What is the Coppock Curve
The Coppock Curve is a long-term price momentum indicator meaning it is used to determine overbought and oversold areas although it is most commonly used to determine oversold areas. It is calculated as a 10-month weighted moving average of the sum of the 14-month rate of change and the 11-month rate of change for the index; it is also known as the “Coppock Guide.” The Coppock formula was introduced in Barron’s in 1962 by Edwin Sedgwick Coppock.
Learn how to trade with the Choppiness Index (Chop). One of the most important things to note about the choppiness index is that it is not a directional indicator. In other words the Choppiness Index will not show you the directional movement of any trend. The Choppiness index is supposed to calculate whether or not an option is in a trend or moving sideways. It does this by calculating a logistic function along with the average true range of an “n” period back with the default of 14. The Choppiness index can be used with a variety of other indicators to confirm a trend, or overbought and oversold levels on momentum indicators. Anything above the upper band is considered more choppy, while anything below the lower band is consider more in a trend movement. The maximum movement is that of an oscillator and is in between 0-100.
