Discussion of article "Universal ZigZag" - page 4

 
MT5 2690 first two variants of zigzag without OOP:
  • iHighLowZigZag.mq5 - simple
  • ZigZag
  • on high/low.
  • iCloseZigZag.mq5 -
  • .

    work in the tester on history and when setting on real data, but they crash when debugging on real data, without error messages. Why is this so?

     
    make perfect sense
     
    Can you add a Sound Alert for when the ZigZag line reverses direction?  I do not understand when it happens, so I am always taken by surprise.
