Dynamic High Low Band Overlay from a Rolling Price Range

Summary

The Dynamic High/Low Band Overlay places two bands on a price chart using the high and low range over a chosen period. Its inputs are the lookback period and an expansion factor. The upper band is positioned from the rolling minimum toward the maximum by the expansion fraction; the lower band is positioned from the rolling maximum back toward the minimum by the same fraction.

This is a compact description of a range-based overlay, not a complete trading method. The document does not specify recommended input values, clarify whether the expansion factor is constrained to a particular range, or explain how traders should act when price approaches or crosses either band. It provides no market examples, backtest results, or evidence that the levels forecast reversals or breakouts. The formulas describe band placement, while interpretation and validation remain open questions.

Key ideas

• The overlay uses the highest and lowest prices over a specified period.
• Its period and expansion factor are the two stated inputs.
• The expansion factor sets each band’s position within the rolling high-low range.
• The document defines the calculations but supplies no trading rules or evidence of performance.
