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.
Trading on leveraged financial instruments may expose you to risk of loss greater than your deposits and is only suitable for experienced clients with the financial means to bear such risk. Trading on foreign exchange instruments (Forex) and contracts for difference (CFDs) is highly speculative and particularly complex and comes with a high level of risk due to leverage. You must ensure that you understand how these instruments work and that you can afford to take the high risk of losing your money. No information on this site is investment advice or a solicitation to buy or sell any financial instruments.
