Re: [Quickfixj-users] Reset Sequnces Design

[Liubov E. <liu...@gm...>]

Hi,

Thank you for your explanation.

One more question: imagine the situation of engine restart during the trade
day. Will the necessity of sequences reset be checked during the engine
start? In other words, does the engine care on the start if there is a
first connection inside the defined trade day or not?

Example:

* StartTime=03:00:00 EndTime=06:00:00*

*1) Engine starts for the first time at 04:00:00*
*2) Engine restarts at 05:00:00*

What will be the sequence behavior in these two cases?
