@MatPed , if you have not used MT4 before, it sucks in many ways. Histories is just one of the flaws of MT4.
As someone already told you, Darwinex didn't exist in 2011.
But there's more to that: originally, Darwinex used UTC timezone for MT4. A few years ago, maybe in 2016, Darwinex changed its timezone for MT4, answering to a request of some users, in order to get 5 daily candles per week, and not 6, with one of them incomplete.
And another thing: With MT4, you are not downloading the full history from the broker you are connected to. The broker stores some of the histories, like -I'm not sure right now- 3 months, and the rest of the histories you request are downloaded from other servers... MetaQuotes, for instance.
The thing is: with MT4 you are can not be sure of the consistency and credibility of the histories. IF you are not using MT4, and you are using Zorro, then my suggestion is DON'T USE MT4 histories. Download them from other platforms, and download them in real time from Darwinex (storing histories in CSV for instance), and backtest with those other histories, and after you have stored sufficient histories from Darwinex "live" check if your expectations from your backtest match the results you are getting from Darwinex.
I don't know if this suggestions fit to your needs, or if other traders using Zorro do it this way or not... But this is my preferred mehod
