Hi tcferreira,
To use TDS, just install the product in the usual manner. When you launch from Tickstory, it will automatically detect the presence of the tds.exe file and run it if it is there.
The data exported from Tickstory is compatible with TDS, however only fixed spread exports are available from Tickstory for the moment. There is an item to add support for variable spreads in the future.
Regards.
