What RSI actually measures
  • RSI is a momentum oscillator that compares the speed of recent gains to the speed of recent losses.
  • It does not mean that price must reverse simply because RSI is high or low.
  • Its real value comes from reading momentum in context, especially relative to trend structure.
Why overbought and oversold are misunderstood
  • In strong uptrends, RSI can remain elevated for long periods while price keeps trending higher.
  • In strong downtrends, RSI can stay weak without producing an immediate reversal.
  • For this reason, traders should treat RSI as a context tool rather than a stand-alone reversal signal.
RSI behavior in different regimes
  • Uptrends often show RSI finding support in higher ranges during pullbacks.
  • Downtrends often show RSI failing in lower ranges during rebounds.
  • Ranges produce more traditional oscillation behavior, where RSI swings between stronger and weaker zones.
Divergence
  • Bullish divergence appears when price makes a lower low but RSI forms a higher low, suggesting downside momentum may be weakening.
  • Bearish divergence appears when price makes a higher high but RSI forms a lower high, suggesting upside momentum may be weakening.
  • Divergence is a warning signal, not a complete trade setup. Structure and levels still need confirmation.
Checklist
  • What market regime is the chart in?
  • Is RSI behaving in a trend range or a range-bound oscillation?
  • Is there divergence at a meaningful price level?
  • What confirms the idea beyond RSI?
