MAPeriod	Moving average period
option	Select between two possible Coppock formulas

Description

Coppock Curve is a long-term price momentum indicator used primarily to recognize major bottoms in the stock market. The Coppock formula was introduced in 1962 by Edwin Sedgwick Coppock. A buy signal is formed when there is an upturn in the curve after an extreme low in the curve. A sell signal is formed when there is a higher peak in stock prices but a lower peak in the Coppock curve.

Calculation

Two calculation options of the Coppock Curve are possible:

Option 1:

WMA( ROC( Series,ROCPeriod1 ) + ROC( Series,ROCPeriod2 ), MAperiod );

Option 2, from a TASC article:

WMA((SMA( Series, 22 ) / SMA( Series 250 bars ago, 22 ) - 1), 150);
