Coppock Curve
Coppock Curve is an investment tool used in technical analysis for predicting bear market lows
IN forex and Currency trading There are two commonly accepted ways of determining buy and sell signals from a Coppock Curve - The first is to trade on reversals from extremes.
When the indicator was published in Barron’s (1962), it was intended to generate buy signals in the S&P 500 only, and the suggested signal was an upturn in the Coppock Curve from an extreme low.

The second interpretation involves divergence analysis.
The initial thrust off of a low in the stock market is often accompanied by the highest Coppock Curve reading (peak momentum). Subsequent advances tend to be accompanied by diminishing momentum (lower peaks on the Coppock Curve). That combination of a higher peak in price accompanied by a lower peak in the Coppock Curve creates a bearish divergence. Those signals warn of a weakening, aging advance, but often precede the ultimate top.
Currency markets
Currencies tend to fall in the middle, since they’re symmetrical markets. Buyers and sellers are the same groups, they just have different nationalities. Consequently, reversals tend to be sharp, but the parabolic blow-offs of commodities and waterfall declines of stocks are not typical of currency markets. The Coppock Curve can be an excellent indicator for currencies, signaling both buys and sells. Because currency markets don't often reach the one-sided, emotional extremes of stock and commodity markets, reversals in currency markets signaled by the Coppock Curve may not be as enduring as those in other markets.
Coppock Curve - this is a tool that helps trades know when the market has hit the bottom. Analyzed on a monthly basis, this curve is calculated over a year and two month period and a ten month period and then working out a moving average between them. When the curve is negative, traders should buy, whereas when the curve is positive that is a sign to sell. Originally based on psychological criterion, the curve is in "mourning" when the market is down. In the Episcopalian church people traditionally mourn for a period of between eleven and fourteen months, hence the application to the Coppock Curve.
