Mastering the Center of Gravity Indicator for Precise Trading Signals

Understanding the Center of Gravity Indicator

The Center of Gravity (CoG) indicator is a powerful tool that can help you pinpoint turning points in the market with virtually no lag. Developed by J. F. Ehlers, this indicator stems from his research into adaptive filters, specifically focusing on how different filters respond over time.

What Makes the Center of Gravity Special?

One of the standout features of the CoG is its ability to identify key pivot points without the typical delays associated with many other indicators. The concept of calculating a center of gravity originated from examining the lags of various finite impulse response (FIR) filters, analyzing how their coefficients affect relative amplitude.

To break it down:

Simple Moving Average (SMA): This is a basic FIR filter where all coefficients hold the same value, making the center of gravity the exact midpoint of the filter.
Weighted Moving Average (WMA): Unlike the SMA, the WMA gives more weight to recent price changes, causing the center of gravity to shift slightly to the right, which ultimately reduces lag.

In essence, the CoG indicator allows you to maintain the integrity of original prices by ensuring that the sum of the products of coefficients and prices is divided by the sum of the coefficients.

How to Calculate the Center of Gravity

The CoG can be calculated using Ehlers' formula. Check out the visuals below for a clearer understanding:

Parameter Settings for Optimal Performance

When using the CoG indicator, you'll want to pay attention to a couple of key parameters:

Per=10: This defines the period for the indicator's calculations.
PriceType=0: This sets the type of price used in the calculations, giving you the main line (blue).

For the signal line (red), you have:

SmoothPer=3: This parameter sets the smoothing period for the main indicator line.
SmoothType=0: This denotes the smoothing type.
