I solved the problem. I just took the very super Dukascopy data history delivered by Popov and it is working amazing.

Only thing, which catches my eye, is naming. Do you use the correct naming format? In this example it must be EURUSD60.csv

I'm trying since 2 days to import HST to CSV but Forexsb refuse to load the CSV results and I don't know what is wrong.
My CSV result is like this:
2020-04-02    17:00    1,08513    1,09001    1,08438    1,08624    309                   (in one line)   

the CSV from FSB Demo Data is like this:
13/03/08    02:00    1.55220    1.55560    1.55220    1.55380    4              (in one line)

My CSV is not readable, the one from FSB Demo of course it is...

on the https://forexsb.com/wiki/fsb/manual/data_files is writted this:

"
The data in the text files is stored in rows and columns:
2008-05-19   19:00   1.5445   1.5456   1.5445   1.5451   43

The columns are as follows:

Date (2008-05-19 or 19.05.2008 or 05/19/2008);
Hour (19:15 or 19:15:00);
Open Price (1.5452 or 1,5452)
High Price
Low Price
Close Price
Tick Volume
"

If I compare the CSVs with the text from manual, my CSV is the correct one and the other one ( Demo Data) is not correct.

Where is the error? Why are not working my CSVs?

thanks
