Hi:

I want to use VOLUMEWAP indicator but when running the application it throws


12:09:31 Strategy tester: java.lang.ArrayIndexOutOfBoundsException: 1 @ jforex.RizHed_VWAP.isBuySignal(RizHed_VWAP.java:413)

The code compiles and is:

Object[] VWAP = indicators.calculateIndicator(instrument,
Period.DAILY,
new OfferSide[] {OfferSide.BID},
"VOLUMEWAP",
new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE},
new Object[]{0},
0);


Basically I just want to use the the price calculated VWAP but I dont seem to get around the interface.

Any help appreciated.

Thank you

Hi,
Two things: you have to set the offer side of the second input and change the value of the optional parameter (the minimum value of time period in VOLUMEWAP indicator is 2).
Object[] VWAP = indicators.calculateIndicator(instrument, Period.DAILY, 
        new OfferSide[] {OfferSide.BID, OfferSide.BID},"VOLUMEWAP", 
        new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE, IIndicators.AppliedPrice.CLOSE}, new Object[]{2}, 0);
