Kalman Supertrend (High vs Low) Bands
Inspired by BackQuant, this script modifies the original Kalman Hull Supertrend by replacing the close price with High and Low sources. This creates clearer trend definition and better trend tracking.
This is one of the best trend indicators that can be used for trend trading or to capture reversals with high clarity.
Key Features:
Kalman High/Low Bands — Smooths market noise while separating bullish and bearish zones.
BB & SS Alerts — Triggered only when the entire candle closes outside both bands, helping filter out false breakouts.
Supertrend (optional) — Can be toggled on/off to monitor potential short-term or early trend shifts.
Customizable Display — Show/hide bands, fills, and live candle coloring for chart clarity.
Reversal Insight:
For 4H and Daily charts, reversal signals appear to be quite accurate when the price retests the trend bands before continuing the move.
How to Use:
BB appears when a candle fully closes above both High/Low Kalman bands — possible bullish breakout.
SS appears when a candle fully closes below both bands — possible bearish breakdown.
Supertrend toggle can confirm shorter-term moves or early reversals.
