What Is the RSI Trading Strategy?

Introduced by J. Welles Wilder, the Relative Strength Index (RSI) is a tool designed to track the intensity of price trends by analyzing momentum shifts within the market. It measures the speed and change of price movements and ranges between 0 and 100.

RSI Formula: RSI = 100 – (100 / (1 + RS))
RS (Relative Strength): Average gain of up periods during a specified time frame divided by the average loss of down periods.
Default Setting: The 14-period RSI remains the standard setting traders rely on for consistent momentum analysis.

How RSI Works?

Above 70: Suggests the asset may be overbought and a price correction could be on the horizon.
Below 40: Suggests that the asset is oversold and may be ready for a bounce.
50 Level: Often used as a middle line to judge bullish or bearish momentum.

RSI helps traders assess if a stock is potentially overvalued or undervalued.

Basic RSI Trading Strategy for Beginners

Buy Signal: When RSI crosses below 40 and then moves upward. Just because the RSI drops below 40 and then moves back up doesn’t mean it’s a buy signal. Always confirm it by combining with other indicators like Bollinger Bands, Confirmation Candle like(hammer, doji),Volume and Price Action.

Sell Signal: When RSI crosses above 70 and then turns downward. It’s not always right to sell just because RSI crosses above 70. Always confirm the signal by using it with other indicators.

Advanced RSI Strategies

1. RSI Divergence

Bullish Divergence: Price makes a lower low, but RSI makes a higher low.When this happens, the price is preparing to change its direction and is ready to move upward.

Bearish Divergence: When price hits a new high but RSI forms a lower low, it shows weakening momentum despite strong price action indicating a possible upcoming decline.

In RSI divergence, the fewer the price candles between the divergence points, the more powerful the signal tends to be.

2. RSI with Trendlines

When the price reaches a new high but the RSI forms a lower high, it signals fading momentum a warning that, despite the strong price action, a potential reversal to the downside may be near. This gives us an early signal whether the price will break out or break down, allowing you to catch the early movement.

3. RSI + Moving Averages

Use RSI to confirm signals from moving average crossovers. On the weekly chart, a bullish crossover occurs between the 20 EMA and 50 EMA. However, you can observe that the RSI had already given a bullish signal earlier by sustaining above the 60 level.

4. RSI + Volume

Pairing RSI with spikes in volume helps confirm the strength of price momentum. After the RSI crossed 60, there was a spike in volume, which indicates that the price is bullish. It’s also important that the candle where the volume spike occurs is followed by another candle with continued volume, which confirms the bullish signal.

Common Mistakes to Avoid When Using RSI Trading Strategy

Relying Solely on RSI for Buy/Sell Decisions
- Mistake: Acting just because RSI crosses above 70 (overbought) or below 40 (oversold).
- Fix: Always combine RSI with other indicators like volume, trendlines, candlestick patterns, or moving averages for confirmation.
Ignoring Market Context (Trend)
- Mistake: In strong trending markets, the RSI can linger in overbought or oversold territories for a prolonged time.
- Fix: Identify the overall market trend first (uptrend/downtrend/sideways) and use RSI accordingly. During a bullish trend, the RSI commonly remains above the midpoint level of 50.
Misinterpreting RSI Divergence
- Mistake: Entering a trade solely based on divergence without any confirmation. Divergence can last longer than expected.
- Fix: Confirm divergence signals with price action or other tools like support/resistance levels or volume analysis.
Forgetting Timeframe Alignment
- Mistake: Using RSI on one timeframe without checking higher/lower timeframes.
- Fix: Align RSI signals across multiple timeframes (e.g., confirmation on daily if you’re trading hourly) to improve accuracy.
Overcomplicating RSI with Too Many Indicators
- Mistake: Overloading your analysis by mixing RSI with numerous other indicators can cause decision-making paralysis.
- Fix: Keep your strategy focused and backtest combinations that work well together (e.g., RSI + Volume or RSI + EMA).
Chasing Spikes Without Follow-Through
- Mistake: Acting on volume spike or RSI breakout without checking if the next candle confirms the move.
- Fix: Always wait for follow-up volume and candle structure before entering, as you rightly pointed out in the “RSI + Volume” section.
Overtrading Based on Every RSI Move
- Mistake: Taking trades every time RSI hits 40 or 70.
- Fix: Focus on high-quality setups and use RSI as a filter, not a trigger on its own.

Conclusion

The RSI trading strategy is a powerful and versatile tool when used properly. From simple overbought/oversold signals to advanced divergence setups, RSI can offer meaningful insights. The key is to avoid using it in isolation and to focus on confirmation with other tools. Whether you’re just starting or refining your trading system, mastering RSI can enhance your decision-making and results.

Frequently Asked Questions (FAQs)

What is the ideal RSI setting for beginners?

The default 14-period RSI is the most commonly used setting and is a good starting point for beginners. It provides a balanced view of momentum and works well across different assets and timeframes.

Is RSI reliable for trading on its own?

No. While RSI is a powerful indicator, it should not be used in isolation. Combine it with volume, trendlines, candlestick patterns, or moving averages to increase accuracy and reduce false signals.

What is the difference between overbought and oversold in RSI?

Overbought (RSI > 70): Asset may be due for a pullback or reversal.
Oversold (RSI < 40): Asset may be ready for a bounce.
These are signals to watch, not immediate buy/sell triggers.

How does RSI divergence help in trading?

RSI divergence occurs when price moves in the opposite direction of RSI.
Bullish divergence signals a possible upward reversal.
Bearish divergence hints at a potential downward move.
Use divergence along with price confirmation for better reliability.

Can RSI be used in intraday trading?

Yes. RSI can be applied on lower timeframes (e.g., 5-min, 15-min charts), but be aware that it becomes more sensitive and may generate more false signals. Always check higher timeframe confirmation before acting.

What does it mean when RSI crosses above 60 with volume spike?

When RSI crosses above 60 and is accompanied by a volume spike, it’s a strong bullish signal. If the following candle also shows strong volume, it confirms momentum and increases the probability of a price breakout.
