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.
