Thanks for your swift reply, @Shivank.
As far as I know, my colleagues in the Operations team are working to offer stocks on MT4, too.
The reason why assets are split among different trading account groups is mainly the ability to create a DARWIN out of the systems.
If you were "just" interested in having a live trading account with all our assets, that's sth we could do. However, I am afraid it would not be possible to list a DARWIN out of such a strategy, the reason being that the risk manager behaves differently in case of fx or equities because of the different risks involved in each case.
We take note of the feedback, though, in an ideal world we should be able to offer all the assets under account.
