double[]

getMinMax(int outputIdx, Object values, int firstVisibleValueIndex, int lastVisibleValueIndex) This method will be called once for every output.

Method Detail

getMinMax

double[] getMinMax(int outputIdx,
                   Object values,
                   int firstVisibleValueIndex,
                   int lastVisibleValueIndex)

This method will be called once for every output. Method must return array of doubles with two elements - minimal and maximal value. This values will be used to define scale for the indicator if it's drawn on separate panel under main chart. If one of the elements is Double.NaN, then it will be ignored

Parameters:

outputIdx - index of the output parameter

values - array of the values (int[], double[] or Object[] depending of the type of the output)

firstVisibleValueIndex - index of the first value that corresponds to the candle that is visible on the screen. Will be 0 even if the values array is with the length of 0

lastVisibleValueIndex - index of the last value that corresponds to the candle that is visible on the screen. Will be -1 if the values array is with the length of 0

Returns:

returns array of doubles with minimal and maximal values. First element is minimal, second is maximal value
