Unknown Runtime Error (Build 264)

[Andriy Moraru]

I am getting an unknown runtime error after the execution reaches some point inside OnCalculate() function. What could be the reason?

Please, see the attached mq5 file.

Thank you for message. Bug fixed. Please wait for updates.

Instead of an 'unknown error' should be 'Array out of range'

Check your code in line 155 ( dTmp += MathPow(price[position - i] - ExtMapBuffer5[position], 2); )

position-i can be negative
