Hi,

My script downloads latest 40 days of end-of-day data for stocks using the HDX command and I've got IncludePartialDatapoint ticked as 1 (include).

Could you please confirm that the latest data point is real-time data (close price & volume). Is there any delay implemented?

The reason why I ask is that the latest data point does not match websites that claim to post real-time data (they aren't necessarily correct). Just need to be sure what I'm looking at.

Please note that I don't have Level 1 data in my subscription. The symbols I download are listed on NYSE and NASDAQ.

Thank you,
Wojciech

The only delay with any historical command is if you are not subscribed to realtime data for the symbol you are requesting. For example, the IQFeed Core Package includes NASDAQ data, but it's 10 minutes delayed unless you add a subscription to realtime NASDAQ data. Any historical request would be 10 minutes delayed also. So HDX with the IncludePartialDatapoint parameter would give you a partial daily total up to 10 minutes ago.

Sincerely,
Gary Stephen
