We do not, however, someone here mentioned awhile back that there is a pretty decent API available (I wish I remembered the name) that handles Metastock data nicely (as it is a proprietary format). I seem to remember that the API was relatively inexpensive (less than $500). We've got our hands full until at least September with the next edition, so if you need it anytime soon, that might be a good route to go.
Does RE have an out of the box way to read Meta Stock Data? If not would it be a big ask to add it?
I am not too sure of their file format.
