Multiple Trading Sessions

Imported from previous forum

I am new to FIX and I’m non-technical.

I would like to know how FIX handles multiple trading sessions for the same trade date spanning a 24+ hour trading day.

For example, the regular trading session begins at 4PM on December 1 which really is the start of trade date December 2. Once that session ends at 2:30PM, a second session will begin at 4PM and end at 6PM - still trade date Dec. 2. NOTE: This could only occur on the last business day of the week.

Thanks for your anticipated help.
