What Is RSI (Relative Strength Index)?
RSI, the Relative Strength Index, is a momentum indicator that measures the speed and size of recent price changes on a scale from 0 to 100. Readings above 70 are conventionally called overbought and readings below 30 oversold.
Why RSI matters
RSI condenses momentum into a single number that is comparable across coins and timeframes. It will not predict the future by itself, but it reliably flags stretched conditions: markets that have moved too far, too fast in one direction and are statistically more likely to pause or revert.
How traders use it
Beyond the classic 70/30 thresholds, traders watch RSI divergence (price makes a new low while RSI makes a higher low) as a reversal signal, and use different timeframes for different styles: 5 minute RSI for scalps, 4 hour and daily RSI for swing entries. Oversold on a high timeframe plus a momentum shift on a low one is a common entry recipe.
