Step-by-step procedure

See the procedure infobox above for the seven steps.

RSI formula

RSI = 100 - (100 / (1 + RS))

Where RS = average gain / average loss over the period.

Common pitfalls

  • Overbought ≠ sell: In strong uptrends, RSI can stay >70 for days.
  • Oversold ≠ buy: In strong downtrends, RSI can stay <30 for days.
  • Period sensitivity: 7-period RSI gives many false signals; 21-period misses fast moves.
