Title: Re[2]: [amibroker] Re: UnKnown error msg: "Out of present range"
thank you... however I don't use PositionSize statements.
Also, and this is strange, the problem disappeared. I cannot replicate it anymore. The code worked fine for several weeks, then I had a few days that the error occurred (at random times/tickers), and now it is gone. The code and EOD data wasn't changed - I didn't even shut down my computer.
