Technical & Chart Analysis
Overbought
A condition in which an oscillator sits at a high extreme after a rapid advance, indicating stretched momentum rather than a sell signal.
What Overbought means
Overbought is a reading, not a verdict. Bounded oscillators such as RSI, the Stochastic and Williams %R are scaled between fixed limits, and conventional thresholds place the overbought zone above 70 on RSI or above 80 on the Stochastic. When price rises quickly relative to its own recent range, the oscillator is pushed toward that ceiling. The condition simply says the recent advance has been fast and one-sided compared with the lookback window the indicator uses, which is typically fourteen periods on a default setting.
Traders use overbought readings mainly for context: to avoid chasing an extended move, to tighten a trailing stop, or to look for a mean-reversion entry when price is also failing at resistance. The honest limitation is that strong trends stay overbought for long stretches, and selling purely because an oscillator crossed a line is one of the most common ways beginners fight a trend. Most experienced users wait for a second signal, such as bearish divergence or a break of a short-term trendline, before acting.
Worked example
If EUR/USD rallies from 1.0750 to 1.0920 in four sessions, the daily 14-period RSI might print 76. That is overbought by the usual convention, yet the pair could still grind to 1.0980 before any pullback begins.
