HI
I have MQ4 EA,I wang to convert to JFOREX,but I don't know hou to call these indicators function.
10 yeasr ago,I wrote EA call these function as:
double m0=indicators.sma(insturment.EURUSD,Period.TEN_MIN,OfferSide.BID,IIndicators.AppliedPrice.MEDIAN_PRICE,period,0);
double m1=indicators.sma(insturment.EURUSD,Period.TEN_MIN,OfferSide.BID,IIndicators.AppliedPrice.MEDIAN_PRICE,period,1);

It's easy to change from MQ4 to JFOREX.
But I canot find these function ,I read the sample,it used as the follow(It's very difficut to undserstand):
Object[] indicatorResult = indicators.calculateIndicator(selectedInstrument, Period.TEN_MINS, new OfferSide[] {OfferSide.BID},
"SMA", new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE}, new Object[] {30}, 0);
double m0 = (Double) indicatorResult[0];
indicatorResult = indicators.calculateIndicator(selectedInstrument, Period.TEN_MINS, new OfferSide[] {OfferSide.BID},
"SMA", new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE}, new Object[] {30}, 1);
double m1 = (Double) indicatorResult[0];

Hello,

Your example is correct. There is two options for retrieving sma value: use standart indicators.calculateIndicator() method and specify indicator by name, or use already provided indicators.sma() method.

Code sample:

    public void onStart(IContext context) throws JFException {
        this.console = context.getConsole();
        this.history = context.getHistory();
        this.context = context;
        this.indicators = context.getIndicators();

        Instrument selectedInstrument = Instrument.EURUSD;
        int timePeriod = 30;

        //first option
        Object[] indicatorResult = indicators.calculateIndicator(selectedInstrument, Period.TEN_MINS, new OfferSide[] {OfferSide.BID},
                "SMA", new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE}, new Object[] {timePeriod}, 0);
        double example1FirstBar = (Double) indicatorResult[0];
        indicatorResult = indicators.calculateIndicator(selectedInstrument, Period.TEN_MINS, new OfferSide[] {OfferSide.BID},
                "SMA", new IIndicators.AppliedPrice[] {IIndicators.AppliedPrice.CLOSE}, new Object[] {timePeriod}, 1);
        double example1SecondBar = (Double) indicatorResult[0];

        //second option
        double example2FirstBar = indicators.sma(Instrument.EURUSD,Period.TEN_MINS,OfferSide.BID,IIndicators.AppliedPrice.MEDIAN_PRICE, timePeriod, 0);
        double example2SecondBar = indicators.sma(Instrument.EURUSD,Period.TEN_MINS,OfferSide.BID,IIndicators.AppliedPrice.MEDIAN_PRICE,timePeriod, 1);

        console.getOut().println(example1FirstBar);
        console.getOut().println(example1SecondBar);

        console.getOut().println(example2FirstBar);
        console.getOut().println(example2SecondBar);
    }
