I built parts of it (caused my own intraday halt bug once). The place is run like a finance company rather than a technical one — they do tons of QA and they move glacially slow on tech adoption so lots of systems are way behind the curve compared to your modern tech company. Processes, technologies, methodologies are largely mandated from the top down by executives. You’re prohibited from trading and you don’t make the same amount of money you’d get at brokerages or hedge funds so they’re not really attracting quant level HFT engineers either. They do DR testing on weekends when the exchange is closed, they likely just forgot some operational process to revert for opening. The technical operations team was my biggest complaint - engineers aren’t allow to deploy their own software, there’s a special team that does it but they were practically incapable of doing anything on their own. I’d spend hours of my weekend watching a screen share of a guy trying to upgrade my package versions on our server for a deployment. He had a run book we had to write and me on the phone and he’d still fuck it up. I wanted him to cat a file or view the process list and I’d have to verbally spell out the keystrokes.
