Oversold
Oversold describes a market condition in which price has fallen unusually far or fast relative to its recent history, as measured by a momentum oscillator, suggesting selling pressure may be stretched and due for a pause or bounce. The conventional threshold is RSI below 30, or a stochastic reading below 20. Like overbought, the term measures the speed of the recent move, not whether the asset is fundamentally cheap.
For example, if Ethereum drops 25% in a week during a market-wide sell-off and its daily RSI falls to 22, it is oversold by the standard definition. A mean-reversion trader might start watching for a bounce setup — perhaps a bullish divergence or a strong reversal candle at support — before committing capital.
The critical misconception is that oversold means it is safe to buy; in genuine downtrends and crypto capitulation events, assets can remain oversold for extended periods while price keeps falling, and buying solely on a low oscillator reading is often described as catching a falling knife. Context matters: an oversold reading during a pullback in an established uptrend is a very different situation from one during a structural breakdown, which is why traders combine oversold signals with support levels, market structure, and volume before acting.
