It seems as if there's a lot of behind the scenes data aggregation and analytics, which is good. But surely somebody has created a cheap variation on the rest of it? I.e. software with keystrokes to quickly access open financial data? I mean there's nothing to stop someone doing that, getting custom keyboards made, and selling it for a tiny fraction of the price right?

I'd imagine that there are quite a lot of people who fancy trading as something of a hobby but who will never pay for Bloomberg.
