stratgegy testing / optimization within current day

 

Hello,

 Is there a way to launch strategy tester or optimization against current unfinished day data ? Example : from midnight to now().

 When I choose date of today (before the end of the day) I have an errot message saying to go to math calculation mode (but I do not want to play with math I just want to run against last 10 hours for example).

 This would point to a near real time optimization process. Does anything like this in MT5. 

 Thanks for your help.
