Big problem: array out of range (3297,29)

[Dieter]

Hallo Admin,

• no red errors when compiling
• no error message during the optimization
  But during trading, the EA is removed from the chart and the following error messages appear.

Is the failture known and can you tell me why this is going on?

Hello,

do you have any idea what is going on?

[eklonsousa]

@dieter No solution yet?

[eklonsousa]

@fxDreema any idea?

[fxpim]

In which timeframe are you testing the EA and which timeframe does the once-per-bar block use in which the error occurs? I've dealt with this error multiple times.
