Relative Strength Index (RSI)
Web3 / technical analysis
The Relative Strength Index is a momentum oscillator that quantifies the magnitude and speed of price changes to identify overbought conditions (typically above 70) or oversold conditions (typically below 30) in cryptocurrency markets. Calculated on a 0-100 scale using the average of recent gains compared to recent losses over a specified period (commonly 14 periods), the RSI reveals when an asset's price movement may have become extended in one direction. Traders use RSI divergences—where price makes a new high but RSI does not—as warning signals that momentum may be weakening and a reversal could be imminent. Example: In May 2021, when Dogecoin's RSI climbed above 90 following Elon Musk's SNL appearance, experienced traders recognized the extreme overbought condition as a warning signal, and the coin subsequently corrected sharply within days. Why it matters for crypto technical analysis: RSI provides quantifiable signals for potential reversals and helps traders avoid buying at local tops or selling at local bottoms, critical for managing risk in crypto's notoriously volatile 24/7 trading environment.
