A Non-Repainting Supertrend Using Median Price and Lagged ATR

Summary

This Supertrend variation aims to keep its values stable after a bar closes. It replaces the moving average of the bars’ high-low midpoints with a moving statistical median, which the document describes as more robust to extreme values than an average. The indicator also calculates both its median reference and ATR using data from one bar earlier.

The lag is intended to avoid measuring a breakout partly against the current bar’s own range, an effect that can be more pronounced with a short ATR period. The document contrasts this with a version that uses current-bar inputs and mentions a displayed current price for quick checking. It gives a rationale for the design but no parameter settings, trading rules, charts, or comparative performance results. The claimed stability and robustness are therefore design intentions, not independently demonstrated outcomes in the material provided.

Key ideas

• The indicator uses a moving median of bar midpoint prices instead of a moving average.
• It references the median and ATR from the prior bar to reduce dependence on the current bar’s range.
• The lagged inputs are intended to make signals stable after bar close.
• The document offers a design rationale but no performance comparison or trading evaluation.
