Hey, I get a really annoying problem these days. After resetting my OS and installing Metrader 5, each time I want to run an EA in the Tester, I'm not able to change the input parameters. They are
automatically reseted to the default parameters in the Sourcecode. It makes me crazy...!! Looking forward to hear that Im not allone.
May work if you create a folder 'tester' in MQL5\Profiles. See here: https://www.mql5.com/en/forum/305970
