RSI Calculator
The 14-period Relative Strength Index, calculated from real price history.
What does RSI mean?
The Relative Strength Index (RSI) is a momentum indicator scored from 0 to 100. Readings above 70 are traditionally considered "overbought," suggesting a coin may be due for a pullback, while readings below 30 are considered "oversold," suggesting it may be due for a bounce. RSI works best combined with other signals rather than as a standalone trading rule.
Frequently Asked Questions
What is a good RSI value?
There is no single "good" value. Above 70 is traditionally read as overbought and below 30 as oversold, but strong trends can keep RSI in extreme territory for extended periods.
How is RSI calculated here?
This calculator uses the standard 14-period RSI formula based on the average size of recent up days versus down days, computed from real daily closing prices.
Should I trade based on RSI alone?
No. RSI is one momentum signal among many and works best combined with price trend, volume and other tools like the Radar and Volatility Tracker.
