Custom ZIG ZAG with alligator

Hi,

so this is whats i need:

a custom ZIG ZAG, from lows to higs, taking into account a custom alligator.

Only the lows and highs will be VALID if a candle is completely on the other side of the alligator lines and doesnt even touch any alligator line.

Frome side to side, i will give further explanations to the programmer. Its not difficult.
