bar time vs. trade time?

[greentrader]

Is it true that the "Time" of a bar is always its Closing time, even as the bar is being formed when CalculateOnBarClose = false in realtime during an OnBarUpdate call?

If so, then is the OnMarketData callback the only way to get the time of a trade? (Other than looking at one's system clock during OnBarUpdate when CalculateOnBarClose = false.)

Thanks.

Correct on the timestamps. If you want to get time of a trade you can also check out the IExecution or even IOrder objects. They have a time property. http://www.ninjatrader-support.com/H...Execution.html

thanks Josh!

A related question: Since bars are stamped with their closing time, then is it true that watching for a bar "Time" change (in realtime) is equivalent to watching for FirstTickOfBar = true? (i.e., one stores the current bar Time in a Strategy variable, and then watches for a new Time to show up)

Yes, but I don't know why you would want to use timestamps to do that when you could use if (FirstTickOfBar).

Yes, but I don't know why you would want to use timestamps to do that when you could use if (FirstTickOfBar).

It turns out there is some common code I can write for both historical and realtime processing of bars if I compare bar times to determine if a new bar has been started. A small thing, but I just wanted to doublecheck that I wasn't missing something about FirstTickOfBar. Thanks.
