Stochastic Oscillator
A momentum indicator showing where the close sits within the recent high-low range.
Also called: stochastics · stoch
In plain language
The stochastic asks a simple question: is price closing near the top or the bottom of its recent range? A reading of 80 means the close is 80% of the way up that range.
It is plotted as two lines — a fast line and a smoothed signal line — and, like RSI, is scaled from 0 to 100 with conventional overbought and oversold zones.
It reacts faster than RSI, which makes it more responsive and considerably noisier.
Why it matters
In range-bound conditions the stochastic can help time entries near the edges. In trends it produces a steady stream of premature counter-trend signals.
Common mistakes
- Using it as a reversal trigger in a strongly trending market.
- Trading every crossover without reference to structure.
