Hello Dukascopy community!

I'm trying to code an indicator that'll calculate an overall currency strength of each currency of the current charts pair.
I.e. if you add it to a EURUSD chart, it will calculate an index / basket value for EUR and one for USD, if you add it to AUDGBP chart, one for AUD and one for GBP etc.

I do have experience in Java but am new to the JForex API.
I haven't found the way yet to access the current charts currencies (or even pair to then .substr() it), but I'm sure there has to be a way?!
Unfortunately the wiki and javadocs are not quite as helpful in this regard as I'd like them to be.

Any help would be much appreciated!

Turns out it does work via the FeedDescriptor:

IFeedDescriptor feed = context.getFeedDescriptor();

        if (feed != null)
        {
            Instrument instrument = feed.getInstrument();
            this.base = instrument.getPrimaryJFCurrency();
            this.counter = instrument.getSecondaryJFCurrency();
        }

Indicator can receive data from different instruments:

        inputParameterInfos = new InputParameterInfo[] { new InputParameterInfo("USD", InputParameterInfo.Type.DOUBLE) {
            {
                setInstrument(Instrument.EURUSD);
            }
        }, new InputParameterInfo("GBP", InputParameterInfo.Type.DOUBLE) {
            {
                setInstrument(Instrument.EURGBP);
            }
        }, new InputParameterInfo("AUD", InputParameterInfo.Type.DOUBLE) {
            {
                setInstrument(Instrument.EURAUD);
            }
        } };

This data would allow to compare relative strength of different currencies.
