Re: [Quickfixj-users] Daily sequence reset doubt

[Christoph J. <chr...@ma...>]

BTW, your counterparty also needs to reset at the correct time so I guess they would also like to 
know when you actually reset. Otherwise "funny" things can happen.
We had a counterparty which did not disconnect the session when their EndTime was reached but reset 
at the next intra-day disconnection. So most of the time everything worked but when there was a 
disconnection during the day (e.g. network problems) they started of at seqnum 1 mid-day which of 
course lead to problems since the sessions were constantly disconnecting due to too low seqnums...

Cheers,
Chris.
