Like i promised, on the 31st of Jan, here i am with the a spread sheet that will capture data from the nse-india.com for prev day as well as current day, so this what you will have to do. There are two button called 'Previous' and 'Current', now when you start your day at around 10.00, click on the 'Previous' button, you will need to do this only once as these values will remain constant. Now at 10.15, click on 'Current', this will give you todays H/L at THAT POINT IN TIME, again at 10.35, click on 'Current' and if there is any change in the CURRENT DAYS H/L, it will captured. The steps are specified below.
Open the file (Nifty.exe)
Go to the tab BhavCopy
Click on Previous (this will get you Previous days H/L)
At 10.15 click on Current (this will get you Current days H/L till 10.15)
At 10.35 click on Current again (this will get you Current days H/L till 10.35)
Go to tab 'Levels', it has data for all the 50 stocks of NIFTY, including buy and sell levels.
I am still in the process of getting the levels for current months Nifty, as soon as that is done, will post an updated sheet.
Like i said before, this my way of thanks to Dhirajji and Sunil....
