[RS]ZigZag PA V1 — Indicateur par RicardoSantos

zigzag recognition harmonicpatterns zigzagindicator

ZigZag Based on price oscilation.
added pattern recognition, also added recognition of head and shoulders and contracting/expanding triangles to previous list of patterns :p

Use Alt Timeframe: enables optional timeframes, use higher timeframes to reduce noise.
Timeframe: said Alt Timeframe.
Show Patterns: toggles Pattern Recognition on.
