Time Series Forecast (TSF) is the instrument of technical analysis including linear measurement of regression computed as per the method of least-squares. Time Series Forecast is similar to linear regression in the part of determining presence/absence of trend on a considered time-frame. On chart TSF is drawn as the curve consisting of the last points of several lines of linear regression trend.
Besides, Time Series Forecast defines incline angle for Forex trend (ascending or descending) and is able to forecast further movement of price on market. That is to say, under ascending trend, Time Series Forecast defines its incline angle and through matching it with real price calculates its value in the next period of time. If tendency of price movement remains, the indicator is able to define course of its movement at a rather high precision.
