Communication between two strategies

[ct]

What is the easiest/most efficient way to share a value between two strategies on the SAME chart? Can I share a global value? I saw the post about using this on different charts but wasn't sure if it was true for the same chart as well.

I wasn't sure what was supported under the Ninja Trader implementation and thought I would ask before I beat my head against a rock.

Thanks/danke

Unfortunately this is beyond of what we support. However, you might see value in trying the concept of "static" in C#.

Guten morgan. Thanks for the fast reply.

ok, I will give it a try. I wasn't sure if "not supported" was "doesn't work" or is just unsupported. Sounds like it may be ok.

Here is what I received from my technical expert.

"There is no way to add global variable,
instead a very simple custom indicator with one property can be developed, which can be set and retrieved from any other indicator or strategy."

Does it look like this will work to you?

[NinjaTrader_Dierk]

Statement is incorrect: Since NinjaScript is C# you can add any global/static variable you like by custom coding.

But again: this is beyond of what we support. Please contact a NinjaScript consultant if you need further support on that matter. http://www.ninjatrader.com/webnew/pa...injaScript.htm

OK, thanks for the help.

it´s very easy ct! you create in region vars in [Estrategy1] a var with "public static ....." example:

#region Variables

public static bool MessengerInterStrategicVar = false ;

#endregion


Now, you call, write or change your var in [Strategy2].

Example:

(Put the name of class or strategy1 after var name)

Strategy1.MessengerInterStrategicVar = true ;

test with debug print!

Print (" Var from remote strategy status:" + Strategy1.MessengerInterStrategicVar.ToString());

woalaa! It can work! I think soo!
remember to load both strategys in your chart!

Kewl. I will give that a try. Many thanks!!!

It worked perfect. You are a sheer genius!

This apparently only works with strategies?

I tried the technique on two indicators...the "remote" indicator does not compile since it contains a reference to a variable that's defined in the "primary" indicator.

Any way around this? Do I need to define it as a "public static" variable in the "remote" indicator?

I have not tried this myself, but you could try defining it in UserDefinedMethods, which is a partial base class all of your indicators use.

Dierk -- if you're still following this discussion, is OnBarUpdate always called from the same thread or would this code need to be made threadsafe? I've wondered about that for my own uses. From watching the output it looks like the strategies are called one after the other.

[NinjaTrader_Dierk]

I did no follow this thread in detail but all strategy event methods are executed in the same thread.

PeteS,
I tried this out , and it seemed to work. Here is a code snippet:
partial class Indicator
{
double wrkVal = 0;
public double testMethod()
{
wrkVal = wrkVal + 1.0;
return wrkVal;
}
}


With this I can finally access wrkVar from other indicators.

Bormir, where did you place this?

In userdefinedmethods?

[Bormir]

zoltran,
I made a copy of UserDefinedMethods and named it TestUserMethods. I have attached the whole test file for you to look at. It is interesting. It looks like you can access wrkVar directly from any indicator
