Auto Trend Drawing
By LuxAlgoFeb 17, 2026
Auto Trend Drawing sketches trend structure the way a trader would by hand: it isolates the structurally important pivots in a recent window and joins them with a smooth spline, producing a flowing curve of the dominant direction. Where a classic trendline is a straight edge between two swings, this curve keeps adapting to fresh data: it recalculates retrospectively and is subject to repainting by design.
How to Trade the Auto Trend Drawing?
- Upward slope, price above: buyers own the structure; pullbacks toward the curve can behave as dynamic support.
- Downward slope, price below: sellers are in control; rallies into the curve often act as dynamic resistance.
- Flattening curve: compression and fading directional momentum, the environment that frequently precedes breakouts.
- Structural break: price decisively crossing and holding beyond the curve while its slope turns is the reversal tell.
Under the hood, prices are ATR-normalized so behavior stays consistent across instruments and timeframes, the Ramer-Douglas-Peucker pass strips insignificant points while preserving major swing highs and lows, and Catmull-Rom spline interpolation connects the surviving anchors. Given the retrospective recalculation, treat it as one of the library's trend tools for structure and bias rather than a real-time entry trigger.
Auto Trend Drawing Settings
- Window Size: how many recent bars are analyzed; larger captures macro structure, smaller hugs short-term behavior.
- Simplification Multiplier: filtering aggression. Higher for smoother macro shape, lower for a tighter, more reactive curve.
- ATR Length: period used for the volatility normalization.
- Curve Tension: how tightly the spline bends between anchors; 0.5 gives balanced centripetal curvature.
- Curve Resolution: calculated sub-points between anchors for a smoother line; color and width handle styling.
