What is the RSI, or Relative Strength Index?

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

Key Takeaways (RSI Indicator)

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

  • It assists in identifying reversal pointstrend strength, and optimal entry and exit levels.

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

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

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

How the RSI Indicator Works

The Relative Strength Index (RSI) is a widely adopted momentum oscillator that quantifies the velocity and magnitude of price changes. It calculates the ratio of recent average gains to average losses over a specified period, typically 14 intervals. This straightforward yet powerful tool helps traders detect overbought and oversold conditions, potential trend reversals, and confirm trend direction.

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 formula yields a value between 0 and 100:

  • Above 70: Signals that the asset may be overbought and could be poised for a price correction.

  • Below 30: Indicates the asset may be oversold, suggesting a possible upward price adjustment.

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

Example: If a stock’’s RSI exceeds 70, it may be regarded as overbought, increasing the probability of a price pullback. Conversely, if the RSI falls below 30, the stock could be oversold and primed for a rebound.

RSI Indicator in Forex, Equities, and Commodities 

The RSI indicator is effective across various asset classes:

Forex Trading:

  • The forex market experiences continuous price fluctuations. RSI helps identify when currency pairs are overbought (above 70) or oversold (below 30).

  • Example: If the EUR/USD RSI surpasses 70, traders might anticipate a potential reversal or consolidation.

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 below 30 could signal undervaluation and buying opportunities.

Commodity Trading:

  • Commodities such as goldBrent crude oil, and silver exhibit strong cyclical behavior. RSI helps identify potential cycle shifts.

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


Confirming Trends with the RSI Indicator

The 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, an 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 impending reversals.

  • Bearish Divergence: Price makes higher highs while RSI forms lower highs, indicating diminishing momentum and a potential sell-off.
  • Bullish Divergence: Price makes lower lows while RSI forms higher lows, suggesting weakening bearish momentum and a possible reversal.

Example: If GBP/USD records a new low but RSI fails to do so, traders may anticipate a bullish reversal setup.

Combining the RSI Indicator with Other Indicators

How to combine the RSI Indicator with other tools?

The RSI’s effectiveness increases when used alongside complementary indicators.

  • RSI + Moving Averages: An overbought RSI signal near a 200-day moving average resistance can reinforce a short trade setup.

  • 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 readings.

  • RSI + MACD: Use RSI to gauge momentum strength, while MACD (Moving Average Convergence Divergence) provides crossover confirmation.

Common RSI Indicator Mistakes to Avoid

Overreliance on RSI:

Traders relying solely on RSI risk false signals. RSI should be integrated within a comprehensive strategy including trend analysis, support and resistance levels, and volume confirmation.

Ignoring Market Context:

In strong trending markets, RSI can remain in overbought or oversold territory for prolonged periods. Context is crucial——don’t automatically sell just because RSI crosses 70 in a bullish trend.

Poor Risk Management:

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