The Coppock curve
The Coppock curve is +7.83 and rising.
- The curve
- It is above zero and has been rising for 6 bars. The 14-bar and 11-bar rates of change add up to +9.41% on the last bar.
- How it is read
- Coppock built it for monthly closes of a stock index, with one signal: the curve turning up while still below zero, read as the end of a long decline. Many traders also watch the turn down from above zero and the zero cross.
- Read it with care
- It is slow by design and meant for long-term turns; on short bars it turns often and says less. It gives no timing for the next bar.

A curve for the long turns
Edwin Coppock published his curve in 1962 to spot the bottoms of long market declines. It adds the 14-month and 11-month rates of change and smooths the sum with a 10-month weighted average. He chose the lengths after asking how long people take to get over a loss, and looked for one thing: the curve turning up while below zero.
