I don’t think you went carefully through Nithin’s answer. So, I’m posting some short excerpts from it.
In a single trading day, there are millions of such ticks recorded (remember this also includes change in best bid and ask prices) and it is technically not possible for any trading platform to show all ticks, especially live and on a normal broadband internet connection.
All trading and charting platforms will display only 1 tick per second on a chart, whereas there could actually have been hundreds of ticks in that 1 second. Since you are seeing only 1 tick on the chart, it is quite possible that you don’t see your SL or limit price that got executed on the chart (be it on NSE, yahoo, NEST, or anywhere else).
But as I said earlier, if a trade is executed you can be rest assured that the price was printed and it can be reconfirmed on the NSE Trade verification module within 5 days from when it was executed and you could also see the day’s range on the daily Bhavcopy and you will see your SL/Limit price within this range.
If you really want to see all the ticks, NSE does have Tick by Tick data feed which is a lot more expensive than the normal data feed, and will have to be subscribed to througn any of the authorized NSE data vendors (Not all of them give you tick by tick data). Also to be able to make best use of this tick by tick data, you should ideally be on the NSE collocation which would mean that your systems are inside NSE itself, so that accepting all the millions of ticks will be quite efficient.
Tick by Tick data is usually what professional High Frequency and Arbitrage trading firms use, don’t think there is anything much a normal retail trader can do with it.
