Rolling Trendline

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: expanding bands mean rising volatility, tightening bands mean compression, and compression often precedes the next reset.

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.
