My layman's take on this: If you really do think you can make money at this, you'd be silly to waste your time mucking about with a retail options platform. Go get a job as a trader instead.

You'll have to go through quite a bit of training and apprenticeship and suchlike first. That's a good thing. It will get you access to higher quality information than is available as an outsider (those in the know don't dilute the earning power of their best knowledge by just giving it away). Possibly even better yet, you'll be getting paid to learn it instead of expending your own resources and free time.

Once that's done and you're set loose as a full-fledged professional trader, you'll quickly have a pretty enormous amount of capital to work with. You'll only get to take home a small cut of what you're able to earn with that money, but the total size of that cut is still going to dwarf what you can make just playing with your own money.
