Multi-Instrument indicator/strategy question

[ciro1963]

I created a custom indicator that calls a certain instrument for calculations- so I guess it's a multi-instrument or a 2 instrument indicator (BIP0 and BIP1). I want to create a multi-instrument strategy as well (BIP0 and BIP1) that calls this custom indicator for buy/sell action. Is this possible with Ninjatrader? I'm not sure how this would work or what the actual sequence would be. In the main strategy, for each BIP, I would like to call this custom indicator. So is it BIP0 (strategy) => BIP0 (indicator) => BIP1 (indicator) => BIP1 (strategy) => BIP0 (indicator) => BIP1 (indicator) => BIP0 (strategy) and so on?

Hello ciro1963,

Thank you for the question.

Yes, this is possible in NinjaTrader. A host (strategy) can call a script (indicator) which has other series as well.

To answer your question it would be best to see an example of specifically what happens with your current script's configuration. This would be a very good use case for Print statements to see specifically what the output is. https://ninjatrader.com/support/help...lightsub=print

What I would suggest doing to answer this question would be to create a new strategy and indicator which only have 1 print in OnBarUpdate:

Print("Strategy: " + BarsInProgress + " " + CurrentBar);

or for the indicator: 

Print("Indicator: " + BarsInProgress + " " + CurrentBar);

Then just call the indicator in the same way that you are now from the dummy strategy and run it on the same chart/config that you are asking about. Using these prints will specifically highlight the order of operations happening. You could see how the platform processes each script for each of the added series, 0 being the primary and 1 being the secondary BarsInprogress.

I look forward to being of further assistance.

I will try that. Thank you Jesse.
