If you are asking the answer is probably no.

It is a very capital intensive business.

You need a large amount of capital to get started (single millions? maybe up to 10 million?)

You have a high barrier to entry: colocation at exchanges (expensive), expensive data feeds, sophisticated event-processing software...etc

Then after you have all that you need the brokerage relationships.

Then you need to actually develop a successful algorithm - and your competitors have many years more experience than you.

...etc...etc

You get the point.

However, you could look at automated technical analysis / to supplement your own retail trading, but HFT is its own game.

There's the possibility of middle men who are supposed to make some of these obstacles easier to overcome: http://news.ycombinator.com/item?id=1560072

Are you speaking from personal experience by the way?
