I've SQ Tick downloader version 64 bit, 4.6.0. When I try to download for example EURUSD, even only few days, in the autoscroll it appears the following: "Unable to download file http://dukascopy,com/datafeed/EURUSD/2018/00/01/00h_ticks.bi5 for many times. Why? What can I do?
The recent version of Tick Downloader on official website is 4.4.0, try installing it, hope it solves the issue.
