What is the Relative Strength Index (RSI)

RSI, or Relative Strength Index, is a momentum oscillator utilized in trading to assess the velocity and magnitude of recent price movements, helping to identify overbought or oversold conditions in a financial instrument. It is presented as a line chart on a scale ranging from 0 to 100, where values above 70 typically signal that an asset is overbought, and readings below 30 indicate it is oversold.

Key Takeaways (RSI Indicator)

  • The RSI is a momentum oscillator indicating when assets are overbought or oversold.

  • It assists in identifying trend reversalstrend strength, and optimal entry and exit points.

  • It is most effective when combined with tools such as moving averagesFibonacci retracement levelsMACD, and trendlines.

  • Traders should always consider market context and implement risk management practices.

  • The RSI performs well across forexequities, and commodities, making it a versatile indicator for all traders.

How the RSI Indicator Works

The Relative Strength Index (RSI) is a widely utilized momentum oscillator that measures the velocity and magnitude of price movements. It calculates the ratio of recent average gains to average losses over a specified period, typically 14 bars. This straightforward yet powerful indicator helps traders identify overbought and oversold market conditions, potential trend reversals, and confirm trend strength.

Here’s the methodology:

RSI Calculation Formula:

RSI = 100 - (100 / (1 + RS))
Where 
RS (Relative Strength) = Average Gain over N periods ÷ Average Loss over N periods

This yields a value ranging from 0 to 100:

  • Above 70: Indicates the asset may be overbought , signaling a possible price correction.

  • Below 30: Suggests the asset may be oversold, implying a potential upward price adjustment.

  • Between 30–and 70: Considered a neutral zone where traders often seek additional confirmation signals.

Example: If a stock’’s RSI surpasses 70, it may be deemed overbought, increasing the probability of a price decline. Conversely, if RSI falls below 30, the stock could be oversold and poised for a rebound.

RSI Indicator in Forex, Equities, and Commodities 

The RSI indicator is effective across multiple asset classes:

Forex Trading:

Equity Trading:

  • RSI helps identify stocks that are overextended or undervalued based on recent price movements.

  • A stock consistently showing RSI above 70 may indicate overheating, while readings below 30 could signal undervaluation and buying opportunities.

Commodity Trading:

  • Commodities such as goldBrent crude oil, and silver follow pronounced cyclical patterns. RSI helps identify potential cycle shifts.

  • Example: An RSI above 70 during a gold rally may signal an opportune moment to take profits.


Confirming Trends with the RSI Indicator

RSI is valuable not only for timing entries and exits but also for confirming trend strength.

  • In Uptrends: RSI typically remains above 50, supporting bullish momentum.

  • In Downtrends: RSI often stays below 50, confirming bearish momentum.

Example: During a sustained EUR/USD uptrend, RSI holding above 50 reinforces the case for maintaining long positions.


RSI Divergence: A Strong Signal

Divergences between price action and RSI can signal weakening trends or imminent reversals.

  • Bearish Divergence: Price forms higher highs while RSI forms lower highs, indicating waning momentum and a potential sell-off.
  • Bullish Divergence: Price makes lower lows while RSI makes higher lows, suggesting bearish momentum is fading and a reversal may be near.

Example: If GBP/USD hits a new low but RSI does not, traders might look for a bullish reversal setup.

Combining the RSI Indicator with Other Indicators

How to combine RSI with other indicators?

The RSI becomes more effective when used alongside complementary technical tools.

  • RSI + Moving Averages: An RSI overbought signal near resistance from a 200-day moving average can strengthen the case for entering a short position.

  • RSI + Fibonacci Retracement: An oversold RSI at the 61.8% Fibonacci retracement level may indicate a high-probability buying opportunity.

  • RSI + Trendlines: Confirm RSI signals with bounces or breaks of well-established trendlines.

  • RSI + Bollinger Bands: Identify volatility expansions or contractions in conjunction with RSI levels.

  • RSI + MACD: Use RSI to gauge momentum strength and MACD (Moving Average Convergence Divergence) for crossover confirmations.

Common RSI Indicator Pitfalls to Avoid

Overreliance on RSI:

Traders relying solely on RSI may encounter false signals. RSI should be integrated into a comprehensive strategy that includes trend analysis, support and resistance levels, and volume confirmation.

Ignoring Market Context:

In strong trending markets, RSI can remain in overbought or oversold zones for extended periods. Context is crucial——do’ not blindly sell just because RSI crosses 70 during a bullish trend.

Inadequate Risk Management:

RSI signals are not guarantees. Always employ stop-loss orders and appropriate position sizing. For example, an RSI overbought signal combined with a short position should include a stop-loss above recent swing highs.
