Hi Jack,
I am not aware of any “corrections” to the Dukascopy data. The change from the .bin to .bi5 format was to make use of the best compression and reduce data sizes/bandwidth usage. The tick data itself should be unchanged.
If for some reason you want to re-download the data from Dukascopy, you can delete the appropriate range of dates in your data store location and Tickstory will automatically back-fill the missing data.
For the sake of efficiency and bandwidth, Tickstory will not attempt to retrieve data from the remote servers if there is valid data that resides on your disk.
Regards.
