Plotting a Linear Regression Channel with Standard Deviation Bands

Summary

The document describes a chart indicator that draws a linear regression line over a configurable lookback period and adds bands one and two standard deviations above and below it. The regression slope is used to extend the fitted line back to the start of the period, while the standard deviation sets the distance of the surrounding bands. The indicator is intended to refresh on each new trading candle and display only on the latest bar.

This is a visualization tool rather than a complete trading strategy: the document gives no entry, exit, or position-sizing rules, and reports no backtest or performance evidence. It also does not explain how to interpret band touches, whether prices are expected to remain within the channel, or how the lookback period should be selected. The code is provided for a specific charting environment, so implementation details may need adaptation elsewhere.

Key ideas

• The indicator plots a linear regression line over a configurable lookback period.
• It draws upper and lower bands at one and two standard deviations from the regression line.
• The channel is intended to update as each new candle forms.
• The document provides no trading rules or evidence that the bands predict price moves.
• Lookback selection and interpretation of band crossings are left unspecified.
