Coppock Curve (CC)

The Coppock Curve indicator tries to identify buy signals in a market by looking at market activity on a monthly time scale. It adds the rates of change for a short and a long period of months and then smooths by another period's weighted moving average. Typically, a potential buy signal occurs when the indicator is below 0 and then rises above it.

Configuration Options

  • Field: Price or combination of prices to use as the base for average calculations. Possible values include:
    • Open
    • High
    • Low
    • Close
    • Adjusted Close
    • HL/2 \( \left ( \frac{High + Low}{2} \right ) \)
    • HLC/3 \( \left ( \frac{High + Low + Close}{3} \right ) \)
    • HLCC/4 \( \left ( \frac{High + Low + Close + Close}{4} \right ) \)
    • OHLC/4 \( \left ( \frac{Open + High + Low + Close}{4} \right ) \)
  • Short RoC: Number of periods in the short rate-of-change indicator.
  • Long RoC: Number of periods in the long rate-of-change indicator.
  • Period: Number of bars to use in the calculations.
  • Color Selectors: Colors to use for graph elements.
  • Display Axis Label: Whether to display the most recent value on the Y axis.


\[Coppock = WMA_\text{period}\;of\;(ROC_\text{Long RoC periods}+ROC_\text{Short RoC periods})\]


  • WMA is the weighted moving average.
  • ROC is the rate of change indicator.
