How to Use the Relative Strength Index (RSI) in Crypto
The Relative Strength Index (RSI) is one of the most widely used tools for analyzing short-term market momentum. It measures a cryptocurrency’s recent trading strength by assessing the pace and direction of its price movements. This makes it an invaluable tool for timing trades and spotting swing trading opportunities.

How to Read the RSI
The RSI is expressed as a percentage, moving between 0 and 100. It is typically displayed as a graph below the price chart, with two parallel lines marking the overbought and oversold levels. A line moves within this channel, signaling the market’s momentum.
Oversold: When persistent selling pressure causes the RSI to drop below certain thresholds, traders often anticipate an upward rally.
Overbought: Conversely, when a cryptocurrency has been heavily bought, the RSI indicates that a downward correction may be imminent.
While shorter timeframes can reveal short-term opportunities, analyzing the RSI over several weeks or longer provides a more comprehensive understanding of its reliability in predicting price trends.
When Is the Market Overbought or Oversold?
The RSI framework, developed by J. Welles Wilder, includes standard thresholds to define overbought and oversold conditions:
Below 30: Indicates an oversold market, often signaling a potential price rise.
Above 70: Indicates an overbought market, often signaling a potential price decline.
Adjusting RSI Levels
Custom Levels: For some cryptocurrencies, levels like 20 (oversold) and 80 (overbought) may provide more accurate signals.
Market Conditions: RSI levels can vary depending on whether the market is bullish or bearish:
Bull Market:
Below 40: Oversold, signaling potential price increases.
Above 90: Overbought, signaling potential price declines.
Bear Market:
Below 10: Oversold, signaling potential price increases.
Above 60: Overbought, signaling potential price declines.
Key Reminder
The RSI is just one tool among many in technical analysis. It does not guarantee price movements. For example, during strong trends, prices may continue to rise or fall even when the RSI indicates overbought or oversold conditions.
How to Use the RSI for Crypto Trading
- Entry and Exit Points
Traders use RSI to determine when to buy low and sell high. For instance:
Buy: When the RSI dips below 30.
Sell: When the RSI rises above 70.
Swing Trading
Swing trading involves capitalizing on short-term price fluctuations. Traders may buy when the RSI crosses below 30 and sell when it crosses above 70. This strategy can also include short positions during declines.Identifying Support and Resistance Levels
The RSI helps identify support and resistance zones that may not yet be visible on the price chart.
Support: The price level that the market struggles to drop below.
Resistance: The price level that the market struggles to exceed.
Combining RSI analysis with price charts makes these zones easier to identify.
- Bullish and Bearish Divergences
Bullish Divergence: Occurs when the price forms higher lows, but the RSI forms lower lows. This often signals an upcoming price increase, especially if the RSI is in the oversold zone.
Bearish Divergence: Occurs when the price forms higher highs, but the RSI forms lower highs. This may signal a potential price decline.
How to Calculate the RSI
Although RSI calculations can be complex, the formula provides insight into how it works:
RSI = 100 – [100 / (1 + (Average Gain over n days / Average Loss over n days))]
Most platforms, such as TradingView, automatically calculate the RSI and display it on charts, simplifying the process for traders.
