Do you have a favorite momentum oscillator? While there are many options, the Relative Strength Index (RSI) has been a top choice among day and swing traders since its creation by J. Welles Wilder Jr. in 1978. This versatile tool measures price momentum and identifies potential reversals, but mastering it requires more than just oversold/overbought signals. Let’s dive deeper into effective RSI trading strategies.
What Is the RSI Indicator?
The Relative Strength Index (RSI) is a momentum oscillator that gauges the speed and direction of price movements. It fluctuates between 0 and 100, with key thresholds at 30 (oversold) and 70 (overbought). These levels help traders spot potential reversals when an asset deviates from its perceived "true" value.
Key Components of the RSI:
- Percentage Range (0–100%): Identifies overbought/oversold conditions.
- RSI Line: Tracks price momentum shifts.
- Centerline (50%): Acts as a pivot—bullish above, bearish below.
In uptrends, the RSI typically stays between 40–90, with the 50% line as support. During downtrends, it ranges from 10–60, with the centerline as resistance. Adjusting the RSI’s period (default: 14 days) can smooth oscillations for different timeframes.
Trading Strategies Using the RSI
1. Divergence: Spotting Reversals
Divergence occurs when price and the RSI move in opposite directions, signaling potential trend reversals.
Bullish (Positive) Divergence
- Setup: RSI forms higher lows while price makes lower lows (from oversold >30%).
- Implication: Selling pressure weakens; consider a long entry.
Bearish (Negative) Divergence
- Setup: RSI prints lower highs as price hits higher highs (from overbought <70%).
- Implication: Buying momentum fades; potential short opportunity.

2. Swing Rejections: Trading Momentum Shifts
This strategy focuses solely on RSI levels, ignoring price action.
Bullish Swing Rejection
- Trigger: RSI rebounds from 30% support after breaking out, forming a higher low.
- Action: Enter a long position.
Bearish Swing Rejection
- Trigger: RSI fails to reclaim 70% resistance after breaking down.
- Action: Initiate a short trade.
Pro Tips for RSI Trading
- Align with the Trend: Avoid counter-trend trades (e.g., bearish rejections in uptrends).
- Combine Indicators: Pair RSI with tools like MACD or candlestick patterns for confirmation.
- Avoid False Signals: Assets can stay overbought/oversold for extended periods—patience is key.
