For weeks, using MT4 build 225, I've been running strategy tester ok against eurusd data from 2009.01.01 to the then present date.
I guess it got tired of the same routine, and this morning it decided to start on Oct 27, 2009 while 2009.01.01 is still set in the Tester Settings dialog.
When I set the date to 2009.12.01 it starts correctly on Dec 1, 2009, but with 2009.01.01 it goes back to the Oct 27, 2009 start date.
What broke? How can I fix it?
