Supply/Demand zones very specific way for Tradingview Indicator

The indicator needs to detect zones based on my discretionary trading process, not generic supply/demand logic. I trade futures, mainly NQ/MNQ and ES/MES, and I manually mark zones using multi-timeframe analysis. Core logic needed: • Detect supply and demand zones from 4H, 1H, and 30m candles • Start with 4H zones, then refine with 1H and 30m zones • Zones are based on two nearby candle bodies that are close to even / overlapping • Zone boundaries should include the full candle wicks, not just bodies • Only scan the current and previous trading session • Filter out low-quality continuation pauses and random two-candle patterns • Require meaningful displacement or break of structure after the base • Invalidate demand when price closes below the zone • Invalidate supply when price closes above the zone • Option to fade or delete invalidated zones • Label zones by timeframe, e.g. “4H Supply,” “1H Supply,” “30m Demand”
