I am getting these fields when i am fetching all Instruments:
public long instrument_token,exchange_token; public String tradingsymbol,name; public double last_price, tick_size; public String instrument_type,segment,exchange, strike; public int lot_size; public Date expiry;
Which fields are constants here for a given Index, stocks, futures or options etc. Like for Nifty 50 and all its F&O has name as "NIFTY" in response. Will it always be true? I need to know this to ensure that proper FUT and OPT tokens are selected automatically to trade every time new FUT and OPT are available for NIFTY.
