This is the frontend only. It does not connect to FYERS yet. The live feed, server-side credentials, automatic reconnection, resubscription and durable storage must be implemented in the backend before this chart can be used for live analysis. Not every underlying has listed options; the backend must validate the selected market, underlying, expiry and strike against the current FYERS instrument master before subscribing. A 500 ms UI refresh target does not guarantee market-data delivery latency.
