Details for Zerodha KiteConnect support report Created kiteconnect_api_details.md with: API version: KiteConnect Python Library: Version 5.0.1 APIs used: kite.historical_data() — EOD settlement OI (preferred) kite.quote() — Live/current OI (fallback) kite.instruments() — Instrument metadata Issue summary: Symbol: HINDALCO Contract: HINDALCO25NOVFUT (current month, expiry 2025-11-25) Date: 2025-11-20 Problem: Both APIs return OI = 58,571,800, which doesn't match NSE bhavcopy Scope: Only current month on 11/20/2025; next month and other dates are correct
The issue is accross all Symbol not just with HINDALCO.
We attempted to fetch historical data via the API, and it appears to OI data matches for HINDALCO25NOVFUT the NSE bhavcopy and Kite matches correctly. You may refer to the similar discussion here.
