Center of Gravity (COG)

Center of Gravity (COG)

Center of Gravity (COG) indicator is based on adaptive filters concept developed by John F Ehlers. This trend indicator is well-smoothed and works practically with no lags. The smoothing allows to clearly identify the turning points, and the absence of lags provides the possibility to take the action early in the move.

Bars_back – total number of candles where the indicator will be shown.
M – linearity (1 – line, 2 – parabola … 9 - curve).

Can anyone explain the parameter settings of this indicator, to obtain the picture above? (Period, bars_back and m)

Hi, Xelix!
Thank you for your attention to the description of this indicator.
Bars_back – total number of the candles where indicator will be shown.
M – linearity (1 – line, 2 – parabola … 9 - curve).
Period – was unnecessary parameter (mainly the same as the Bars_back), so it has been deleted.
Best regards
