I am writing this code in order to read the history of a symbol and save it in a dynamic array, but it returns (copied = -1), which means it cannot read anything. What is wrong with it?

Probably between these dates too much information for the selected period.
Try to choose another period or change interval of the dates.
I tried on this interval of the dates with a period in 15M.

Since a few days ago I'm having the same problem (previously my code was working fine). I think there is an issue here. I tried the posted code with a 15M period and it doesn't work.
Data is present in the directory Bases\MetaQuotes-Demo\history\ and I am using the same corresponding account.
Any help would be greatly appreciated.
