Correlation between two instruments

[bernypaul]

Can you please tell me how to correlate two different instruments in custom strategy? I need to create an indicator of this above correlation in the strategy.

Hello Berny Paul,

Please see the link below for information about strategies that support multi instruments and time frames.

Thank you Jason.

I was going through the link which you provided. To confirm, The "APPL" and "MSFT" which described in that page are the instruments. right?

[NinjaTrader_Jason]

You are correct in your assumption.

These are the Apple and Microsoft stocks.

Thanks. But how can I make those dynamic. What I meant to say is - how can I use a parameter to define the instruments like we have parameters for indicators.

bernypaul, changing those added instruments dynamically in the Initialize() is unfortunately not supported.
