I need to exchange some information (integer or array of doubles) between 2 independently running strategies (on the same JForex platform).
What is the best (recommended) approach?

Thanks a lot in advance.

Hi,
there is no such one the BEST approach. It depends form situation and given task.
We have samples which stores data in a data base and in the file.
Please consider these links:

JKubalek,

You'd need to have some means of 'discovering' the existence of a running instance of some other strategy. The JForex API makes a function available for doing this:

Map<Long,IStrategy>  IClient::getStartedStrategies()
    Returns map with ids mapped to associated strategies

You could, in theory, iterate over that map and check to see if the IStrategy instance you get is the instance you're currently executing code from or not. If it is an instance of the strategy class you want to communicate with, have an interface in place for submitting information to the target strategy instance.

I have a strong suspicion this will only work during live testing and will not work correctly during a back test. I'd consider finding a better way to pull this off that allows all running strategies to work independently.

I tried to use the code with Postgre instead of MySQL and took "Main.java" that comes with the JForex jars, to call the strategy "TestPosgreAcces.java".

It didn't work, returning an error when calling main method about log4j initialization.

Could you show me the way?

Thanks a lot.

Eduardo.
