Coppock curve

Type

Momentum oscillator

Short introduction

The Coppock curve, developed by Edwin Coppock, is based on Momentum and MA. It is used to identify long-term (multi-year) trends, and rather unsuitable for short-term trends.

Statement

The Coppock curve measures long-term trends by adding two long-term momentums. A weighted MA is formed on the basis of this sum. Because the base of the indicator is formed by momentum, the Coppock curve also oscillates around the zero line.

Formula/calculation

Coppock curve = WMAx(ROCy + ROCz)

where: WMA = Weighted Moving Average (weighted moving average)

Interpretation

The Coppock curve is interpreted in two different ways. In the standard interpretation, the turning of the line above the zero line downward is interpreted as a sell signal. The turning of the line below the zero line upward is interpreted as a buy signal.

Default setting

  • Weighted MA: 10 weeks
  • Short ROC: 11 weeks
  • Long ROC: 14 periods
