FIX2.7

The sequence reset message is used to reestablish the incoming sequence number on the opposing side. In the event of an application failure it may be necessary to resync sequence numbers on the sending and receiving sides.

The sending application will initiate the sequence reset. The message is used to reset the value of the last sequence number sent (which on the receiving side will reset the value of the next expected sequence number).

It is assumed that the purpose of the sequence reset message is to recover from an out-of-sequence condition, therefore, the MsgSeqNum in the header should be ignored (i.e. the receipt of a sequence reset message with an out of sequence MsgSeqNum should not generate resend requests).

The sequence reset can only increase the sequence number; if a sequence reset is received attempting to decrease the next expected sequence number the message should be rejected.
