- RS = average gain of up candles ÷ average loss of down candles over 14 candles (Wilder smoothing)
Default settings
Period 14, levels 70 and 30, midline 50
Settings by trading style
| Style | Setting | Note |
|---|---|---|
| Scalping | 5 to 9 with levels 80/20 | Fast, with more false signals |
| Daily | 9 to 14 with levels 70/30 | A balance of speed and accuracy |
| Swing | 14 to 21 with levels 70/30 | Calmer, suits the daily timeframe |
Main signals
- Moving back above 30 from the oversold zone
- Moving back below 70 from the overbought zone
- Crossing the 50 line to confirm direction
- Divergence: a higher price high with a lower RSI high
Common mistakes
- Selling just because RSI is above 70; in a strong trend RSI stays high for a long time
- Ignoring the trend direction on a higher timeframe
- Changing the period until the past chart looks «perfect»
