s
An financial series where the first element is the closing price in the last trading period, the second term is the closing price in the previous trading period and so on.
noOfPeriods
An integer which represents the number of previous time periods used over which the closing price is compared.
Evaluation of the Fast

#### Indicator variables

The Stochastic K depends on the following variable:

• Periods - the number of previous time periods used over which the closing price is compared.

Now the formulae for the Stochastic %K over a is:

100 x (Last Close - Lowest low)/(Highest high - Lowest low)

where the "lowest low" (respec. "highest high") is the highest (respec. lowest) close of the asset over the period under consideration. Since the "Last close", will lie between the highest high and lowest low this indicator will lie between 0 and 100.

# Syntax

#### Parameters

s
An financial series where the first element is the closing price in the last trading period, the second term is the closing price in the previous trading period and so on.
noOfPeriods
An integer which represents the number of previous time periods used over which the closing price is compared.

#### Return Value

A series where the first term is the KFastStochastic calculated for the most recent period, the second term is the KFastStochastic calculated for the previous period and so on.
