RSI (Relative Strength Index) Calculator
The Relative Strength Index (RSI) is a popular momentum oscillator used by traders to measure the speed and change of price movements. It helps identify overbought or oversold conditions of an asset.
RSI values range from 0 to 100, where values above 70 typically indicate overbought conditions, and below 30 suggest oversold conditions.
Formula
RSI is calculated using the formula:
RSI = 100 − [100 ÷ (1 + RS)]
Where RS (Relative Strength) = Average Gain ÷ Average Loss
- Average Gain: The average of all positive price changes over a specified period.
- Average Loss: The average of all negative price changes over the same period.
How to Use the RSI Calculator
- Calculate or input the Average Gain over your chosen period (usually 14 days).
- Enter the Average Loss for the same period.
- Click Calculate to find the RSI value.
Example
If the average gain over 14 days is 1.2 and the average loss is 0.8:
- RS = 1.2 / 0.8 = 1.5
- RSI = 100 − (100 / (1 + 1.5)) = 100 − (100 / 2.5) = 100 − 40 = 60
An RSI of 60 indicates moderate bullish momentum.
