ATR SuperTrend with Noise-Responsive Band Expansion

Summary

This strategy modifies a conventional ATR-based SuperTrend by checking how close the closing price is to the previous trend line. When the distance falls below a configurable ATR threshold, it moves the line farther from price by an ATR-scaled amount and marks the band as dotted. Otherwise, the usual trailing-band update applies. A selectable price source feeds the upper and lower bands, and a change in trend state triggers a long or short entry.

The supplied script shows configurable ATR length, base multiplier, noise threshold, expansion amount, cash sizing, and commission assumptions. It does not provide strategy-report results or comparative tests demonstrating that the noise rule improves performance. The claim that this reduces false reversals should therefore be treated as a hypothesis. Results will depend on the asset, timeframe, source choice, and parameter settings, and the document gives no systematic validation across markets.

Key ideas

• The strategy computes SuperTrend bands from ATR and a user-selected price source.
• When price is within an ATR-scaled distance of the prior line, the line retreats by a configurable ATR amount.
• Trend reversals occur when the close crosses the updated band, triggering a position in the new direction.
• Dotted bands identify bars when the noise adjustment is active.
• The document provides no comparative performance evidence for the noise filter.
