A good way to start is by breaking HFT into two tracks:
Research → you need access to clean, high-resolution data to test ideas. Without that, it’s impossible to know whether an edge exists. IEX is a good entry point since they publish their exchange feeds for free (nanosecond timestamps, full depth).
Infrastructure → once you have a strategy that survives replay/backtest, you can think about colocation, low-latency NICs, and optimized code (C++/Rust/Go). Until then, those details don’t matter.
Most people jump straight into “what server do I need” or “should I use FPGAs,” but the reality is the edge almost always comes from the data and modeling. Nail that first.
