I am trying to run a back test from a swing GUI application. When I call the startStrategy function the call never returns and the strategy doesn't start. Running this strategy from a non GUI test application (TesterMain) the call to startStrategy returns and the strategy starts. Note: I am using 2.6.55.

Do you use the example strategy and GUI program or modified ones?

I use the supplied test programs but replace MA_PLay with my strategy.

Does the MA_Play work? How do you detect that your strategy "does not work" or "does not start"? For more efficient assistance, could you please provide a sample strategy which replicates the issue?

No MA_PLay does not work either. Calling ITesterClient.startStrategy just doesn't return from the call. There is nothing wrong with the strategy, as I can start it from the test program. When debugging, I step over the staretStrategy call but the next line is never reached and the onStart function in the strategy is never entered (I have break points on the line after the startStrategy and inside the onStart function of the strategy).

We successfully debugged the TesterMain program with MA_Play strategy.

I was calling the startStrategy from within a SwingWorker thread. Removing that code enabled it to work, but until it starts I cannot respond to any UI events. Is there a way of starting this from within a thread?

TesterMainGUIMode example within JForexStandaloneLibrary runs the strategy within its own thread.
