Center Of Gravity
The Center Of Gravity (COG) is calculated from the sum of prices over a user defined period. A signal line which is an moving average of the COG is also plotted. Adjustable guides are shown to fine tune the signals. The user may change the input (close), method (EMA), period lengths and guide values. This indicator’s definition is further expressed in the condensed code given in the calculation below.
How To Trade Using Center Of Gravity
Adjust the top and bottom guides to control the quantity and quality of the trading signals. If the COG is above the top guide and crosses below the signal line a sell signal is generated. Conversely, if the COG is below the bottom guide and crosses above the signal line a buy signal will be given.
