Drawing a Price-Scaled Spiral from a Selected Swing High or Low

Summary

This chart indicator fits an Archimedean spiral to a historical price range, anchoring its center at a selected pivot high or pivot low. Users choose the pivot lookback length, which occurrence of a swing to reference, the anchor type, and the number of spiral turns. Horizontal and vertical flips alter the spiral’s orientation, while the plotted swing markers help show the selected anchor context.

The script scales the spiral’s vertical coordinates to the range of recent closing prices and draws it as connected line segments. It can color the segments uniformly or apply a gradient. The author presents the shape as a visual experiment and explicitly jokes about pattern-seeking; the document gives no market hypothesis, entry or exit rules, or evidence that the spiral forecasts prices. It is therefore best understood as a visualization rather than a validated technical signal, and its appearance will vary with the selected swing and chart history.

Key ideas

• The spiral is anchored to a configurable historical pivot high or pivot low.
• Lookback length, selected swing occurrence, number of turns, and orientation can be adjusted.
• The spiral’s vertical range is scaled using observed closing-price variation.
• The document presents no predictive rationale or trading-performance evidence for the shape.
