Divergences: when price and momentum stop telling the same story

You now know the RSI, the stochastic and the MACD. Their most powerful use is not reading 70 or 30, but comparing how they behave with how price behaves. When the two move together, the trend is healthy. When they start to contradict each other, something is changing beneath the surface. That disagreement is called a divergence.

How a divergence works

In a healthy uptrend, each new high in price comes with a new high in the oscillator: momentum keeps up. If price makes a higher high but the RSI makes a lower high, the rally appears to continue, but with less force. It is like a car still climbing the hill with the pedal to the floor, but more and more slowly.

1. Spot two recent, clear highs (or two lows) on price.
2. Look at the oscillator's highs (or lows) on exactly the same candles.
3. Compare the two slopes: if they point in opposite directions, there is a divergence.
4. Check that the two points are close enough in time, usually between 5 and 30 candles apart.

Bearish divergence

A regular bearish divergence forms in an uptrend: price makes a higher high, the oscillator a lower high. Buyers still manage to push price up, but with less energy on each attempt. It carries more weight at major resistance or on a higher timeframe.

Bullish divergence

A regular bullish divergence is the mirror image: in a downtrend, price makes a lower low, the oscillator a higher low. Sellers still manage to push price down, but the pressure is fading. At major support, after a long decline, it is a serious clue that the move is running out of steam.

Regular or hidden

There is a second, less well-known type of divergence: the hidden divergence. It does not signal exhaustion, but a possible continuation of the trend. It shows up during pullbacks.

A simple way to tell them apart: a regular divergence is read on the extremes that extend the trend (new highs in an uptrend), a hidden divergence on the pullbacks that respect it (higher lows in an uptrend). Hidden divergences are traded in the direction of the trend, which often makes them more comfortable for a beginner.

Wait for confirmation

This is the most important rule in this lesson. A divergence can last a long time. In a powerful rally, you can see three or four bearish divergences in a row while price keeps climbing. Selling at the first one means fighting the trend on nothing more than a suspicion.

• Break of structure: for a bearish divergence, a close below the intermediate low between the two highs.
• Candlestick pattern: a bearish engulfing or an evening star on the second high.
• Oscillator crossover: for example the MACD crossing below its signal line.
• Key level: the divergence appears at a resistance or support you have already identified.

The more elements line up, the more solid the scenario. And even then, place your stop beyond the last extreme: if price makes a new high after you sell, your analysis is invalidated and you get out without arguing.

A few mistakes come up again and again among beginners. The first is comparing points that don't match: the oscillator's high must sit on the same candle, or nearly, as price's high. The second is connecting two highs that are too far apart in time, separated by several intermediate moves. The third is hunting for divergences on very small timeframes, where they keep appearing and disappearing. On H4 and D1 they are rarer, but far more significant.

Train your eye

Divergences are easy to see in hindsight and much harder to read live. The best training is to replay a chart candle by candle, without knowing what comes next, and note your decisions. The exercise below lets you do exactly that: spot the divergence, wait for your confirmation, then compare with what actually happened.
