Since the new version ist out I am encountering a problem which I never had before. When I am doing long backtests (~4 hours and up) it occurs that the tester stops without any observable reason. If I try to click the pause-button it does not react, I also cannot cancel, only closing the application helps. This suddenly happened on all my strategies and on all four machines I am using. This behavior started whenever I replaced the old Forex version by the new one on one of the machines. All strategies are Java code (no mql4 bridge). I built markers into the code to ensure that the code does not stop due to a failuere in the code. The result was negative: The code is always executed until the end. For this reason and for the reason that it used to work fine before for all of my strategies, I exclude failures in the code. It seems that the next tick is not provided to the tester. The CPU load of the process drops to zero, thus there is no hanging loop. The failure occures independent from the date of the historical data and independent from the selected pairs (only eurusd was always selected), thus I excluded a corrupted data file. Are there any other things I could try to get rid of that failure?

Is there any exceptions in Java console? You can enable java console by going to Control panel-> Java -> advanced tab and selecting always show for java console option

Okay, I did this. The console says:

However, trying again to run the test passes the particular data point without any problem. Test period was 1.1.2009 until 1.1.2010.
