Looks good, thank you!

Just one comment, the PR description says DJX index was added but it is not in the mhdb file. Also, no specific symbol properties required for any of these indices?

Added DJX, sorry missed out in the PR
I did not find a solid source for SPDB changes, I will create a new PR with changes in SPDB for all index together if I see a good resource.
