Overview

Mc War OB + EMA visualizes bullish and bearish order block zones as customizable boxes, identifies confluence between order blocks and fair value gaps, and tracks mitigated blocks by recoloring broken zones. User settings control order block styling, label visibility, mitigation coloring, and box quantities.
