We cannot get our complex, live, real-money EAs back-testing properly (i.e. achieve the same test results with 60x builds that we were getting with 509 and prior). They appear to trade properly (though it's not so easy to tell the detail), but back-testing shows very different results. There are so many different potential problems causing this, it's been impossible so far to work out which ones are the culprits and very difficult to fully eliminate anything from the list.
My post doesn't add any technical value I'm afraid but it does demonstrate that there are still capable people/teams out there struggling away with the new reality.
What size is your .fxt file ? if it's bigger than 4GB then that is the cause.
Yes it is, yesterday +5GB, thanks thats a good tip, findinf solutions.
How I can avoid make so big .fxt file, just using 1 min and period what running backtest like 1 Hour ?
or I can try to search from forum.

It makes no difference what timeframe you use, M1 will still be used, if available, to make the .fxt file . . . if you want a smaller .fxt file use a smaller date range. It's not what you want to hear I know . . . any real solution is in the hands of MetaQuotes . . . . but they are not upgrading MT4 so don't hold your breath.
Thanks for your reply, I just read several threads, where you have been writing fxt >4GB issue. they should make limit even smaller, people had to do walk forward, without notice :)
I dont know if britt tick datasuite will help.
off topic, sorry.
found also your interesting chart of ticks and brokers,

not big surprise fxcm was so different than others, they have fined for manipulating price running stops, virtual broker etc.....
and experience with gomarkets and heard from others traders, they dont play lot of tricks. i was using and 4x sentinel with forex4you broker and tick volume was incredible crazy, nosense,
Broker discussion is not allowed on this Forum, sorry.
I think the 4GB limit on .fxt is it, it used to be 2GB . . .

when it doesn't do what it should is it my code in error or a bug in mql4.5 that I am not aware of ? so yes, I'm in the same boat as you . . . it's really not a good situation . . . I can't test every single mql4 function I use, thats just not practical.
Absolutely, on every point. Raptor, if you're struggling/uncertain using the new build then we're all in the mire. At least we're not alone.

OK I added an init() to deinit() elapsed time calculation.
