Hello,

I need some technical support. Today is November 12, 2025, and when I put the “ZONE HUNTER cBot” in the 15-minute timeframe, I get the same error message as melkerkhandmark. But when I test the bot in the 1-hour chart, it runs, but the error message appears at different intervals in the log, just like melkerkhandmark. This “Index was out of range.”

The more important problem I have is that I wanted to use the bot on another CTrader account, but I got an error message. Can you give me any advice? Or should I request a refund and then buy it again with the correct account?

Kind regards,
Edgar

Zone Hunter crashes live with:
03/11/2025 18:30:05.111 | Error | Crashed in OnBar with ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection

The bot still backtests fine and opens trades, but this crash repeats every bar when running live on AUDUSD M30. Even with full history loaded (about 6800 bars) and Trend Filter set to No, the bot throws this error on every bar close. The issue seems to be inside the OnBar() logic accessing an indicator buffer before it’s fully populated.

You might want to add a check like:
if (Bars.Count < minimumRequiredBars) return;
or
if (index < 0 || index >= myArray.Count) return;

Would be great to know if an update is planned — I’d be happy to help test it.
