Hello,

Doing a simple call of a minMax indicator produces "05:04:31 Error in indicator: java.lang.NullPointerException @ com.dukascopy.indicators.ZigZagIndicator2.calculate(ZigZagIndicator2.java:100)"

The offending code is a simple call to another indicator as shown in your examples.

int shiftminmax = 1;                 
         try { 
            double[] minMax = indicators.minMax(Instrument.EURUSD, Period.ONE_MIN, OfferSide.BID, AppliedPrice.CLOSE, 5, shiftminmax);
            }
            catch (Exception e) {
            icontext.getConsole().getOut().println(e);           
            } 

Would like a response today if possible. thx!

IIndicators is not available from other indicators. Please use IIndicatorProvider as described here:

Ok, so if I'm using

private IBar[][] inputs = new IBar[1][];  // new code

instead of

private double[][][] inputs = new double[1][][];

How do I set the input line here?

ZZIndicator.setInputParameter(0, inputs[0][0].getClose());

This does not work and gives a runtime error.
