ragh_ash,
quotetracker shows intraday-data only if it is downloaded during market hours. After market hours it cannot download any data as no data is coming from NSE. Even during market hours, If you start qt at say 14.00hrs, data will be collected from 14.00hrs. Thus it is necessary to keep qt on from 10.00 t0 15.00hours if we want to get full day data. Back filling of intraday data is available only from paid venders if we are their customers. Auto button gets intraday data continuously whereas manual button gets data only once, during market hours.
Regarding historical daily data, yahoo gives data if configured accordingly.
