instrument list update

Good morning,
if we are utilising only the instrument token, symbol and exchange in our algorithm from the instrument list, do we need to do a daily update of the instrument list as the above parameters are fixed and dont change? or can we have a one time download database of above parameters?

    If you are fetching instrument_token for option and futures contracts.Then you can fetch it every expiry, as previous instrument_token will be allocated to a fresh new contract.
    And if you are fetching instrument_token just for EQ contract daily, then it can be avoided as these instruments_token for EQ remains the same unless corporate action.
