The short answer

The Stochastic Oscillator (Stoch) is a momentum indicator rated intermediate. Applied to USD/ZAR (exotic pair, 40-pip spread, 1200-pip daily range), the default settings are %K period: 14. %D period: 3. Overbought: 80. Oversold: 20. Best timeframes: M15, H1, H4. Key signals: Buy when %K crosses above %D below 20 (oversold cross). Sell when %K crosses below %D above 80 (overbought cross). Divergence with price is a reversal signal.

What Is the Stochastic Oscillator?

Compares a closing price to its price range over a given period. Like RSI, it oscillates between 0 and 100, with overbought and oversold zones. %K line = (Current close − Lowest low) / (Highest high − Lowest low) × 100 over N periods. %D line = 3-period SMA of %K. Above 80 = overbought, below 20 = oversold. The crossover of %K and %D generates signals.
