Hi support,

Are javadocs for methods of interface IIndicators planned?

Hi,
Please have a look at the following JForex Wiki article: https://www.dukascopy.com/wiki/index.php ... _interface

I meant the interface IIndicators which defines all the methods for getting the values of standard indicators such as ema(...), ma(...) and so on.

Hi,
Have a look at the following:
https://www.dukascopy.com/client/javadoc ... ators.html
Also, have a look at the overview section of the following article: https://www.dukascopy.com/wiki/index.php ... Indicators

Thank you. Especially the second link was helpful.

But however the parameter timePeriod in method

double[] sma(Instrument instrument, Period period, OfferSide side, IIndicators.AppliedPrice appliedPrice, int timePeriod, long from, long to)

isn't clear for me

I constantly get
com.dukascopy.api.JFException: Interval from [2011.04.29 00:05:17 500] to [2011.04.29 00:05:37 500] GMT is not valid

And here is the method call
double[] result = indicators.sma(instrument, period, OfferSide.BID, IIndicators.AppliedPrice.MEDIAN_PRICE, 2,tick.getTime() - 20000, tick.getTime());

Hi,
long from is the start time of the first candle in the calculated period and long to is start time of the last candle in the calculated period
Try using the following code:

long from = history.getBar(Instrument.EURUSD, Period.ONE_HOUR, OfferSide.BID, 2).getTime();
long to = history.getBar(Instrument.EURUSD, Period.ONE_HOUR, OfferSide.BID, 1).getTime();
        
double[] result = indicators.sma(instrument, Period.ONE_HOUR, OfferSide.BID, IIndicators.AppliedPrice.MEDIAN_PRICE, 2, from, to);

At the moment I don't need this method but thanks for answer. I will try it out.
