Hello support,

I have this in my code:

IBar bar0=history.getBar(instrument, Period.ONE_MIN, OfferSide.BID, 0);
long a=bar0.getTime();
java.util.Date d=new java.util.Date(a);
console.getOut().println( instrument.toString()+" "+ d.toString());

After the Stritegy run normally for a while an error occur and the stategy is stoped:
here is the message:

08:15:25 com.dukascopy.api.JFException: "to" parameter can't be greater than time of the last formed bar for this instrument @ jforex.Strategy12.onTick(Strategy12.java:149)
I want to know how could this happen? and how to slove it?

I am sorry, I tried many times and finally I find the error comes from the code on calling indicators.
this error comes occasionally when it is running. and I got the message
"12:12:32 "to" parameter can't be greater than time of the last formed bar for this instrument"


public void onTick(Instrument instrument, ITick tick) throws JFException {
try{

IBar m15bar0=history.getBar(instrument, Period.THIRTY_MINS, OfferSide.BID, 0);
IBar m05bar0=history.getBar(instrument, Period.FIVE_MINS, OfferSide.BID, 0);
IBar m01bar0=history.getBar(instrument, Period.ONE_MIN, OfferSide.BID, 0);

double cci15=indicators.cci(instrument, Period.FIFTEEN_MINS, OfferSide.BID, 14, Filter.WEEKENDS, 1, m15bar0.getTime(), 0)[0];
double cci5=indicators.cci(instrument, Period.FIVE_MINS, OfferSide.BID, 14, Filter.WEEKENDS, 1, m05bar0.getTime(), 0)[0];
double cci1=indicators.cci(instrument, Period.ONE_MIN, OfferSide.BID, 14, Filter.WEEKENDS, 1, m01bar0.getTime(), 0)[0];
///.....
}
catch (Exception e) {
print(e.getMessage());
}

return;
}

is this a BUG of JForex? because there is no "to" parameter in the code.

if there is no Try ...Catch .. ,the stragegy will stop on this error.

Hi,
Does this problem persist?
We have tested the code posted above without try-catch and exception doesn't occurs.

Sure it persist. I am using the version JForex 2.6.23
the whole code is attached.

Please download the last jnlp file version from Dukascopy Bank site and try to run the test1 strategy posted above and reply stack trace if any exceptions occurs. We have tested this strategy for about 2 hours and everything seems to work fine.
