The possibility to select several symbols and perform an action on all of them.
For instance, you could select all the major currency pairs available at Dukascopy, right click and bring the symbol operations menu, then proceed to select a date range and click the Start download button which would queue a download for each of the selected symbols.
This would make it easier to keep an up-to-date tick data database. Bear in mind that command line options that allow bulk downloading are already available - you can simply create a batch file that refreshes all the symbols you care about.
Among other factors, planned features will be scheduled for implementation based on user preference. Press Yes below next to "Did you find it helpful?" if you'd like this feature to be prioritized for implementation. Feel free to press No if it's not a priority for you.
