It's possible to buy a colo at an exchange for $$$ and push to prod from the house. Algorithmic trading is...algorithmic. trade decisions are encoded into the algorithm, decisions based on market feed info such as last executed orders, volume, etc. The idea is you take a previous trading intraday execution data set, profile out volume per second, execution prices, etc. Then encode a proprietary datascience backed decision tree for dispatching buy sell messages. No human in theol loop.
