Yes NSE data is real-time and delivered candle by candle to you, directly from NSE server through a licensed datafeed and therefore is absolutely accurate as compared to any other datafeed provider or brokers charting where they only process raw data, where as in our case NSE processes the raw data and therefore is without doubt, absolutely reliable and accurate.

IntraDay timeframes supported are 5/10/15/20/30/60 min/2h/4h . So data is refreshed at every 5 min interval.The chart candle appears immediately after the 5 min candle is complete. So, for example, 10.05am candle appears at 10.05am, 10.10am 5min candle appears at 10.10am. There will not be any data update between 10.05 and 10.10am.

All the charts and other services are auto refreshed.

EOD data is duly subjected to stock splits/bonus effect once in a week and thereby is clean to analyse and interpret and here again it scores high on accuracy compared to broker delivered data/charting.
