​Client ID: AACI752461
​API URL: https://apiconnect.angelone.in/rest/secure/angelbroking/historical/v1/getCandleData
​Error Message: {'message': 'Too many requests', 'errorcode': 'AB1021', 'status': False}

​Context & Anomalous Behavior:
​Request Frequency: My code is spaced out to send exactly 1 request every 5–6 seconds (~10–12 requests per minute). This is significantly lower than the documented 180 requests/min cap.

​Immediate Triggers: The error often hits on the very first NSE request of a batch, or almost immediately upon starting a low-frequency sustained scan.

​The MCX Comparison: Under the exact same script, identical network conditions, and the same public residential IP (no VPN), MCX commodity candle requests work perfectly all day without a single error. The restriction is uniquely triggering on the NSE endpoint.

​I initially raised support ticket #29145216 regarding this, but it was closed without a resolution. Could an admin or backend engineer please check the server-side rate-limit telemetry for my client ID (AACI752461)?

​Please verify if my actual measured rate is tripping an algorithmic false positive on the NSE historical data endpoint.
