Not sure, but this might work. Download the NSE bhavcopy from nseindia. You will basically need the SYMBOL column from the excel and add Buy day, Buy Quant, Buy Price. Your excel should look like below:
Code:
BSE/NSE/ISIN Code Buy Date Buy Quantity Buy Price
500209 1/1/2010 50 2000
LT 15-01-2010 100 500
INE101A01026 30-01-2010 40 200
Then import that excel into moneycontrol portfolio and you will be able to see live price. Not sure if moneycontrol has any limit on how many rows can be there in the excel but worth a try.
Thanks.
