Oscillator that helps identify momentum extremes, overbought and oversold conditions, and possible divergence setups.

What it is

RSI (Relative Strength Index) is a momentum oscillator from 0 to 100.

RSI above ~70 is often called overbought; below ~30 is often oversold.

It measures speed/strength of recent moves — not “value.”

Lesson diagram 1
How to identify it

RSI near/above 70 can signal stretched upside momentum and often appears in overbought conditions.

RSI near/below 30 can signal stretched downside momentum and often appears in oversold conditions.

In strong trends, RSI can stay high or low for a long time.

What it means

Overbought doesn’t mean “must sell” — it can mean strong trend.

Oversold doesn’t mean “must buy” — it can mean strong downtrend.

RSI divergence can warn momentum is weakening and may sometimes appear before a reversal setup develops.

Lesson diagram 2
Common mistakes (avoid these)
  • Shorting just because RSI is above 70 in a strong uptrend.
  • Buying just because RSI is below 30 in a strong downtrend.
  • Using RSI alone without trend + levels.
Why it’s useful

Helps spot stretched momentum conditions.

Helps confirm trend strength (RSI tends to stay elevated in uptrends).

Helps identify overbought, oversold, and divergence conditions that traders often monitor closely.
