One zigzag settings are being used.

Basically, the EA draw trendline by zigzag and there will be two trendlines at a time, however trendlines are legging, and I can't seem to get it right for the trendlines to be on real-time event.

I would place the EA on a number of charts e.g on 18 charts, the EA would run for hours eventually the EA would be removed from 6 charts for no reason. I am struggling to resolve it.
