Readings above 70 are often called "overbought" and below 30 "oversold," suggesting a move may be stretched. But RSI can stay overbought or oversold for a long time during a strong trend, so those labels are hints, not signals.
RSI is one input among many. On its own it does not tell you where price is going; it simply summarises recent momentum. Like every technical tool it describes the past and offers context, and is not financial advice.

RSI (Relative Strength Index) — questions fréquentes
Does a high RSI mean I should sell?
No. Overbought can persist through a strong uptrend, so RSI is context to weigh, not a trade instruction. This is not advice.
Is RSI enough to trade on?
No single indicator is. RSI works best alongside price structure and other evidence, never in isolation.
