Coppock Curve is often overlooked, but it is one of the most important tools in technical analysis, especially when it comes to forex trading.  It was originally designed to spot buying opportunities in stock markets.

Copper Curve has since been adopted by forex traders as a reliable indicator for long-term market trends.

Coppock curve in Forex analysis

The Coppock Curve in Forex analysis is a momentum indicator that helps traders spot long-term market trends and potential turning points.

It was developed in 1962 by economist Edwin Coppock, initially for use in stock market analysis.

However, forex traders have found it useful in identifying potential buy signals during market downturns or identifying prolonged uptrends.

The curve is calculated based on the weighted moving average (WMA) of the rate of change (ROC) of market prices over specific periods.

Traders interpret it as a trend-following tool that identifies when a currency pair may be shifting from a bearish to a bullish trend.

How the Coppock Curve is Calculated

The Coppock Curve is a momentum-based indicator developed to identify long-term buying opportunities by measuring market sentiment. The calculation process involves three key steps, as outlined below:

1. Rate of Change (ROC)

The first step in calculating the Coppock Curve is to compute the Rate of Change (ROC) for two different time periods.

Traditionally, the periods used are 14 months and 11 months, although some traders may adjust these based on their strategy or market conditions.

The ROC measures the percentage change in price over a specified period, showing how much the price has increased or decreased compared to a previous point in time.

For the Coppock Curve, the 14-month and 11-month ROC calculations are designed to capture the longer-term price trends and potential shifts in market sentiment.

2. Weighted Moving Average (WMA)

After calculating the ROC values, the next step is to smooth the data using a 10-period Weighted Moving Average (WMA). The WMA gives more weight to recent data points, helping to smooth out short-term fluctuations and reduce market noise.

When the WMA is applied, the curve becomes more reliable for determining true trends rather than reacting to minor price volatility.

This smoothed value ensures that the Coppock Curve is less prone to false signals, especially in volatile Forex markets.

3. Summation

Finally, the smoothed ROC values from the two periods are added together to form the Coppock Curve. The result is plotted as a curve, which oscillates above and below a zero line.

A positive value of the Coppock Curve suggests a bullish market, indicating potential buy signals.

A negative value indicates bearish conditions, signalling that traders should be cautious of potential downtrends.

The entire process is designed to filter out short-term price movements and focus on the underlying long-term trend, making the Coppock Curve a popular tool for Forex traders looking to capture major market reversals.

How to Interpret the Coppock Curve in Forex

The primary use of the Coppock Curve is to identify buying opportunities in long-term downtrends. However, in the context of forex trading, it can serve both bullish and bearish signals.

1. Buy Signal

A buy signal is generated when the Coppock Curve turns upward after being below zero, indicating a shift in momentum from bearish to bullish.

This suggests that a currency pair is likely transitioning from a downtrend to an uptrend, making it a potential buying opportunity.

2. Sell Signal

While the Coppock Curve was not originally intended for selling signals, many traders use a downward turn from above zero as an indication that the uptrend may be weakening, signalling a potential reversal or bearish trend.

How to Apply the Coppock Curve in Forex Trading

In forex, traders primarily rely on the Coppock Curve to forecast long-term trends.

However, it can be used in conjunction with other indicators for more precision and confidence in trade entries and exits.

1. Pair with Trend Indicators

 The Coppock Curve works best when used alongside other trend-following indicators, such as moving averages or trendlines.

For example, if the Coppock Curve is signalling a buy, confirm this with a moving average crossover or a break above a key resistance level.

2. Confirm Market Bottoms

In a bearish market, wait for the Coppock Curve to turn upward from below zero. This is typically a strong signal that the market is ready to reverse. You can enter a long position once the curve has confirmed an uptrend.

3. Exit Strategy

 While the Coppock Curve is more useful for entry signals, traders can also monitor its movements for exits.

If the curve starts to plateau or turn downward from above zero, it might be time to consider taking profits, especially if combined with other bearish indicators.

Examples of the Coppock Curve in Forex

For instance, if you are analyzing the USD/JPY currency pair and the pair has been in a downtrend for several months, you notice that the Coppock Curve has started to turn upward from a negative value.

You pair this observation with other indicators, such as a bullish moving average crossover and a break above a key resistance level.

At this point, you might decide to enter a long position, anticipating that the USD/JPY is transitioning from a bearish to a bullish trend. 

Advantages of the Coppock Curve in Forex Analysis

1. Long-Term Focus

 The Coppock Curve is ideal for traders who prefer to focus on long-term trends rather than short-term volatility.

This makes it especially useful for position and swing traders who are more concerned with overall market direction than intraday movements.

2. Simplicity

 Despite its complex calculation, the Coppock Curve is easy to interpret. It provides clear signals, reducing the ambiguity that sometimes accompanies other technical indicators.

3. Adaptability

Though it was created for stock markets, the Coppock Curve has proven effective in forex markets as well. It can be customized to different time frames and currency pairs, making it versatile for various trading strategies.

Pitfalls of the Coppock Curve

While the Coppock Curve offers distinct advantages, it’s important to acknowledge its limitations:

1. Delayed Signals

 Like most trend-following indicators, the Coppock Curve tends to lag behind the market. As a result, traders may miss the very beginning of a new trend and experience delays in entering trades.

2. Not Ideal for Short-Term Trading

 The Coppock Curve is best suited for long-term trading strategies. Scalpers or day traders may find it less useful, as it does not provide frequent signals suitable for quick trades.

3. Lack of Sell Signals

 While traders can use the curve to identify potential bearish reversals, the Coppock Curve was originally designed as a buy-only indicator. Therefore, it’s important to use additional tools to confirm exit points or bearish trends.
