Stochastic Oscillator (STOCH)

The Stochastic Oscillator (Stoch) normalizes price as a percentage between 0 and 100. Normally two lines are plotted, the %K line and a moving average of the %K which is called %D. A slow stochastic can be created by initially smoothing the %K line with a moving average before it is displayed. The length of this smoothing is set in the Slow K Period. Without the initial smoothing ( i.e., setting the Slow K Period to a value of 1 ) the %K becomes the 'Raw %K' value, and is also known as a fast stochastic.

Configuration Options

  • Period: Number of bars to use in the calculations.
  • Field: Price or combination of prices to use as the base for average calculations. Possible values include:
    • Open
    • High
    • Low
    • Close
    • Adjusted Close
    • HL/2 \( \left ( \frac{High + Low}{2} \right ) \)
    • HLC/3 \( \left ( \frac{High + Low + Close}{3} \right ) \)
    • HLCC/4 \( \left ( \frac{High + Low + Close + Close}{4} \right ) \)
    • OHLC/4 \( \left ( \frac{Open + High + Low + Close}{4} \right ) \)
  • Smooth: Whether to smooth the curve.
  • Color Selectors: Colors to use for graph elements.
  • Over Zones Enabled: Whether to shade the area between the plot and the horizontal overbought and oversold levels.
  • Over Bought: Overbought quantity
  • Over Sold: Oversold quantity
  • Display Axis Label: Whether to display the most recent value on the Y axis.

Formula

Fast %K = 100 SMA ( ( ( Close - Low ) / ( High - Low ) ),Time Period )

Slow %K = SMA ( Fast %K, Kma )

Slow %D = SMA ( Slow %K, Dma )

Where:

  • Close = the current closing price
  • Low = the lowest low in the past n periods
  • High = the highest high in the past n periods
  • Kma = Period of Moving Average used to smooth the Fast %K Values
  • Dma = Period of Moving Average used to smooth the Slow %K Values
