Dear Members of the forum,
I have a weird problem with my ProScreener. All the default scans work fine (High Volatility High Volume, Bearish Engulfing, etc). As soon as I try to execute my own screener, I get an error message that is always the same.
To make sure the problem is not with my code, I used the sample screener code (screenshot 1), but as soon as I try to execute it, I get this error message (screenshot 2).
Any suggestions what I should do? I already tried to reinstall ProRealTime, but it also didn’t work.
