Rolling Trendline
By LuxAlgoFeb 17, 2026
Rolling Trendline is an indicator on Vela, our next-generation charting platform, written in Pine Script®.
Rolling Trendline maintains the trendline you would otherwise keep redrawing: it projects a slope forward on every bar and re-anchors only when price deviates beyond a standard-deviation threshold. ATR-based zones wrap the projection, turning one line into volatility-aware support and resistance that never needs manual updates.
The slope is a linear regression slope measured across a configurable lookback; each new bar extends the line by it, so the bias persists instead of reshaping bar by bar. When price proves the path wrong, a small circle and a break mark the reset, and the line re-anchors at current price with fresh slope and zone width.
How to Trade the Rolling Trendline?
- Green projection: upward slope, long bias. Pullbacks into the line or the lower ATR zone are the classic continuation entries, with stops beyond the outer band.
- Red projection: downward slope. Rallies into the line or upper zone frame short setups the same way.
- Reset circle: a re-anchor flags a possible regime shift; when the new slope agrees with a structural breakout, treat it as confirmation rather than noise.
- Zone width: each reset sets the band width from the ATR at that moment, and it stays constant until the next reset, so a wider or narrower zone after a reset shows whether volatility was higher or lower when the line re-anchored.
Rolling Trendline Settings
- Slope Lookback: history feeding the regression; higher is smoother, lower is more reactive.
- Deviation Multiplier: reset sensitivity. Higher values tolerate wider swings before recalibrating.
- Slope Divisor: flattens the projected slope, useful on violently volatile assets.
- Source (default Close): price input for the calculation.
- ATR Length / ATR Multiplier: how volatility is measured and how wide the zones draw.
- Colors and line width: visual styling for phases, zones, and the line.
