Hi tcferreira,
Thanks for your post. Yes, Tickstory does provide end-to-end functionality to allow users to create MT4 databases with quality tick data from Dukascopy and then launch MT4 to allow you to perform 99% back-tests. This said, the intention is not to specialise in MT4 as TDS does (and I believe it does it well).
There are many additional features planned to assist traders manage their data – Metatrader being just one of the many platforms Tickstory intends to support.
Regards.
