Stochastic Oscillator

The Stochastic Oscillator is a popular indicator that shows where a security’s price has closed in proportion to its closing price range over a specified period of time.

The Stochastic Oscillator has two components: %K and %D. %K is most often displayed as a solid line and %D is often shown as a dotted line. The most widely used method for interpreting the Stochastic Oscillator is to buy when either component rises above 80 or sell when either component falls below 20. Another way to interpret the Stochastic Oscillator is to buy when %K rises above %D, and conversely, sell when %K falls below %D.

KPeriods, KSlowingPeriods, and DPeriods are integers specifying the values used in the calculations. 
The most commonly used arguments are 9 for %K periods, 3 for %K slowing periods and 3 for %D smoothing. MAType is an integer specifying the moving average type to be used (Simple = 1, Exponential = 2, TimeSeries = 3, Variable = 4, Triangular = 5, Weighted = 6, VIDYA = 7)
