I was playing around on cash app and spent a few dollars on the stocks there. I got bored of it eventually, but it got me thinking that there has to bots for this already.
I want a bot that I can give a dollars worth of stock. If that dollar’s worth rises by two cents, I want it sell a cent, and put the other cent into a pool for the next dollars worth of stock.
This has to have been done before, I just never learned anything about it.
This is sort of how High Frequency Trading firms - they have a system of algorithms to quickly buy and sell shares for profit. But they can do it a financial scale which makes sense. Like another commenter said, doing it for pennies will just be a net loss after commission and fees.
You also need to get approval (forgive me I can’t recall the exact detail) for day trading - buying and selling of a stock within (I think) a 3 day period (or maybe intraday). Some platforms will allow you to do it a couple of times but then restrict you until a few days have passed before you can trade agaib
I picked up a high frequency trading server for free off a friend of mine and that machine is a total beast of a computer. So apparently it may take a lot of horsepower to perform at that level
There is a lot of analytics that happen with HFT also I would say there hardware would prioritise low latency parts to shave nanoseconds off any trade.
FPGA, gigantic in memory caches, and ten gig fiber back channel connections to the exchange server in the next rack over.
We are hopelessly outclassed.
Fun thing, in Australia in order to connect to the Australian Stock Exchange you must have a minimum of 160M of fibre cable. So being in the rack next to them is not an advantage.
When they can make millions extra a year, spending 500K on a server is nothing.
