Data Transfer between Strategies

[Baruch]

Ralph thanks,
If I understand you correctly, if I want all my strategies with different names to share data btw them, I can lieve the "Member search pattern" empty or put in "a" for all strategies?

Hello Baruch,

Sorry, that was a mistake from my side. What I ment was the following: Your strategies could share a single member list (the list) or even access separated member lists (a list).

An empty search pattern detects nothing (or perhaps strategies without a name, I am not sure). If you would like to share a single member list among all strategies, I would apply a * as regular expression, this pattern should accept anything.

Hello Ralph,
Thanks a lot for helping me.
I still have problems.
1. I can not make 2 strategy instances to be together in a list.
2. When I did make them together, only the last instance gave correct results.

I attach a test strategy.
I put it on 2 charts with different instruments and 1 min time frame.

Can you see whats wrong please.

Regards,
Baruch

Hello Baruch,

I gave you an incorrect recommendation regarding a "universal" regular expression, because * is an illegal regex. The correct one to catch every possible strategy name is: .*

I re-installed the test implementation from this thread (DataTransfer2) on my computer and instantiated 2 strategies on a single chart:
I named the first one Test1 and applied the member search pattern .*
I named the second one Test2 and applied the member search pattern .*

Look at the log result attached below. It behaves like expected. The first strategy is instantated first and starts its member group including Test1 (itself). Then the second strategy is instantiated and is added to the member group of the first strategy. And at least the second strategy creates its own member group containing both strategies.

If you would be able to replicate that on your side, that should be a good starting point for your own implementation.

Thank you for all explorations.
I am thinking about sharing Strategy data for all Indicators within.
like a shot in dark,have you any suggestion for me,it is so hard!

Hello maorachow,


there are no such restrictions. The class implementations use their own namespace and are independent from the Indicator- and Strategy namespace. You can put the code somewhere, you always need to refer to that namespace in your application.


The example at the beginning of this thread transfers data between strategies. But a transfer between strategies and indicators follows the same rules, there is no difference.

Thank you Ralph,
Glad to hear Class solution.
I am delving into the transfer2.cs code.
Let's discuss the question later.
