RSI Divergence — what it is and how to use it in trading
Definition
An RSI divergence is a mismatch between price and the RSI indicator across two neighboring lows (or highs): price sets a new extreme while RSI, on the same bars, does not. In a bullish divergence, price makes a lower low while RSI forms a higher low than its previous one.
How it works in the builder
rsi_bullish_divergence/rsi_bearish_divergence are boolean operands with a period parameter (for the RSI calculation itself) and left/right (confirming the two compared swings). The signal is 1 on the bar confirming the second extreme — with the same kind of delay as a plain swing.
What it looks like on the chart
On the chart a divergence is marked with two trendlines: one connecting the two price extremes, another connecting the matching points on the RSI panel. The lines pointing in opposite directions is the divergence itself.
Typical use
A sign the current move is losing steam and may reverse — price is still falling, but with weakening momentum. Typical condition: rsi_bullish_divergence == 1 combined with a higher-timeframe trend filter (e.g. ema(50) rising) to avoid catching divergences against a strong downtrend.
Common pitfalls
Divergences are one of the most subjective signals in technical analysis — in a strong trend the mismatch can persist for several bars before price finally reverses (or never reverses at all). Using it as the sole entry condition is risky; it usually needs extra confirmation from structure or a candlestick pattern.
