Fisher Transform

Description

With distinct turning points and a rapid response time, the Fisher Transform uses the assumption that while prices do not have a normal or Gaussian probability density function (that familiar bell-shaped curve), you can create a nearly Gaussian probability density function by normalizing price (or an indicator such as RSI) and applying the Fisher Transform. Use the resulting peak swings to clearly identify price reversals.

Syntax

FisherTransform(int period)

FisherTransform(ISeries\<double\> input, int period)

Returns default value

FisherTransform(int period)[int barsAgo]

FisherTransform(ISeries\<double\> input, int period)[int barsAgo]

Return Value

double; Accessing this method via an index value [int barsAgo] returns the indicator value of the referenced bar.

Parameters

Parameter	Description
input	Indicator source data (Series<T>)
period	Number of bars used in the calculation

Examples

1 // Prints the current value of a 10 period using default (median) price type
2 double value = FisherTransform(10)[0];
3 Print("The current Fisher Transform value is " + value.ToString());
