how to not allow a Strat to start if the instrument is being used by another strat

[gm7_forum]

Hi, I'm wondering if it's possible either with a feature in NinjaTrader or a way to code it in to stop a strat from kicking off if the instrument is being used on another strat.

For example if I have 3 strats all running NQ instrument and all 3 are enabled and 1 is currently in a live trade, another strat meets all the conditions and should kick off and start running but I want it to ignore the trade since another strat is live. Is this possible?

Hello gm7_forum,

Thanks for your post.

A NinjaScript strategy cannot see orders placed by other strategies. They also cannot see any orders that are manually placed.

There would be no NinjaScript methods or properties to prevent a NinjaScript strategy from being enabled if another strategy is running on the same instrument.

Something you could consider is using PositionAccount.MarketPosition to check if you are in a flat position on the account before submitting an order from the strategy to the same account the other strategy is running on.
