Hello, I am testing a strategy which use only H4 chart, the tick on open only.
however, my code always download ticks data, it takes so a long time when i want to test it from 2005 to 2010.
Is there any way to get it faster (so i dont need to download all the tick data)?

thanks

        Calendar fromdate = new GregorianCalendar();
        Calendar todate = new GregorianCalendar();
        fromdate.set(2010, 07, 01);
        todate.set(2010, 11, 31);
        client.setDataInterval(Period.FOUR_HOURS, OfferSide.BID, ITesterClient.InterpolationMethod.OPEN_TICK, fromdate.getTimeInMillis(), todate.getTimeInMillis());
        client.setSubscribedInstruments(instruments);
        //setting initial deposit
        client.setInitialDeposit(Instrument.EURUSD.getSecondaryCurrency(), 5000);
        //load data
        LOGGER.info("Downloading data");
        
        Future<?> future = client.downloadData(null);
        
        //wait for downloading to complete
        future.get();

data get saved on your local machine, so you avoid dowload just by commenting out the correspoding lines, that is:

//Future<?> future = client.downloadData(null);
//wait for downloading to complete
//future.get();

Where is it saved?
According to the JAVADOC for downloadData() it downloads into the local cache. Is it possible to save it to the file and then read from it?
