@admin I think you got my question wrong.

{
    "token": "37743",
    "symbol": "NIFTY02SEP2117500PE",
    "name": "NIFTY",
    "expiry": "02SEP2021",
    "strike": "1750000.000000",
    "lotsize": "50",
    "instrumenttype": "OPTIDX",
    "exch_seg": "NFO",
    "tick_size": "5.000000"
  }

In this above snippet a nifty 17500 put option is have strike value as "1750000.000000" and tick_size value as "5.000000" why ?

This JSON snippet is from this

And similarly

{
    "token": "5045",
    "symbol": "USDINR2191777.25PE",
    "name": "USDINR",
    "expiry": "17SEP2021",
    "strike": "772500000.000000",
    "lotsize": "1",
    "instrumenttype": "OPTCUR",
    "exch_seg": "CDS",
    "tick_size": "25000.000000"
  }

In this one USDINR 77.25 put option is having strike value as "772500000.000000" and tick_size value as "25000.000000" why ?

How to calculate the actual strike price and tick size from these fields ?

thanks for the awesome information.
