Tester: Testing Features and Limits in MetaTrader 4

 
Zero bar of another timeframe for the same symbol under test is modeled approximately
Open = correct Open, Close = correct Close, Low = min (Open,Close), High = max (Open,Close), Volume = final Volume (false)
Is no longer correct, per Tester in the Terminal MetaTrader 4: It Should Be Known - MQL4 Articles and in EA testing
 

With Build 610 my strategy tester does not do any trade any more.

The EA is approved from Build 5xx and working in live accounts. New directory structure is understood. Many EAs and FX pairs were tried.

The strategy tester worked well before Build 610, now it says -Expert loaded, -Spread set, -Parameters set but NO trade is done during simulation. I can not get any output, even print statements fail.

I am helpless searching since 1 week, who can help?

Thanks, RoMe
