Inter-Strategy Communication

[Master.Aurora]

Hello Support,

I am creating a strategy in which i need to do a little bit of inter-strategy communication. Here is the scenario:

I will have multiple instances of the same strategy running simultaneously on same and/or different instruments with same and/or different parameter settings. I need to achieve a stop & reverse feature whereby if the program is Long with Strategy 1 and before the position is closed, Strategy 2 signals a Short trade, we would like for the program to Close the LONG position and Initiate the SHORT one.

Now what i dont understand is how to make the communicate between Strategy 1 & Strategy 2 so that i can code this feature. For reference, i am using the unmanaged approach for orders in my strategy,

Please advise.

Thanks
Umer

Hello Umer,

Thank you for your note.


Unfortunately, NinjaScripts do not have any inter-communication ability.

However, I agree that this would be a good feature to include. I am going to submit this feature request to our Development department.
Thank you for your suggestion for the improvement of NinjaTrader. Your feedback will be considered for a future release of NinjaTrader.


Something that may help you toward your goal would be checking the overall account position. See the link below to a thread that discusses how to accomplish that.

Please let me know if I can be of any other assistance.

So why not just code both strategies into one class, and do the StopAndReverse right in there?

I guess you missed it in my original post so i will explain again. There is one strategy that i need to run on different instruments & with different parameters

Of course. So the strategy that is causing the reversal may have different parameters. Oops. Forgive my denseness, please.

Thank You ChelseaB.

In the meanwhile, we created an out of the box solutions for this problem. I wrote a blog post about it. Here is the link to it:

Please feel free to spread this to other people looking to find a solution to their problems (like me) so that they have something to work with until NT has the feature built into it

Thanks Again.

Heed the warning about using static variables. Especially if there is no lock in place to handle attempts by multiple threads to update the same values, while other threads are reading those values.

koganam,

Thank you for the tip. I will be very careful as I put this together.

As always, you are a big help. Keep up the good work.

Yeah i understand the pitfalls involved in this approach. But if you read my article, i only scribbled down an algorithm. In my implementation, i did actually take many precautionary measures

Anyways, thanks for pointing it out. I will add it to the article as well
