This indicator is an interpretation of the indicator Center of Gravity J. F. Ehlers. Center of Gravity actually has a zero lag and allows to define turning points precisely. This indicator is the result of Ehler's study of adaptive filters. The indicator Center of Gravity allows to identify main pivot points almost without any lag. The idea of calculating a center of gravity appeared from the investigation of lags of different filters with the finite impulse response in accordance with the relative amplitude of filter coefficients. SMA (Simple Moving Average) is a filter, in which all coefficients have one and the same value. As a result the center of gravity of SMA is an exact center of the filter.

The indicator is not redrawing. It generates a signal when a candle is fully formed.
