Strategy overview

Linear Regression Bands borrow the familiar envelope idea — a centerline with bands plotted a set distance above and below it — but replace the moving-average center with a linear regression line fitted through the recent lookback window, so the middle of the channel is a best-fit trend rather than a lagging average. This entry decodes a video that uses that difference for a mean-reversion purpose: measuring how far price has stretched from a fitted trend before it snaps back, rather than trading the trend itself.

The source is Ali Casey's StatOasis video "Mean Reversion Strategy using Linear Regression Bands", and its structure is worth noting: it opens on linear regression as a trend-following tool, then turns that same construction into the backbone of a reversion setup. Along the way it places the bands side by side with Bollinger Bands and Keltner Channels — the natural reference points, since all three draw an envelope around a center but disagree on what the center is and what sets the width. The lookback matters here in a way it does not for a simple average: the video works through different lookback lengths to show how the fitted line, and therefore the band, changes character with the window it is measured over.

The second half introduces Percent B applied to the linear regression bands — the same normalizing idea used with Bollinger Bands, which collapses "where is price inside the channel" into a single number and turns a visual read into a threshold comparison. That is what makes the approach systematically testable, and the video closes on a parameter optimization pass over exactly those settings. No rule set was extracted from this video, so this page covers the concept and the source rather than a decoded rule breakdown.

Frequently asked questions

What are Linear Regression Bands?

Linear Regression Bands plot a channel around a linear regression line fitted to a set number of recent bars, with the upper and lower bands offset by a multiple of the deviation. The centerline is a best-fit trend through the lookback window rather than an average of it.

How do Linear Regression Bands differ from Bollinger Bands and Keltner Channels?

All three draw an envelope around a centerline, but they disagree on the ingredients: Bollinger Bands center on a moving average and size the bands from the standard deviation of price, Keltner Channels typically use an average true range for width, and Linear Regression Bands center on a fitted regression line. The source video compares them directly on the chart.

What is Percent B on Linear Regression Bands?

Percent B expresses where price sits inside the channel as a single normalized value — near the lower band, near the upper band, or somewhere between. Applying it to Linear Regression Bands lets a mean-reversion idea be stated as a numeric threshold instead of a visual judgment, which is what makes it optimizable and backtestable.

Does the lookback period change how Linear Regression Bands behave?

Yes. A regression line is fitted to a specific number of bars, so a short window tracks recent price closely while a longer window produces a flatter, slower reference. The video walks through more than one lookback length to illustrate that the choice of window is part of the setup, not a detail.
