RSI measures the speed and change of price movements to determine if an asset is overbought or oversold. It’s like a thermometer for market enthusiasm. RSI ranges from 0 to 100; above 70 is overbought, below 30 is oversold. How is it used?
- Overbought/oversold: Sell when RSI > 70, buy when RSI < 30.
- Divergence: If price makes new highs but RSI doesn’t, a reversal may be coming.
- Trend confirmation: RSI above 50 supports bullish trends; below 50 supports bearish.
- Average Gain/Loss: Calculate the average gain and loss over a period (typically 14).
- Relative Strength (RS): Average Gain / Average Loss.
- RSI: 100 - (100 / (1 + RS)).
