I am trying to get the quote of the NSE and NFO instruments through getQuote. I am fetching data for 500 instruments at a time and am maintaining a gap of around 1.2 s between two consecutive hits. This approach used to work well but since tomorrow I have been facing some issues. I think my IP is getting blocked after some point as I am unable to make it through to the end of the cycle. Also, it just stops without any response whatsoever. Any suggestions/guidance would be appreciated.
