Stoch

Stochastic Oscillator

A bounded 0–100 oscillator that measures where the close sits relative to the high-low range over a chosen lookback — paired with a smoothed signal line for crossover triggers.

Developed by George Lane in the 1950s, the Stochastic Oscillator compares the current close to the trading range of the past N bars (typically 14). The fast %K line ranges 0–100, and a smoothed %D line (default 3-period SMA of %K) acts as a trigger. Readings above 80 are conventionally "overbought," below 20 "oversold."

Stochastic shines in ranging markets where price oscillates between support and resistance — the %K/%D crossovers in oversold/overbought zones produce reliable mean-reversion signals. In strong trends it tends to lock in extremes for long stretches, so use a trend filter alongside it.
