trade.invision.indicators.indicators.convergencedivergence.SimpleConvergenceDivergence

public class SimpleConvergenceDivergence
extends Indicator<Boolean>

SimpleConvergenceDivergence is a Boolean Indicator to test whether two Num Indicators converge or diverge over a length of values. "Simple" convergence-divergence uses a basic evaluation technique that tests if the percentage of values in a timeframe that align with the given convergence-divergence type are above a given threshold. This requires less computational power than "complex" convergence-divergence. Internally, this uses the LocalRisingPercentage and LocalFallingPercentage Indicators.

Method Details

simpleConvergenceDivergence

public static SimpleConvergenceDivergence simpleConvergenceDivergence(Indicator<Num> first,
 Indicator<Num> second,
 ConvergenceDivergenceType type,
 int length,
 Num percentageThreshold)

Gets a SimpleConvergenceDivergence.

Parameters:

first - the first Indicator

second - the second Indicator

type - the ConvergenceDivergenceType

length - the number of values to look back at

percentageThreshold - the percentage threshold. The percentage is represented as a fractional. For example, a provided value of 0.15 would represent 15%. Must be between zero and one.

calculate

protected Boolean calculate(long index)

Description copied from class: Indicator

Specified by:

calculate in class Indicator<Boolean>

Parameters:

index - the index

Returns:

the result (never null)
