Spotting Divergence

Divergence is price and momentum telling different stories

Divergence happens when price and a momentum indicator move in opposite directions at a swing point. Price makes a new low, but RSI or MACD makes a higher low. The new price extreme was reached with less momentum behind it than the previous one, which is a change in the character of the move even though price itself has not turned.

The distinction that matters is between what divergence describes and what people want it to predict. It describes a measurable fact about the last two swings. It predicts nothing. A trend can print divergence three times and continue, because fading momentum is a condition, not a schedule.

Regular divergence, at highs and lows

• Regular bullish divergence. Price prints a lower low, the indicator prints a higher low. Selling pressure is weakening even though price is still falling. Watched at the end of a downtrend.
• Regular bearish divergence. Price prints a higher high, the indicator prints a lower high. The advance is being made with less thrust. Watched at the end of an uptrend.

Hidden divergence points the other way

Hidden divergence is the same comparison with the roles swapped, and it is read as continuation rather than reversal. In an uptrend, price makes a higher low while the indicator makes a lower low. Price held up better than momentum did, which is what a shallow pullback inside a strong trend looks like.

This is worth learning properly because it resolves a common confusion. Someone looking for reversals will see the indicator making a lower low, call it weakness, and short into an intact uptrend. The same picture, read as hidden divergence, says the opposite. Which reading applies depends on the structure, which is why the structure has to be settled first.

Bullish divergence, step by step

EUR/USD falls to 1.0740 with RSI at 21. It bounces to 1.0820, then falls again to 1.0715, a new low by 25 pips. This time RSI reads 29. Price went lower, momentum did not. That is regular bullish divergence.

Here is what it does not give you. It does not give you an entry, because price has not turned. It does not give you a stop, because the divergence has no invalidation price of its own. What it gives you is a reason to watch 1.0820, the high between the two lows, because a break above it would be the structural event that the divergence was hinting at. The stop then goes beneath 1.0715, the distance is about 110 pips from a 1.0825 entry, and the position size calculator converts that into a lot size. The divergence started the process. Structure finished it.
