Stochastic Indicator Formula (Chart Controls)

The stochastic indicator formula calculates the simple stochastic indicator (%K) and the smoothed stochastic indicator (%D). %D is a moving average of %K. The output is a percentage. A value more than 80% indicates that the current price is close to the price high, and a value less than 20% indicates that the current price is close to the price low.

The stochastic indicator is an indicator of upward and downward market trends.

Formula Details

Syntax

Chart.DataManipulator.FinancialFormula(
    FinancialFormula.StochasticIndicator,
    "PeriodK,PeriodD",
    "High,Low,Close",
    "%K,%D")

Parameters

This formula takes two optional parameters.

• PeriodK
  Period for calculating %K. The default value is 10.

• PeriodD
  Period for calculating %D. The default value is 10.

Input Values

This formula takes three input Y values.

• High
  Daily high price.

• Low
  Daily low price.

• Close
  Daily close price.

Output Value

This formula outputs two Y values.

• %K
  Simple stochastic indicator. The default value is 10.

• %D
  Smoothed stochastic indicator. The default value is 10.

Remarks

The Line chart type is a convenient chart type to display the formula output.

Example

The following example takes input from Series1's Y values for the daily high, low, and close prices (Series1:Y,Series1:Y2,Series1:Y4), and outputs %K on Series3 (Series3:Y) and %D on Series4 (Series4:Y). It uses a period of 15 days to calculate both %K and %D.
