Strategies Communication

[corrado]

Hi,

I'm thinking of developing a strategy that communicates to other already running strategies in the Strategies tab and based on that makes trade decisions.
Can the running strategies in the Strategies tab get a reference (talk to) each other?
What is property StrategyBase.Strategies for? It seems to be empty always in my tests.

Thanks.

Hello,

Unfortunately you cannot have strategies talk to eachother in this manor. What you could do is create an indicator that returned the values that would be obtained from another strategy and then pass those to the strategy that needed them.

For our helpguide on passing values from an indicator to a strategy: http://www.ninjatrader.com/support/h...indicators.htm

Let me know if I can be of further assistance.

NinjaTrader_Lance,

Do you mean to develop an indicator that has a business logic of another strategy? Can you explain how an indicator can obtain values from another strategy?
I wanted to access a running live strategy to check its performance while it's running etc.

You would need to expose values from the strategy that can be read by the indicator. The indicator could then pass this information to another strategy.

We do not have an exact example to show you how to complete, however this sample on Exposing values that are not plots should help:

Got it! Thank you.

Corrado,

The simplest way for 2 strategies to communicate is by using static variable.

For example, define in UserDefinedMethods.cs:
partial class Strategy
{
protected static string myMessage ;
}

I would suggest creating a bit more sophisticated message structure though that would include sender, time sent, etc.

Make that a List<> of structs, each struct containing the details of the message, sender, time, etc.
