Author	Topic: Continuity of feed data (2 messages, Page 1 of 1)
sgill -Interested User- Posts: 3 Joined: Jun 21, 2013	Posted: Jun 21, 2013 08:31 AM Msg. 1 of 2 I'm evaluating whether IQFeed will be a good fit for my application. It is critical that I receive all tick data for the symbols I've subscribed to. In the documentation I've look at so far I don't see anything ensuring that I won't miss any data in the event of an outage of some sort (DTN, ISP, my server, etc). Can you confirm whether or not IQFeed has the ability to catch up the data data that would have been transmitted during the outage so no data is missing (delayed now of course) or out of order? I had been looking at NxCore which provides this capability but I'd prefer the IQFeed API.

This historical data includes trade date/time, price, size, market center, trade conditions as well as the bid/ask price at the time the trade occurred. The tick data from history will be delivered in the same order as it was received from the exchange (which is also the same order it would have been received in the real-time streaming feed).
