Adding multiple Bar Series in separate indicators and loading into Strategy

[Magzor]

Hey. Say I have an indicator A that is adding a volumetric bar series and indicator B which is loading daily chart, hourly, 15min. Now I use there two indicators in a strategy together. Will this mess up the bar series array in the strategy?

[QuantKey_Bruce]

No. But, the strategy has to load all of the data series needed by either nested indicator during the strategy's state.configure, and you should instantiate the indicators during state.dataloaded.

Hello Magzor,

Bruce is providing good information.

The strategy will also have to call the same AddDataSeries() calls as any hosted indicator that calls AddDataSeries().

Adding a data series does not change other data series.

Your logic can process on specific BarsInProgress.

Hi Bruce and Chelsea,
Thanks for the replies!
So as far as I understand from the replies; as long as the same type of bar data is loaded, then the order of the BarsArray does not have to match between the indicator and the strategy

[QuantKey_Bruce]

Correct, the order loaded does not have to match. They just have to all be there somewhere. If the inner (nested) indicator tries to access something that wasn't loaded in the outer (hosting) indicator, it will raise an exception and terminate.

Perfect, that makes what I want to design a lot more flexible. Thanks for the explanation!
