I'm mind-blown by the tech that powers this. How did you manage to be so much in sync with the real-time data from another website? The content-type: text/event-stream renders data to the client but it's a mystery how your server is performing the reads with barely any delay. You might be perhaps reading the public web socket data and mapping that to your server but ideally, this shouldn't be possible at all. This is also possibly your selling point so good luck!
