Hi

First, I'd strongly recommend installing the Java JForex client - it's much more convenient than the web interface as you can select date ranges, as well as a number of different bar types, date formats, file formats etc. It only takes a couple of minutes to register.

Second, I don't use time based bars or ticks so I haven't come across the issue with DST. I understood that the downloaded data is normalised to GMT. If there is an issue, Dukas usually get around to answering on the forum but they can be a bit slow. Usually if you post something in the bug section it gets a quicker reply.

Please report back with anything you find out...
