Parallel and equidistant lines are drawn two standard deviations above and below a Linear Regression trendline. The distance between the channel lines and the regression line is the greatest distance that any one closing price is from the regression line. Regression Channels contain price movement, the bottom channel line provides support and the top channel line provides resistance. Prices may extend outside of the channel for a short period of time but when prices remain outside the channel for a longer period of time, a reversal in trend may be indicated.

A Linear Regression trendline shows where equilibrium exists but Linear Regression Channels show the range prices can be expected to deviate from a trendline.
