Method Detail

onStart

@Deprecated
public void onStart(IIndicatorContext context)

Deprecated.

Description copied from interface: IIndicator

Called on indicator initialization

Specified by:

onStart in interface IIndicator

Parameters:

context - allows access to system functionality

calculate

@Deprecated
public IndicatorResult calculate(int startIndex,
                                             int endIndex)

Deprecated.

Description copied from interface: IIndicator

Calculates values of the indicator from startIndex to endIndex of input parameter and places them in output parameters

Specified by:

calculate in interface IIndicator

Parameters:

startIndex - index of the first element in input parameters that needs corresponding indicator value. That doesn't mean that values before startIndex will not be read, they will be if lookback is more than 0. That also doesn't mean that value for startIndex will be calculated, it will be not if startIndex < lookback. IndicatorResult.getFirstValueIndex() returns index of the first element that has corresponding calculated value in output array(s)

endIndex - index of the last element in input parameters that needs corresponding indicator value

Returns:

object with first index in input that has calculated value and number of values calculated

getIndicatorInfo

@Deprecated

Returns:

object that describes indicator

getInputParameterInfo

object that describes input

getOptInputParameterInfo

index - index of the parameter

array - array of the doubles, ints or prices represented as double[][]

setOptInputParameter

@Deprecated

                                             java.lang.Object value)

Deprecated.

Description copied from interface: IIndicator

Sets optional input parameter. If one of the parameters not set, then default value should be used

Specified by:

setOptInputParameter in interface IIndicator

Parameters:

index - index of the parameter

value - int or double value

setOutputParameter

@Deprecated
public void setOutputParameter(int index,
                                           java.lang.Object array)

Deprecated.

Description copied from interface: IIndicator

Sets output parameter. Size of the array should be enough to hold calculated values requested with IIndicator.calculate(int, int) call

Specified by:

setOutputParameter in interface IIndicator

Parameters:

index - index of the parameter

array - array of doubles or ints enough to hold values from startIndex to endIndex

getLookback

@Deprecated
public int getLookback()

Deprecated.

Description copied from interface: IIndicator

Returns number of elements needed to calculate value of the first element. Usually depends on optional parameters

Specified by:

getLookback in interface IIndicator

Returns:

number of elements needed to calculate value of the first element

getLookforward

@Deprecated
public int getLookforward()

Deprecated.

Description copied from interface: IIndicator
