BarsInProgress - when/how to use?

[Calebg]

For my current strategy I am loading up to 3 different time frames using addDataSeries(), and I believe I understand what BarsInProgress does from a functional point of view, but try as I might I'm really missing the use-case(s)/context(s) in which BarsInProgress should/can be used, and why one would do so (I found the documentation at https://ninjatrader.com/support/help...nstruments.htm to be over-simplistic to the point that it wasn't helpful to me).

Another way to approach the same basic question(s) might be, what reasons are there for not just processing any/all multi-time frame logic without any specific BarsInProgress callouts? Would it be efficiency reasons? Synchronization issues? Something else, I'm overlooking?

Thank you

Hello Calebg,

BarsInProgress lets you know which series is processing in OnBarUpdate.

If you want to trigger an action when the primary bar is closing you can add a condition that BarsInProgress is 0.

If you want to place an order to a secondary instrument you can place the order using BarsInProgress 1.

Below is a public link to a reference sample that demonstrates adding a secondary series.
