MARKET_STRUCTURE BOS_CHoCH is a trading indicator designed to automatically detect and plot key market structure elements—Break of Structure (BOS) and Change of Character (CHoCH)—across two independent timeframe layers on a single chart. It identifies swing highs and lows using configurable swing lengths, enabling clear visualization of bullish and bearish trends as well as early trend reversals. The indicator supports dual-layer structure detection, combining lower timeframe (LTF) micro-moves with higher timeframe (HTF) trend context, eliminating the need to switch between charts.

Users can select adaptive trading presets tailored for scalping, intraday, or swing trading styles, which automatically adjust swing lengths, visibility, and sensitivity. It also plots session key levels including daily, weekly, and monthly highs, lows, and opens, along with previous session levels (PDH, PDL, PWH, PWL, PMH, PML). The HTF structure can be sourced from actual higher timeframe bar data (e.g., H1, H4, D1) for true multi-timeframe analysis.

This indicator is suited for ICT/SMC traders, scalpers, swing traders, and prop firm traders who rely on BOS and CHoCH signals and session-based key levels, providing automated market structure visualization to reduce manual chart markup.
