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
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.
