running strategy on multiple instruments

[Tyler803]

I have a strategy i want to run on ES and NQ at the same time. Is there a way i can prevent the strategy from taking a position on 1 instrument if it is currently in a position on the other instrument. Eample: I don't want to enter a short position on ES if I am currently long NQ.

Hello Tyler803,

Yes you would need to use a multi instrument strategy so the strategy knows about both instruments and their position. There is a good deal of information in the following link going over using secondary series in a script. If you scroll all the way to the bottom there is a sample using two instruments for trading.

To know the position of each instrument you would use the plural Positions collection: https://ninjatrader.com/support/help...tsub=positions
