Real-Time Cricket Color Trading Platform

I need a web application dedicated to live cricket colour trading. The core requirement is a lightning-fast, real-time feed so users see price movements the instant they happen and can lock in trades without delay. A websocket or similar push technology is essential—periodic refreshes will not work for this use-case.

Users will log in with their mobile number and password, so please wire the authentication flow around that. Once inside, they should be able to:

• Watch the live colour line change in real time.
• Enter a trade amount and confirm instantly.
• Have their small trading account number scanned/validated automatically before each order to avoid typos or mismatches.

An admin view where I can monitor active users, balances, and a snapshot of current colours would be helpful but can be minimal for the first release.

Tech stack is flexible as long as performance under load is solid and the UI stays responsive on mobile. Clean, well-commented code and a brief hand-off guide are part of the deliverable.
