Hello, I am new to JForex coding,
I hgave a problem, when i call indicator data it takes long time and throw exception..
Should i do something before using indicators or use indicators i a different usage?
Thanks much

Calling the indicator as like this

    try {
              ema_value = indicators.ema(instr, ema_period, OfferSide.BID, IIndicators.AppliedPrice.MEDIAN_PRICE, 14, 1);
        } catch (JFException ex) {
              Logger.getLogger(Trader_EURJPY_Long1.class.getName()).log(Level.SEVERE, null, ex);
        }

        try {
            natr_value_short = indicators.natr(instr, natr_short_period, OfferSide.BID, 14, 1);
        } catch (JFException ex) {
            Logger.getLogger(Trader_EURJPY_Long1.class.getName()).log(Level.SEVERE, null, ex);
        }

        try {
            cci_value_short = indicators.cci(instr, cci_short_period, OfferSide.BID, 14, 1);
        } catch (JFException ex) {
            Logger.getLogger(Trader_EURJPY_Long1.class.getName()).log(Level.SEVERE, null, ex);
        }

where
public Period natr_short_period = Period.TEN_SECS;
public Period cci_short_period = Period.TEN_SECS;
public Period ema_period = Period.FIVE_MINS;

and instr = Instrument.EURUSD;

Exception is :

com.dukascopy.api.JFException: com.dukascopy.charts.data.datacache.DataCacheException: Failed to load in-progress candle data in timeout period

It appears as there has been a temporary data cache server problem. Does the problem persist?

There is a strange situation. When i log in from my real account
This problem does not appear. When i log in from Demo account problem
appears. What may be the problem?
Best regards

On which indicator do you get the exception? For more efficient assistance, could you please:

1. provide an example strategy which replicates the case,
2. provide a precise test case and JForex-API version,
3. provide warning or error messages from Messages tab or Java Console, if any. If you launch the strategy from standalone, then please provide both the launching program and the logs.
