What it does
The Linear Regression indicator fits a least-squares straight line through the closes of the last N bars and plots the endpoint (or the whole line/channel) as each bar completes. The fit minimizes the sum of squared distances between price and the line, giving the statistically best straight-line description of the recent trend. Channel versions add parallel lines at a set number of standard deviations around the regression line.

How traders use it
- Read the slope as trend: a rising regression line quantifies an uptrend, and slope flattening warns the trend is losing pace.
- Trade reversion to the line: price stretched far above or below the regression line tends to return to it, especially inside a channel.
- Use the channel edges (commonly 2 standard deviations) as entry zones with the line itself as the target.
- Compare slopes across timeframes: aligned regression slopes on higher and lower timeframes strengthen trend conviction.

Tips
- Right-click the indicator's line for quick actions — settings, visibility and removal without hunting through menus.
- Use Add to favorites in the legend menu; starred studies surface at the top of the picker.
- The legend eye toggles it off without losing your settings — handy for before/after comparisons.
Watch out for
- Each new bar refits the entire line, so historical values of the drawn line change as data arrives; the plotted history is not what you would have seen live bar by bar.
- A straight-line model fails around curved, accelerating or reversing price action.
