About

Coppock Curve momentum strategy: long when the Coppock Curve (WMA of two ROC sums) crosses above zero, exit on the cross below zero.

Default 14/11/10 reflects Edwin Coppock's original 1962 setting.
Combine with a higher-timeframe trend for confirmation.
Best on monthly/weekly charts for long-term swings.
