ZigZag validity Expert

["SR" <raftsp@xxxxxxxxx>]

Since there are many users who showed interest in my indicator, I provide
here the code for a complete Expert. It uses Trends, Highlights, Symbols,
Alerts and a simple Commentary.

Zig(Close,10,% ): writeval(Zig(Close,10,% ),8.2)

writeif(Zig(Close,10,% )>ref(Zig(Close,10,% ),-1), "The ZigZag indicator is
ascending which means that prices are moving up.", "Prices move downward as
shown by the descending ZigZag indicator. ")
writeif(fml("ZigZag validity")=1, "This trend is confirmed by the ZigZag
validity indicator. Zig Zag has been valid for
writeval(barssince(cross(fml("ZigZag validity"),0.5)), 3.0) bars.",
"However, the trend is not confirmed yet. Zig Zag has been invalid for
writeval(barssince(cross(0.5,fml("ZigZag validity"))), 3.0) bars.")

___________________________________________

The above tools are very similar: Alerts coincide with Symbols and
Highlights coincide with Trends.
Therefore you may not need all of them at the same time.
Remember that, at any time, you can activate or deactivate any of the above
by clicking on the corresponding check box(es).

I hope this helps. In any case please drop me a note.
If there are any more problems also let me know.

Cheers
Spyros
