Typical Interpretation

  • Readings above roughly 70 are often described as overbought, suggesting upward momentum may be stretched
  • Readings below roughly 30 are often described as oversold, suggesting downward momentum may be stretched
  • Some traders also watch for divergence, where price makes a new high or low that RSI does not confirm
