What Is RSI?
RSI is useful when it is read as a momentum context signal, not as a blind overbought-or-oversold button.
The Relative Strength Index is a momentum oscillator that measures the speed and magnitude of recent price changes on a 0 to 100 scale.
RSI matters because it helps you tell the difference between healthy momentum, weakening trend quality, and exhausted countertrend bounces. Used badly, it creates premature reversals. Used well, it improves context.
- In strong uptrends, overbought readings can signal strength rather than immediate reversal.
- Divergence matters more when price is already near a key structure level.
- RSI becomes stronger when paired with trend and support-resistance context.
- Read RSI with the trend before reading it against the trend.
- Check the timeframe so you do not mix intraday noise with swing setups.
- Use divergence as a prompt for deeper review, not as a trade by itself.
- Shorting every overbought print in a strong uptrend.
- Buying every oversold bounce without checking structure.
- Ignoring the fact that regime changes the indicator's meaning.

Common questions
2 answersDoes RSI above 70 always mean sell?
No. In strong trends, RSI above 70 can simply mean momentum is healthy. The surrounding structure decides whether the reading is actionable.
What is the best RSI setting?
The default 14-period setting is a strong baseline, but the right setting depends on timeframe and how quickly you want the indicator to react.
