Center of Gravity Oscillator
The Center of Gravity Oscillator is another useful Amibroker AFL that incorporates Amibroker data to measure price momentum and direction. It calculates the difference between the current price and the center of gravity to generate oscillating values. This oscillator assists traders in identifying overbought and oversold conditions in the market, helping them time their trades effectively.
