It is currently 6:45PM EST and I am attempting to test against the demo server.
Keep seeing:
om.dukascopy.api.JFException: Instrument [EUR/USD] not opened
in my logs. Can someone point me to any information on the availability of the demo server and when rates are 'open' ?
thanks much,
Bob

Hello
I'm trying to familiarize myself with JForex Strategy API, and when I start the strategy there is a error that I can't understand.
I placed a small piece of code at the "onStart()" method in order to get the time of current bar. However, when I run the strategy the exception "Instrument [EUR/USD] not opened @ jforex...." is raised.
Then, just for a test, I changed place of that piece of code, placing it at the "onBar()" method. In that case it worked fine.
Why do this ocurr ?

A similar bug...
Please Support, check the method "getBar(Instrument instrument,Period period,OfferSide side,int shift) throws JFException"
It throws an exception when it is called in the "Strategy.onStart" method, as you can see -->> "com.dukascopy.api.JFException: Instrument [EUR/USD] not opened @ jforex.Strategy1.onStart"
However, the method above (getBar) works perfectly when I place it in the "Strategy.onBar(...) " method.
Thanks in advance.

Will be fixed in next version. Workarond for current version would be calling History.getTimeOfLastTick in cycle in onStart method untill it returns correct value ignoring exception it throws.
