SMC_CHOCH_BOS is a Smart Money Concepts indicator designed for the cTrader platform that automatically identifies key market structure elements on price charts. It detects Break of Structure (BOS) and Change of Character (CHoCH) by tracking confirmed swing highs and lows, where swings are validated by a configurable number of bars on each side. A bullish BOS or CHoCH occurs when price breaks above the last swing high; bearish signals occur when price breaks below the last swing low. The indicator distinguishes BOS and CHoCH based on the current trend state, identifying trend continuation or reversal accordingly.

Additionally, it marks Equal Highs (EQH) and Equal Lows (EQL) when consecutive swing points fall within a configurable pip tolerance, indicating potential liquidity pools. The indicator also automatically draws supply and demand zones around swing points that triggered structure breaks, with options to display only the most recent zones and extend them visually across the chart.

Key configurable parameters include swing length for pivot confirmation, equal high/low tolerance, maximum bars processed for performance, zone opacity and extension, and independent toggles for BOS, CHoCH, EQH/EQL, zones, and swing markers. The indicator provides visual signals to assist traders in analyzing market structure shifts and key levels.
