Time Series Forecast (TSF)
The Time Series Forecast (TSF) is a linear regression calculation that plots each bar’s current regression value using the least square fit method. This indicator is sometimes referred to as a moving linear regression similar to a moving average. For example, the TSF value that covers 10 days will have the same value as a 10-day Time Series Forecast. This differs slightly from the Linear Regression indicator in that the Linear Regression indicator does not add the slope to the ending value of the regression line.
The best fit line associated with the n points (x1, y1), (x2, y2), . . . , (xn, yn) has the form
y = mx + b
