Coppock Curve
COPPApplies a weighted moving average to the sum of two rate-of-change readings (default 14 and 11 months). Edwin Coppock designed it specifically to identify long-term bear market bottoms in stock indices.
Tips
The original Coppock signal is a zero-line cross from below after a trough; ignore crosses that start above zero
On shorter timeframes the curve still works but generates more noise; confirm with a trend filter like a 200-period MA
