A slow curve made by adding two rates of price change and smoothing them, used to spot where a rise begins at the end of a long fall.

Concept

One line is drawn in a lower panel. It adds “how many % the price has risen since 14 candles ago” and “since 11 candles ago”, then smooths the result with a 10-candle weighted average.

Because it moves slowly, it does not react to small wiggles. It was originally designed to find where the curve “climbs back from below 0” after a long fall.

80 candles with volume, and the Coppock Curve line in a lower panel. While the price falls and then moves sideways at the bottom, the curve slowly bottoms out below 0 and turns up. At candle 60 (↑) the curve moves above 0, and afterwards the price and the curve rise together. Keyboard: ←/→ to move, +/− to zoom, 0 to see the whole chart.

The curve crossed 0 well after the bottom — it is slow, but in return it is fooled less by small swings. This chart was picked because the price rose after the crossing; it does not always happen. Drag the chart sideways with a finger or the mouse to move it, and pinch with two fingers to zoom in. With a keyboard, click the chart, then use ←/→ to move and +/− to zoom.

How it is calculated

Take the % change of the close compared with 14 candles ago and with 11 candles ago, and add the two.

The 10-candle weighted moving average of that sum is the Coppock Curve. A weighted average gives recent candles more weight (the latest counts 10 times, the oldest once).

Trading ideas

Crossing 0: when the curve bottoms out below 0 after a long fall and then moves above 0, it is commonly read as “the start of a long rise”. The chart on this page shows that scene.

Turning up: some traders take the point where the curve stops falling and turns up, still below 0, as an earlier signal. It is wrong more often for the same reason.

Common traps

  • It is slow. By the time it crosses 0, the price has often already risen a fair way from the bottom.
  • In a sideways market it moves back and forth around 0 and the signal keeps flipping.
  • None of these are sure signals. Read them together with the trend (lesson 2).

In the game

  • “Coppock Curve” is a “Standard” weapon and uses 1 of the “Sub-charts” panels (limit 2). Volume in the starting setup already uses 1, so adding it brings it to 2 (0 left).
  • When the line goes below 0 somewhere on screen, a dotted zero line is drawn in the panel.
