All About Center of Gravity Indicator (COG)

Center of Gravity Indicator

The Center of Gravity indicator or also known as COG is actually an oscillator with almost zero lag. John F Ehlers introduced this COG indicator in 2002. It is a modern oscillator. The COG indicator is an oscillator that is smoothed to prevent undesirable whipsaws. We can characterize the center of Gravity by the following essential features.

  1. The smoothing helps to clearly see price turning points.
  2. The indicator helps to see price reversals early.
  3. Fast and early actions can be taken due to the zero-lag effect.

Center of Gravity Indicator Formula

The Center of Gravity indicator formula is calculated from the total sum of prices over a period that has been defined by the user. The actual formula is provided below.

By default, the COG indicator is plotted on a 10-day period and calculated from the closing price of a candle. These parameters can be customized. Instead of the close price, you can select open, high, low, HL/2, HLC/3, HLCC/4, OHLC/4, etc.

On Upstox Pro

In the same way, you can attach the Center Of Gravity indicator in the Upstox Pro terminal. We can also use the same parameters here.

Trading Strategy using the Center of Gravity Indicator

#1. Simple Trading Strategy

  • Create a buy position when COG is at the bottom and exit buy or short sell when COG is coming down from the top.
  • As the Center of Gravity indicator is really smooth the turning points are easy to understand.

#2. Divergence Trading using the Center of Gravity Indicator

The COG can also spot the divergence very nicely. In fact, I have found that it is one of the best tools to spot divergence. A bullish divergence occurs when the price makes a lower low but the COG does not support the price. Rather it starts moving higher making a higher low. You can enter a long trade if you spot a bullish divergence. On the other hand, when the price makes higher highs, but the COG fails to make higher highs, it is a bearish divergence. You can enter a short trade.

Do not take the divergence alone to enter a trade. Further confirmations are needed from the price breaking trend lines or it crossing important moving averages.

#3. Combining COG with RSI

Open a chart and put these 2 indicators on the chart. The first one is a 10-period COG and the other is a 14-period Relative Strength Index. You need to plot the RSI with a special setting. Make the overbought and oversold levels different. Keep anything above 50 as overbought and keep anything below 50 as oversold. Plot the overbought and oversold levels in different colors.

Also, draw a horizontal line around the midpoint of the COG indicator. You can not calculate the exact midpoint as the COG overbought and oversold levels are not fully defined. So you can draw a line at approximately the midpoint.

The Setup

The trading rules

Open a buy order when the COG is above the midpoint and the RSI is above 50. Similarly, short sell when the COG comes below the midpoint and the RSI is also below 50. Watch the image below for the full setup.
