FAQ
How is RSI calculated?›
RSI is calculated using the formula: RSI = 100 - (100 / (1 + RS)), where RS is the average gain divided by the average loss over the lookback period. The standard period is 14. After the initial average, a smoothed (Wilder's) average is applied.
What RSI values indicate overbought or oversold conditions?›
Traditionally, an RSI above 70 indicates overbought conditions (potential sell signal), while an RSI below 30 indicates oversold conditions (potential buy signal). Some traders use 80/20 for stronger signals.
