API data Feeds
NSE website provides data for indices realtime. Is the data via API at a higher frequency than what is available on NSE website ?
Also, can you please clarify if this is tick-by-tick data and is there a way to get access to level2/3 orderbook data ?
Not sure how fast the NSE website provides. On our end, the most active tickers get updated at up to 5 times per second. You'll get full depth of book and everything you see on a trading platform.
