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

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 DTN IQFeed Implementation Support Specialist
