With Tickstory I don't have holes in Dukascopy data.
The feature that I think could be useful is to create an internal database that inform TickStory of still downloaded data.
When I ask to export data, Tickstory should contact Dukascopy server only to download last required data that are not present on hard disk.
Instead it takes a lot of time to require and (could be) check data that were downloaded months ago.
For example could it be possible to create a function to "validate" previously downloaded data.
Could it be also a simple request to the user like : "Accept as good previously downloaded data and request only new data".
Could it be a simple CheckBox.
This feature could quicker create exported data.
Also, I want to be able to choice the interface language.
It's impossible to translate all technical term in local languages and I prefer to read the English interface messages.
