Hi,

I'm using this method on my strategy:

public double getValue(Instrument instrument) throws JFException
{
JFUtils utils = context.getUtils();
double pipvalue = utils.convertPipToCurrency(instrument, cuenta.getCurrency());
return pipvalue;
}
I call this method on every 10sec bar. When Internet connection is lost and connection comes back I get this error message:

17:58:16 com.dukascopy.api.JFException: Unable to make the conversion. There are no active, subscirbed instruments containing EUR.


I guess that it is because the instruments are temporally unavailable. I would like to avoid this error because the strategy is supposed to monitor the prices every 10 sec and make a kind of trailing stop. How can I avoid this happening?

Thanks

Consider handling the exception and returning the previous value in such case.
What in particular you want to avoid? If the connection is not there, you neither receive latest prices, nor can do trading operations.

I have no experience handling exceptions. Actually I have limited knowledge of java, I'm slowly learning it with the only purpose to code strategies.

Could you please tell me if this would work to avoid the strategy stopping?

This is the method which throws the exception:

public double getValue(Instrument instrument) throws JFException
{
JFUtils utils = context.getUtils();
double pipvalue = utils.convertPipToCurrency(instrument, cuenta.getCurrency());
return pipvalue;

}

I used to call getValue method with the statement:

pipvalue = getValue(instrument);

Would this work to handle the exception and avoid the strategy stopping?

try
{
pipvalue = getValue(instrument);
}
catch (JFException exc)
{
print("exception:" + exc);
return;
}

Thanks a lot for your help

The exception handling is fine.

As long as 'pipvalue' holding the value returned by getValue() holds its old value from a previous call to getValue(),
then when the exception occurs, you will catch it and 'pipvalue' will remain unchanged.

Thanks a lot for your help. I didn't see your answer till now since I was not looking at the forum.
