Hi ,
Today 25.01.2015 Sunday , i have suffer with the same message in the historical tester.
I thing this is a bug who comes with Demo update.
I haved runnig demo from the last week , and when i tried to test a strategy , i found something weird - the system isn`t drawing horisontal lines at the stoploss prices , also not drawing horisontal lines for offers and bids. After exiting , and starting the demo again in the Java console i saw line containing "update = true", after that i wasn`t able to test any of my strategies.
in the historical tester start to apear the following message: "Cannot get the last tick for the EUR/USD"
I created simlple strategy from scratch, install latest java update , clear temp files (installed applications too) in the java control panel , clear the cache in the JForex - and get the same result!

the code:

package jforex;

double price = history.getLastTick(Instrument.EURUSD).getBid() - 50 * Instrument.EURUSD.getPipValue();
IOrder order = engine.submitOrder("order" + counter, Instrument.EURUSD, OrderCommand.PLACE_BID, 0.01,
price, 0, 0, 0, 0);
}
}
}

The Jave console registered the following:
