I was talking about the Oanda data downloaded by Zorro that are UTC and not GMT. I did not know Darwinex I will take a look. You should look at BarZone it usually does the job. If BarZone is not set you will get UTC data aligned (BarZone=24 by default) and if set to 0 you will get GMT. You can make sure of that by writing daily data to a csv with BarPeriod=1440, you will set BarZone=0 will get a daily closing time of 00:00 when GMT and UTC are aligned and 23:00 when daylight saving time is applied as GMT is then one hour ahead of UTC. So for GMT+2 you should be setting BarZone=2. To be honest, to my mind the EOD alignment making most sense is US-Eastern, as you will then have the week ending on Friday at 17:00 EST and starting on Sunday at 17:00 EST. The Sunday bar will then be a complete 24 hours bar as ending on Monday at 17:00 EST. It's a question of point of view but for having worked quite a long time on the financial markets I tend to choose this daily alignment.
