Long Wick Detector isolates the candles that show genuine rejection: those whose wicks extend beyond a user-defined volatility threshold, the same anatomy that makes a pin bar worth watching. Each qualifying wick leaves a level on the chart, candle colors shift with wick size and level interactions, and levels stay visible for up to 1,000 bars.

Long wicks tend to mark strong market reactions (failed breakouts, supply and demand imbalances, aggressive rejections), which is why the levels they leave behind become natural reference points for future trades.

How to Trade the Long Wick Detector?

  • Unmitigated wick level: price has not returned since the rejection; if it revisits, watch for a potential reaction there.
  • Mitigated wick level: already tested by subsequent price action. The classification follows standard level-interaction rules, so you always know which zones remain untested.
  • Wick through a key level that reverses at once: a candidate liquidity grab or failed breakout, strongest with volume or order-block confluence behind it.
  • Threshold discipline: a low threshold surfaces even minor deviations, while a high one keeps only the most significant rejections.

Long Wick Detector Settings

  • Wick Threshold: defines what counts as a long wick relative to recent volatility. Lower it to capture more rejection events; raise it to filter down to the formations that matter for your style, from scalping through swing horizons.
