Hello,
First of all, i'm a beginner
Is it possible to use the following code, and if yes, how i must use it ?

 
...
import com.dukascopy.api.feed.*;

public class MyForexIndex implements IIndicator {
...
private IHistory history;
private IBar myBar;

...
public void onStart(IIndicatorContext context) {
       
      IHistory history=context.getHistory();
      myBar=history.getBar(Instrument.EURUSD, Period.ONE_HOUR, OfferSide.ASK, 5);
...

When i try to compile it, i have an unhandled exception type JFException...

Did i'm not using this function as it musr be used ?

By advance, thanks.

All of the methods in IStrategy (onBar, onStart, onTick, etc.) can throw JFException. Therefore you need to change your method to:

public void onStart(IIndicatorContext context) throws JFException {
        
      IHistory history=context.getHistory();
      myBar=history.getBar(Instrument.EURUSD, Period.ONE_HOUR, OfferSide.ASK, 5);
}

Thanks tommy5d.
However, when i try to compile it, an error occurs:



Ant idea ?

Thanks

What are you trying to do? Are you trying to make a strategy or an indicator?

I'm trying to make an indicator.

You need to handle the JFException, i.e. surround it with a try-catch block, as it is done in the following indicator (see lines 80 and 91):
