Is your feature request related to a problem? Please describe. Per https://www.fixtrading.org/groups/continuousmkts/ Sequence number resets are a bore.

Describe the solution you'd like The implementation proposed is to use an unsigned 64 bit integer for a sequence number.

Using 1 billion sequence numbers per second, that will last for 584 years until they run out.

So we can leave the problem to our great, great, great (more) grandchildren to solve!
