I have a strategy that compiles and runs well on one instrument.

Based on the simple parrallel example provided, I've written a second java file which will create multiple instances of the first strategy (to run multiple strategies within one strategy).

I don't know how to make a jar file of the first strategy so it can be included (via @Library) into the second strategy. I've used eclipse to create a jar file based on the 1st strategy's source code, but I get a warning that there are compile errors. Also, if I try to pull that jar file into a compile of the 2nd strategy, I get the following error: "myFirstStrategy cannot be resolved to a type"

I have 2 QUESTIONS:

When I compile the first strategy from the jforex platform, is a jar file created somewhere that I could move, or simply reference from the @Library statement within the second strategy?

Since I have to compile on the jforex platform, how do I create a jar file that will work with the 2nd parallel-execution strategy?

If you have difficulties to create a jar, maybe try creating a new java project, reference from it JForex API libraries, add a single strategy to it (the one you want to run multiple instances of), export it into a jar and see if it works out.
No, only a jfx file gets created.
See the answer above.

For your convenience we have attached the jar file used in the wiki example. So you might at first try if the example works for you on JForex client before making jars of your own. Also note that the compile error must have been caused by the lack of package notation at the beginning of StrategySimpleParallel class in JForex wiki (this now has been updated).

Thank you for your answer. Since I am new to java and eclipse, there could be several small things I'm doing wrong to prevent my jar from working properly. Please endure... I've attached 4 screen shots showing you step by step my method for creating the jar file and attempting to compile the multi-strategy class which pulls in the jar.

Also, the jar file you attached has an extension of .rar -- is that correct? Am I supposed to change it to .jar?

Thank you.

The .jar file creation looks ok, there must be some small nuance why this does not work out.
You have to extract the .rar file to a .jar file.

You can also consider other possibilities of running two instance of your strategy, for example:

a) from API:


        IStrategy strategy1 = new StrategySimple();
        IStrategy strategy2 = new StrategySimple();
        ((StrategySimple)strategy1).amount = 0.01;
        ((StrategySimple)strategy1).stopLossPips = 40;
        ((StrategySimple)strategy1).takeProfitPips = 40;
        ((StrategySimple)strategy2).amount = 0.02;
        ((StrategySimple)strategy2).stopLossPips = 60;
        ((StrategySimple)strategy2).takeProfitPips = 60;
        //strategy1.
        
        LOGGER.info("Starting strategy 1");
        client.startStrategy(strategy1);
        LOGGER.info("Starting strategy 2");
        client.startStrategy(strategy2);

b) Opening multiple instances of your strategy in JForex Client and manually pass them different parameters.
