Coppock curve

An obscure but simple technical oscillator developed by Edwin Coppock that utilizes historical stock data to indicate a positive change in the direction of stock prices. If the addition of the 14 month moving average of an index to an 11 month moving average of the same index produces a positive curve below a resulting 10 month weighted moving average it is an indication that a market bottom has occurred. Also called the Coppock Guide.
