Question on BarsPeriodType.Minute

[admiralpanda]

Hi,

I see in the documentation: https://ninjatrader.com/support/help...?builtfrom.htm
that when build from BarsPeriodType.Minute, the onDataPoint() is updated every minute. Does this mean it updates every whole minute, for ex. 3:30, 3:31 etc. Or does the minute start from when it is added to the chart?

Hello admiralpanda,

The BuiltFrom means the custom bar type will be loading historical minute data for calculations and not historical tick data.

The bar starts from the start of the whole minute based on the time stamps of the data.

So, this is just for Historical data or Real time data too?
Because even though I used BarsPeriodType.Minute, I still see the bars updating on each tick instead of updating after each minute.

Hello admiralpanda,

The BuiltFrom specifies how the historical data is loaded. In real-time OnDataPoint will be updating for every tick (to adjust the High, Low, Close prices as the bar builds).

Got it. Thank you!
