The RSI Trading Strategy: Overbought, Oversold, and Divergence

What Is the RSI?

The Relative Strength Index (RSI) is a momentum oscillator that measures the speed and magnitude of price changes. It ranges from 0 to 100 and was developed by J. Welles Wilder Jr. in 1978.

Default Settings

• Period: 14 (standard)
• Overbought: Above 70
• Oversold: Below 30

Beyond Overbought/Oversold

Many traders use RSI incorrectly — buying every time it dips below 30 and selling above 70. In strong trends, RSI can remain overbought or oversold for extended periods. Instead, use trend context:

• In uptrends: RSI ranges between 40-80. Buy when RSI pulls back to 40-50.
• In downtrends: RSI ranges between 20-60. Sell when RSI bounces to 50-60.

RSI Divergence: The Most Powerful Signal

Regular (Classic) Divergence

Bullish divergence: Price makes a lower low, but RSI makes a higher low. This signals weakening selling pressure and a potential reversal up.

Bearish divergence: Price makes a higher high, but RSI makes a lower high. This signals weakening buying pressure and a potential reversal down.

Hidden Divergence

Bullish hidden divergence: Price makes a higher low, but RSI makes a lower low. This signals trend continuation upward.

Bearish hidden divergence: Price makes a lower high, but RSI makes a higher high. This signals trend continuation downward.

Multi-Timeframe RSI

Align RSI readings across timeframes for higher-probability trades:

1. Check RSI on the daily chart for overall bias
2. Use the 4-hour RSI for trade direction
3. Time entries on the 1-hour RSI
