Pull the plug on the exchange'-).
It all depends on how you define your "day".
If no ticks occur between that tick and the Endsessiontime then it was the
last tick.
If you define the last trade of the day to include transactions on the close
the the trade time will be after the Endsessiontime. I've seen those as much
as 5 min later or more.

: Even that's not 100% reliable. Some days don't run until the normal
: closing time. But presumably you're more interested in the realtime
: behavior than in backtesting, so you'd know in realtime if the market
