Stochastic Oscillator

Momentum in Range

The Stochastic oscillator compares a closing price to its price range over a period. It shows where the current close is relative to the recent high-low range.

Reading Stochastic

%K: Main line (fast)
%D: Signal line (3-period SMA of %K)

Overbought: Above 80 (price near top of range)
Oversold: Below 20 (price near bottom of range)

Stochastic Signals

Crossovers in extremes:
- %K crosses above %D below 20 → Bullish
- %K crosses below %D above 80 → Bearish

Divergences:
- Same concept as RSI divergences

Stochastic works best in ranging markets. In strong trends, it can stay overbought/oversold for extended periods.

Key Takeaways

  • Shows where price closed relative to recent range
  • Above 80 = overbought, below 20 = oversold
  • Best used in ranging markets
  • Crossovers at extremes generate signals
