Right now, you can't trade equities, bonds, FX - and unless you can trade these core asset classes, your platform has to be classified "toy" - crypto-currencies just aren't that important, or not yet.
Personally, I tried out your platform because you said you have "trusted news"; but you don't cover agency news, only untrusted Web sites (probably via un-cached RSS-feeds, so quite slow) - no need to pull the graphical logos for each site, that's not what traders want I would argue.
Whatever you are building has to be better at something than the existing vendors (UI responsiveness, trading execution, price, feature richness, news sources, ...) to survive. Think hard about your USP!
It's hard to break into this (semi-oligopoly) space, as incumbents have spent decades innovating and/or acquiring and integrating data and functionality, but many would welcome a bit of fresh air.
