InputParameterInfo |
getInputParameterInfo(int index)
Returns object that describes one of the inputs
|
int |
getLookback()
Returns number of elements needed to calculate value of the first element.
|
int |
getLookforward()

|
OptInputParameterInfo |
getOptInputParameterInfo(int index)
Returns object that describes optional input
|
OutputParameterInfo |
getOutputParameterInfo(int index)
Returns object that describes output

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 valuepublic IndicatorInfo getIndicatorInfo()
