Indicator executed on future bars

[mantak007]

Hi, when debugging single-timeframe indicator on historical data, it usually calls OnBarUpdate() only on visible bars. OnBarUpdate() for the bars behind the right side is executed after I scroll the chart to see them. One question is why this does not happen always...I have not found a consitency. Sometimes it waits, sometimes OnBarUpdate() is called for all the bars, even the hidden on the right. Second question, why it never waits in multi-timeframe indicator? I cannot check the output bar by bar, OnBarUpdate() is called for every bar, regardless if it's hidden or not. Is there a way how can I control this behavior and switch it off? Thank you.

Hello mantak007,
Single series indicators will process all bars up to the last visible bar on the chart until you scroll to the right to see more bars, then it will also process those as well.

Multiseries indicators however will process all bars all the way to the last bar loaded on the chart regardless of where you have the chart scrolled to.

This is expected and how the bars are referenced in NinjaTrader and there are no settings to overirde the behavior.
