Your question is Real-Time Stock Dashboard. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Design a real-time dashboard that displays stock market data with minimal latency.
Explain how market events reach the browser, how the system handles reconnects and out-of-order updates, and where ML could add value without delaying price display. Cover the client architecture, streaming and storage layers, model serving if used, capacity estimates, monitoring, failure handling, and offline and online evaluation. State your assumptions and clarify which data must be real time versus eventually consistent.
