An indicator divergence strategy uses a mismatch between price movement and oscillator movement as a signal that the current trend is quietly weakening. Divergence is considered one of the strongest signals in technical analysis, since it reveals a shift in market dynamics before it becomes obvious in price itself.
What divergence is
Divergence occurs when price and an indicator move in opposite directions or with different intensity. For example, if price sets a new high but an oscillator (such as RSI or MACD) doesn't confirm it with its own new peak, that suggests the move's momentum is weakening even as price keeps rising.
Regular divergence
Regular (classic) divergence signals a possible trend reversal:
- Bearish divergence — price forms a higher high while the indicator forms a lower one, pointing to weakening upward movement.
- Bullish divergence — price forms a lower low while the indicator forms a higher one, pointing to weakening downward movement.
Regular divergence is more often used to find exit points from a trend or entry points against it on a reversal.
Hidden divergence
Hidden divergence, unlike the regular kind, signals not a reversal but a continuation of the existing trend after a pullback:
- Bullish hidden divergence — price forms a higher low on a pullback while the indicator forms a lower one, pointing to the strength of an uptrend.
- Bearish hidden divergence — price forms a lower high on a pullback while the indicator forms a higher one, confirming the strength of a downtrend.
Hidden divergence is useful for traders who follow the trend and look for entries on pullbacks, as described in the article on the trend-following strategy.
Which indicators to use for finding divergence
Divergence can be looked for with nearly any oscillator, but RSI, MACD and the Stochastic Oscillator are most common — these give sufficiently clear peaks and troughs to compare against price movement. Divergence also applies to volume indicators, covered in detail in the article on the volume-based strategy.
How to confirm a divergence signal
Divergence by itself is a warning signal, not a precise entry trigger. Before opening a trade, it's recommended to wait for additional confirmation: a break of a local trend line, a reversal candlestick pattern forming, or a moving average crossover in the direction of the divergence.
Common mistakes working with divergence
A common mistake is confusing regular and hidden divergence and opening a trade in the wrong direction. Another is looking for divergence on too short a chart segment, where random fluctuations in price and the indicator create a false sense of discrepancy.
Automating divergence detection
Comparing price and indicator peaks and troughs can be formalized into an algorithm. A trading robot for Pocket Option can automatically find divergence and check additional confirmation conditions — details on the features page.
Conclusion
An indicator divergence strategy lets you spot weakening or strengthening momentum before it becomes obvious in price itself. Tell regular and hidden divergence apart, confirm the signal with additional factors, and avoid hunting for divergence on too short a segment. Automatic detection is available in the robot's plans.
