Hi, everyone:

I am new for the forum and have tried few example programs. Most of them works fine
such as WatchList, History.

My question:

In addition to get real-time quote data from the sevice during market hours,
I would also like to get end-of-day data after market close to update my stock database.

Of course I can do it by writing a simple program to retrieve 1 day's minutes data for each symbol and then retrieve such information from it. But this will waste a lot of net traffic.

In order to reduce the traffic, I tried to retrieve 1 day's daily data after market close, but it gives me previous daily data not today's.

My question:

Does the service provide such an EOD data file for us to retrieve?
If not, what is the best way to get today's daily data after market close?

You can get EOD data after the market closes, but it is not available immediatly. You will have to wait at least an hour after market close. Thanks!

The best way to get EOD data currently, would be to wait till the market closes, then run through a list of your symbols and pull a snap quote. This will give you the current open,high,low,last,volume. This would be much more efficient than pulling minute, tick or even daily data in many cases. The daily data sometimes isn't available until after 7m CST due to exchange adjustments to the data.

Thank you for your help. I will try two methods:

using snap quote just after market closed and wait for daily data available after 7:00pm and see whether they have different rsult.
