Ok thanks for your input, i am going to try a bit more later.

Another thing i am confused right now:

i try to import price data with the CSVtoHistory script, (with an older version i think it worked)

The point is the Data is formated like this (and it's a huge file (500mb+):

1986.12.01,01:00,0.90110,0.90110,0.90110,0.90110,4
1986.12.01,01:01,0.90110,0.90110,0.90110,0.90110,4
1986.12.01,01:02,0.90110,0.90110,0.90110,0.90110,4
1986.12.01,01:03,0.90110,0.90110,0.90110,0.90110,4

i am using this format code: string Format = "+%Y.%m.%d,%H:%M,f3,f1,f2,f4,f6";

To notice is that there are no seconds, since it's M1 data

if i start the parsing script i get an error:

Error 058: Bad date 01:01,1.43
(1.43 is the start of the first price for the file i tried in this example)

That look like dataparse wants to have the seconds for sure? How to solve this? to Edit the files is not very easy for me as well, if it would be smaller i could just change format of time in excel, but it's to big file, would need to split it into 10+ files The Point is, it must have worked like this in version 1.72.x if i remember right, but not anymore.
