I finished my first study and it works without errors.
However, when I want to run an optimization, I get an error, which says:
Message: Error in study
"name of the study" ::
Last two words are German an mean: Serious Error.
Also after I limited the number of parameters for optimization to a minimum I always get this error immediately after then optimization starts.
When I manualy choose those parameter settings, the signal runs without problems through the backtest, so I have no idea what could be the root-cause for this problem.
