Hi Support,
Not sure what happened but the supportResitance indicator now returns "NaN". There was no problem before and I didn't change my code. Here is the code I used.
public void onTick(Instrument instrument, ITick tick) throws JFException {
double[] SR = indicators.supportResistance(instrument.EURUSD, Period.ONE_MIN, OfferSide.BID, 0);
double currentRes = SR[0];
double currentSup = SR[1];
console.getOut().println(currentSup);
}
Thanks

Support and resistance indicator uses the fractal indicator in its calculations with the default value of 2 for the 'Number of bars on sides' parameter which is the value used for Fractal's lookforward.
Indicator will return Double.NaN when calculated for the in-progress bar as well as for the bar previous to the in-progress bar.
Consider the following: indicators.supportResistance(instrument.EURUSD, Period.ONE_MIN, OfferSide.BID, 2); Notice the value of shift parameter equals 2.
