This strikes me as an odd post. You seem to say that algos cut into profit margins, and then suggest the answer to this is programming your own or aspiring to being an automaton. But in reality, the HFT firms are not (in aggregate) outperforming simply holding the assets they trade frequently (remember Buffett's very he just formally won, but was long ago conceded?)
Trading against algos means you're trading against the instructions someone gave to a computer previously...computers that can't say, "ok, I've hit my very precise threshold, but something looks different this time..." You're also not up against emotion (which I'm not suggesting is necessarily beneficial...I have little doubt there are profitable traders who looked for signs of panic or ecstasy), just hard rational logic. You're still watching human behavior, just a few degrees separated from the pit traders (the move from pits to screens being the first, and screens to programs being the second). You can still figure out people's intent, you just don't have the same clues. What once was screaming, sweaty, red faced, wide eyed pit traders in a panic to offload their shares became big red bars on charts. Now the goal is to figure out not when the panic sets in, but when the cold, rational, afterthought says, "ok, now it's time panic." Incidentally, this rational approach to the market exposes an opportunity to predict market activity because it's already been programmed. Doing so successfully is debatable, that it can be done is not.
To answer the OP, it depends on your experience and financial situation. If you've scraped together $10k working retail, at 31 trading probably isn't a natural move. If you've carefully built your nest-egg and have enough money to experiment in the market while your nest-egg stagnates for a few years, you might be able to work something out, especially if you have a financial background. Start buy leveraging your own knowledge to find what of your experience will translate well to the market, that will give you a good starting point to grow your trading knowledge.
