The Linear Regression Intercept tool calculates the line of best fit to the market price, using the least squares method, and is plotted on the chart in a way that is similar to a moving average. However, rather than being a simple averages calculation, the Linear Regression Intercept tool represents a statistically fitted line which reacts faster to changes in price when compared to a Moving Average.

To add the tool to your chart, select the tool from the Statistical tool group, and left-click on the chart or indicator on which you wish to add the tool. Optuma will then draw the tool using the default settings.

Scripting Function: LRINT()
