What is Overbought / oversold?

Descriptions of a one-sided move (RSI above 70 or below 30), not predictions of a reversal.

Overbought means buying has dominated recently. It does not mean 'about to fall' — strong markets stay overbought for long stretches.

The useful version of the idea is context: an overbought pullback inside an uptrend behaves very differently from one inside a downtrend.
