Hi,
1. This workaround will work only on existing .fxt files in …testerhistory. So I use Tickstory to create fxt files to all desired pairs and time frames – the period is not important; it is only important that the .fxt files will exist in the …testerhistory folder. For me all of these .fxt files where not marked as read only as mentioned in this thread.
2. Launch Tickstory as administrator using right click on the desktop icon or changing the desktop shortcut advanced properties to allow it to run as administrator.
3. Repeat step 1 but now use the desired backtesting period (i.e. one year of data). This time, when the process ends, the .fxt files (which where there but was not marked as read only) will be recreated and marked as read only as desired.
Hope it helps
