i have a few questions regarding instrument token. 1. who decides instrument token? NSE or Zerodha?
2. why are they not unique? i i.e. lets say instrument token 12345678 is assigned nifty 12000 call option strike price . but sometimes 12345678 is also assigned to banknifty 22500 call option strike price.
3. many times open interest data received in kite api does not match with option chain on nse website. why?
