Hi,

according to javadoc the stoch method should return shift+1 values in the returned array

double[] stoch(Instrument instrument,
               Period period,
               OfferSide side,
               int fastKPeriod,
               int slowKPeriod,
               IIndicators.MaType slowKMaType,
               int slowDPeriod,
               IIndicators.MaType slowDMaType,
               int shift)
               throws JFException

using this line of code

            double[] stochastic = indicators.stoch(instrument, fixedPeriod, side, fastKPeriod, slowKPeriod , slowKMaType, 
                    slowDPeriod, slowDMaType,  5);

the double array is getting only 2 positions created. a reference to stochastic[2] or stochastic[3] is raising an exception.

tested on EUR/USD, 15 mins with

    private OfferSide side = OfferSide.BID;
    private int fastKPeriod = 5;
    private MaType slowDMaType =  MaType.SMA;
    private int slowKPeriod = 3;
    private MaType slowKMaType =  MaType.SMA;
    private int slowDPeriod = 3;

please check or correct me if i am wrong.

many thanks

If you calculate the values by shift, you get values for a single candle only - in this case each array element stands for an output - and as you see stoch has two outputs.
If you wish to retrieve a value array for each of the outputs over a candle interval, use the following method:
