How to know when a bar closes when CalculateOnBarClose=false

[shodson]

If I have a strategy the has CalculateOnBarClose = false because I want to get OnBarUpdate() events for each tick, but I also want to make some decisions based on how a bar closes. So how can I determine when a bar closes when I have CalculateOnBarClose = false?

I'm using NT 6.5

Hello Shodson,

The opening of the next bar is the same event as the closing of the prior bar. You can use FirstTickOfBar to identify this. The reference sample below can help implementing this.

Thanks, I have a follow-up

If I am using multiple time frames, and my primary time frame is 15min and my secondary time frame is 1min then my OnBarUpdate() will be called 16 times: 15 times for BarsInProgress 1 and once for BarsInProgress 0, even if I have CalculateOnBarClose set to true, correct?

Hello Shodson,

I'm not sure the exact number of calls done. I suggest adding a counter if you would like to track this. When using CalculateOnBarClose == true, OnBarUpdate is called only once per bar. When set to false it will update for each incoming tick.

The reference sample below is good for understanding the sequence of OnBarUpdate() calls in a multi time frame strategy:

Excerpted below:
When working with multiple bar series objects it is important to understand the sequential order in which the OnBarUpdate() method is triggered. The bars will always run with the primary first followed by the secondary and so on.

Important: Primary bars will always execute before the secondary bar series.
If a bar is timestamped as 12:00PM on the 5min bar series, the call order between the equally timestamped 12:00PM bar on the 1min bar series is like this:
12:00PM 5min
12:00PM 1min
12:01PM 1min
12:02PM 1min
12:03PM 1min
12:04PM 1min
12:05PM 5min
12:05PM 1min
