The ICT-SMC Setup Checklist is an indicator designed to verify ICT/SMC trading setups through a structured 3-step institutional order flow sequence. It confirms setups by tracking: (1) liquidity sweeps at fresh BSL/SSL swing levels with staleness detection, (2) order blocks combined with structure flips (CHoCH/BOS) validated by supporting order blocks and invalidated if counter-structure appears, and (3) Fair Value Gap (FVG) entries confirmed by price wicks and rejections outside the gap. The tool includes built-in filters such as ICT Kill Zones (London Open, NY Open, London Close, Asia Open) to flag setups outside high-probability trading windows, ATR-based ranging market detection to suppress signals during consolidation, ATR-scaled thresholds adapting to instrument volatility, and optional SMT divergence for cross-instrument confirmation. A live status label displays the setup’s current state—NO SETUP, BUILDING, LONG/SHORT SETUP confirmed, or warning states like RANGING or INVALIDATED—along with a detailed 3-step confirmation breakdown. This indicator is intended for ICT/SMC traders familiar with liquidity concepts, market structure, and FVGs who seek a disciplined, rules-based confirmation tool rather than an automatic signal generator. It supports analysis based on market structure and order flow concepts, using bar data as input.
