ZigZag indicator is used to search highs and lows on a chart by showing support and resistance levels. This indicator is available on MT4 platform. It is, however, characterized by considerable repainting.
This is why we propose a version modified by Rita Lasker (Green Forex Group) without the repainting trait, but with a built-in e-mailed sound alarm and the signal that’s visualized with a big arrow. Still, it must be said that the arrow’s movements should be taken with a grain of salt.
15 minutes is the suggested time interval.
