Source Code

The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.

Overview

SMC Killzone State Engine (Bidirectional) detects higher timeframe Fair Value Gaps (FVG) and Order Blocks (OB), tracking state transitions from active session to POI identification and mitigation based on custom percentage thresholds. Main settings adjust killzone hours, trade direction, higher timeframe resolution, and visual options. It uses higher timeframe data with lookahead enabled, creating historical lookahead bias.
