Has anyone used machine learning to trade?
randomtask: I don't know much about stock markets, but I did a consulting gig for a large currency trading company a while back where I was doing a bit of work on their algorithmic trading platform. I learned that unless you are trading at least a million dollars a trade it's very unlikely that you will make money.The reason for this is that the large companies won't talk to you unless you're trading at those volumes since they charge pretty high transaction fees. The smaller companies that will talk to you all have accounts with the larger companies and make money by increasing the spread between the bid and ask price they receive from the large companies. The expected return on a trade is usually somewhere in the region of 1-10 pips (where a pip is one ten thousandth of a dollar), with 10 pips being a really good return and 3-4 being more realistic. The smaller companies usually increase the spread by up to 3 pips in each direction on the price they get from the larger company which swallows up your return.While millions of dollars per trade might sound like a lot the leverage in this market is also very high at 50-100 times meaning that with your 10k you could trade 500k-1M though on a sum that low you might get less leverage. However if you lose money on a trade you could eat substantially into your capital. So if your $1M trade goes against you by 10 pips you'd lose 1k.I'm not ruling out making money on that market, but I'd say it's very unlikely unless you have a lot more money to start with. I am not an expert in this area though. This is just what I learned from the small amount of time I spent working with the company.
