# R-Squared

This indicator belongs to the linear regression series. R-Squared is the correlation coefficient that specifies the quality of the linear regression line.

It is the calculation that gives R-Squared its name – the value is the square of the correlation coefficient, which in mathematics is prefixed with the Greek letter Rho (P).

The value of the oscillator fluctuates between 0 and 1. By default, the upper boundary line is located at 0.75, and the lower border is at 0.2. If the prices are in a sideways movement, the data is scattered around the regression line. R-Squared will have a value of 0 in the aforementioned situation. In a strong trend phase, the prices will remain within a tight range for an extended period of time; if these are located close to the regression line then the R-Squared indicator will have a value of 1. Stanley Kroll and Tushar Chande used the correlation coefficient as a trend filter in their book “
