This guide explains the types of RSI divergence, rules you can test, a worked example on Nifty, the confirmation that matters and how to define divergence clearly enough to automate.
At a glance
| RSI divergence strategy | |
|---|---|
| Type | Reversal |
| Indicator | RSI(14) |
| Markets | Nifty and Bank Nifty futures, liquid stocks, MCX futures |
| Timeframes | 15-minute to daily |
| Long setup | Price makes a lower low, RSI makes a higher low, first low below RSI 30 |
| Short setup | Price makes a higher high, RSI makes a lower high, first high above RSI 70 |
| Entry | Price breaks the swing between the two lows (or highs) |
| Stop | Beyond the second low (or high) |
| Target | The previous swing, or 2 times the risk |
Types of RSI divergence
| Type | Price | RSI | What it suggests |
|---|---|---|---|
| Regular bullish | Lower low | Higher low | A downtrend is losing strength |
| Regular bearish | Higher high | Lower high | An uptrend is losing strength |
| Hidden bullish | Higher low | Lower low | An uptrend is likely to continue |
| Hidden bearish | Lower high | Higher high | A downtrend is likely to continue |
Regular divergence is used to time reversals. Hidden divergence is used to join a trend on a pullback. This guide focuses on regular divergence. For how RSI itself is calculated, see the RSI indicator guide.
The rules
Bullish divergence
- First low: the price makes a swing low with RSI(14) below 30.
- Second low: within 5 to 30 candles, the price makes a lower low while RSI makes a higher low.
- Trigger: the price closes above the highest point between the two lows.
- Stop: below the second low.
- Target: half at 2 times the risk, the rest on a trailing stop.
Bearish divergence
The mirror image, with the first high above RSI 70 and a trigger below the lowest point between the two highs.
A worked example
On a 15-minute Nifty futures chart, the price falls to a swing low of 24,880 with RSI at 24. It bounces to 24,960, then falls to a new low of 24,850. RSI at the second low is 33: higher than at the first low, although the price is lower.
- Trigger: a close above 24,960, the high between the two lows
- Entry: 24,965
- Stop: 24,840, below the second low, a risk of 125 points
- Target: 2 times the risk, 25,215
One lot of 65 risks ₹8,125 for a target of ₹16,250. These numbers illustrate the rules, not a result.
Why confirmation matters
A divergence can form, then form again, while the price keeps falling. Strong trends often show two or three divergences before they turn. Waiting for the price to break the swing between the two lows filters out many of these. The trade enters later and gives up some of the move, but loses less often.
Defining divergence for automation
Divergence is easy to see on a chart afterwards and hard to define in rules. To test or automate it:
- Define a swing low: a candle whose low is lower than the lows of 3 candles on each side. This needs 3 candles after the low before it is confirmed.
- Compare the last two swing lows within a set window, such as 5 to 30 candles apart.
- Check RSI at those two candles.
The 3 candles after the swing are a delay that a backtest must respect. A test that "knows" a low is a swing low at the moment it forms has look-ahead bias.
When the strategy works, and when it does not
Works best when:
- The price reaches a known level, such as prior support and resistance strategy, with a divergence.
- The move has run a long way and volatility is rising into the second low.
Struggles when:
- A strong trend keeps going. Divergences can stack up while the price trends.
- News drives the move. Divergence reads momentum, not fundamentals.
- The swings are too close together, which makes the RSI readings almost the same.
Automating an RSI divergence strategy
In QuantPower's strategy builder, set the swing rule and the RSI comparison as conditions, the trigger as a stop order above the swing high, and the stop below the second low. Add a market alert if you want to review each divergence before the order goes in. Test it in paper trading first.
Backtesting an RSI divergence strategy
- Test the swing definition (2, 3 or 5 candles each side) and the window between swings.
- Compare entries on the trigger with entries at the second low. The difference shows what confirmation is worth.
- Count how often divergences failed in strong trends.
See RSI mean reversion for a simpler RSI strategy to compare against.
Common mistakes
- Entering on the divergence alone. Without a trigger, the strategy buys into falling markets.
- Seeing divergences that are not there. Fix the swing rule and stick to it.
- Ignoring the timeframe. A divergence on a 5-minute chart means little against a daily downtrend.
Frequently asked questions
What is RSI divergence?
A difference between the direction of the price and the direction of the RSI, such as a lower low in price with a higher low in RSI.
Is RSI divergence reliable?
It is a warning that momentum is fading, not a signal on its own. Use a price trigger and a stop.
What is the difference between regular and hidden divergence?
Regular divergence points to a reversal. Hidden divergence points to a trend continuing after a pullback.
Which RSI setting is best for divergence?
RSI(14) is the standard. Shorter settings give more divergences and more false ones.
