “Y” message to replace the retransmission of administrative and application messages
  3. issue a SeqReset-Reset with PossDupFlag set to “Y” to force sequence number synchronization

I hope this answers your question
