The concept of divergence has always been popular in the financial market. According to the popular Merriam-Webster dictionary, one definition of divergence is the process of moving away from the course or standard.

In trading, it refers to a situation when the price of an asset moves in the opposite direction to the indicator. In this article, you will learn what a divergent is, how to spot one, types of divergences, and the rules you need to follow when using the strategy.

What is a divergence in trading?

Divergence can be seen in different ways in the financial market. For example, when using technical indicators, it can be defined as a period when the price of an asset is moving in one direction while indicators are guiding for the opposite to happen.

For example, a currency pair may be rising even as the Relative Strength Index (RSI) starts to decline from its extreme overbought levels. In most cases, when this happens, it is usually a signal that the original trend of an asset is starting to wane.

In the chart below, we see that the Relative Strength Index is falling even as the EUR/USD pair holds steady.

From the fundamental perspective, divergence is viewed as a period when the shares of a company are not in line with its intrinsic data. For example, the stock of a company may continue dropping even after reporting relatively strong economic numbers.

A good example is what happened to Intel in 2020. The stock cratered by more than 20% even after the firm continued to beat analysts forecasts.

Types of divergences

Broadly, there are two main types of divergences in trading:

  • Bullish divergence

For starters, a bull is a trader or investor who hopes that the price of an asset will continue rising. A bullish divergence, therefore, happens when the price of an asset is falling even as one or more indicator starts to signal a potential upward trend.

This divergence can happen in all types of assets, including forex, shares, and commodities. The chart below is a good example of a bullish divergence.

  • Bearish divergence

A bearish divergence is the exact opposite of a bullish divergence. It happens when the price of an asset continues to fall even as the indicator starts to rise.

How to trade divergences

In all fairness, trading divergences is a relatively difficult thing, especially for new traders. That’s because divergences don’t provide an initial signal of when to buy or when to sell. Still, you can use several indicator-specific strategies to trade these divergences.

Trading divergencies using the MACD

The Moving Average Convergence and Divergence (MACD) is one of the popular indicators used to show divergences in the market. The MACD is derived by subtracting a shorter moving average period from a longer one.

The most popular periods are the 26-day and 12-day moving averages. The signal line is usually the 9-day moving average. In other words, the MACD converts the normal moving averages into an oscillator.

Ideally, trading signals in MACD happen when the two lines make a crossover. If it happens below the neutral line, it is usually a bullish signal. Also, if it happens above the neutral line, it is usually a bearish signal.

A bullish divergence in MACD happens when the price of an asset forms a lower low while the MACD forms a higher low. In this case, the lower low will affirm the current trend but the higher low in the indicator will signal a loss of strength.

Similarly, a bearish divergence forms when the price of an asset forms a higher high while the MACD forms a lower high. The chart below shows a bearish divergence on the Alphabet stock.

Using the RSI to trade divergencies

Another approach of trading divergencies is using the Relative Strength Indicator (RSI). For starters, this indicator is one of the most popular indicators in the world today. It is typically used to identify overbought and oversold levels.

The indicator is calculated by first adding the gains and losses in a certain period and then finding the average gains and losses.

In most cases, a buy signal emerges when the index falls to below 30, which is the oversold level while a sell signal emerges when the RSI is above 70. Therefore, a divergence emerges when the RSI is rising while the price is falling, and vice versa.

The chart below shows a divergence that formed on the GOOG chart.

Identifying divergences using Stochastic oscillator

Another approach of identifying divergencies is using the stochastic oscillator. For starters, the stochastic oscillator is also a popular two-lined indicator that identifies overbought and oversold situations.

A bullish trend emerges when the two lines make a crossover below the lower line and continue rising. The vice versa is also true.

The chart below shows a bullish divergence on the GOOG chart. As you can see, while the share price is dropping, the two lines of the Stochastic oscillator are rising.

There are other popular strategies of trading divergencies. Some of the other popular indicators you can use are momentum, the relative vigour index, and the divergence indicator that is in MetaTrader.

Final thoughts

Trading divergences is one of the many trading strategies that professional traders use to make money. Indeed, it is a widely-used approach, especially among the experienced Wall Street titans. All you need to do to trade it well is to identify the indicators you will use, understand them, and then practice using a demo account.
