Method Summary

Modifier and Type	Method	Description
boolean	isReady()	Ready when the moving average is: the distance has nothing to wait for but the average.
void	reset()	Returns the moving average it updates to its pre-first-update state, as a holder does.
double	update(double newValue)	Computes the fractional distance of the current price from its moving average: (price - MA) / MA.

Constructor Details

DistanceFromMaRTIndicator

public DistanceFromMaRTIndicator(@NonNull
 @NonNull RTIndicator maIndicator)

Method Details

isReady

public boolean isReady()

Ready when the moving average is: the distance has nothing to wait for but the average.

Returns:

true if the indicator has completed its warmup period

reset

public void reset()

Returns the moving average it updates to its pre-first-update state, as a holder does.

Specified by:

reset in interface Resettable

Overrides:

reset in class AbstractRTIndicator

update

public double update(double newValue)

Computes the fractional distance of the current price from its moving average: (price - MA) / MA. Returns 0 when the MA is zero to avoid division by zero. Positive values indicate price above the MA; negative values indicate below.

Specified by:

update in interface RTIndicator

Overrides:

update in class AbstractRTIndicator

Parameters:

newValue - the current price

Returns:

the fractional distance from the moving average
