I need an indicator in Mt5 or trading view The indicator detects Double Top / Double Bottom patterns. Pattern is only valid if it forms during a clear impulsive leg (up for DT, down for DB) and divergence (( RSI)) . If the pattern appears inside a corrective move, it is ignored. But if it appears in the next impulsive leg after correction, it is accepted. (Impulse vs corrective is filtered using ATR/ADX/slope rules or other methods can serve the indicator.

What the indicator does (very short brief) • Detects Double Top / Double Bottom patterns from price pivots. • Two stages for each pattern: 1. Forming (pre-break: shape & proximity valid) 2. Breakout (neckline broken with close-confirmation) • Filters (configurable): • Impulse filter: last leg to 2nd swing must be impulsive (ATR/ADX/slope rules). • RSI divergence: DT requires RSI(peak2) RSI(trough1). • Minimum structure size: enforces at least 5 candles across the two swings (via min bars between pivots). • Trade levels on breakout: computes Entry (neckline), SL (beyond extremes + ATR margin), TP1/TP2/TP3 (multiples of pattern height). • Chart output: optional neckline & levels, small labels with key info (entry, SL, TPs, filter status). • Alerts: four clean conditions • Forming_DT, Forming_DB, Breakout_DT, Breakout_DB (messages include symbol, timeframe; breakout alerts include entry/SL placeholders). • No repaint after pivot confirmation (pivots are taken pivotL bars later). • Timeframes: designed for 1m–4h. • Inputs (key): pivotL, lookbackBars, maxDiffPct, minBarsBetween, confirmBars, useRSI/rsiLen, useImpulseFilter (+ ATR/ADX/slope params), tpMult1/2/3, slAtrMargin, plotLines, showLabels.
