End of day data feed

Hi,
I have recently started using Ninjatrader. I wanted to analysis Nepalese stocks on NT. However, there are no data provider for my country's stock exchange. The only information I can get is from the official Stock Exchange's website (ie: basic information about opening, closing, high low and volume). The quotes are end of day prices only.
Till now, I have downloaded data for a single stock and converted into txt format as mentioned in the Help guide. I update it everyday and import everyday. However as I plan to study more stocks, I do not see this method being sufficient for much longer.
A friend is writing a program for me that can update the data in each individual stock txt file. Now I need to know if there is any way I can automatically update the stock quotes when opening the program. Or if there is another better way to do it.

Any help would be greatly appreciated.
Thanks
