GBM Prob: nearest unswept H/L (up to 50 bars)

This indicator is designed to analyze market structure and price behavior in relation to previous highs and lows. It automatically identifies prior swing highs and lows and tracks whether they have been taken by the current price movement.

The main goal of the indicator is to show which side of the market has already been cleared of liquidity and where untouched liquidity remains. Based on this data, it calculates the percentage of liquidity taken, helping traders assess the directional bias of price.

The indicator can be used as a higher timeframe filter (D1, H4) and as contextual guidance for entries on lower timeframes during the London and New York sessions. It works especially well with ICT / SMC concepts, OTE zones, and liquidity-based analysis.

Suitable for both intraday and swing trading, the indicator helps traders make more informed decisions and avoid trading against already swept liquidity.
