From what i have seen in last few days is Quotetracker isnt backfilling the intraday data, it fetches the intraday data alright when you are online but the part when u were offline or not using QT is conspicously missing. Before the recent NSE update ( when NSE altered the get quote link & shifted to AJAX a few days back) backfill use to work well, maybe we need to mail the support guys about this issue & seek clarification from them. QT support is good i guess we will get a reply soon.
And plz dont call me sir, i m just a beginner in this field...
