Re: Historical Forex Data Service
So M5 is in accordance with M15. The same must be done for M1 to see where it's going wrong. But I doubt there's an actual data error.
As far as I understand, all TFs are based on one and only dataset (M1) and all higher sets are built from it. Which makes perfect sense. Adding to this, there shouldn't be data errors because of this, but with MT anything goes unfortunately. I saw a list of steps how to update data files, which might help to avoid this error, I'll try to find it.
