"I just wanted to say how happy I am with your service.

IQFeed 3rd Party Software Support » Trade date problem Nov 28, 2006 05:31 PM (Total replies: 5)

Thanks guys. By the way Stan, be sure to be watching the symbols well before the market opens. If you start up the feed, say, five minutes after the opening bell, the problem will not occur---ever. (Which, in my opinion, rules out the "dropping of data" theory). And, to reiterate, it only occurs with symbols that do not immediately start trading at 9:30-est.


IQFeed 3rd Party Software Support » Trade date problem Nov 28, 2006 04:47 PM (Total replies: 5)

I have gone back and forth with support on an IQFeed/IQConnect issue that I wonder if anyone else has experienced this, and what the solution is. I am watching about 1500 symbols in an application that connects to IQFeed. The connection is established hours before the market opens, watching all symbols, so it sits and waits. Every day, after the market begins trading, about 20 to 30 symbols never change their "last trade date." This date remains the previous session date, and never updates.

However, this only occurs with symbols that take a while to open (e.g., NYSE 1 to 3 character types). I have NEVER seen this trade date problem happen with stocks that open instantly. If I shutdown IQFeed and reconnect, all symbols then work fine for the remainder of the session, the trade dates are correct.

I need to know the last-trade-date to determine when the stock is actually trading. Problem is, if there is a delay in opening, the symbol usually does not update the date. Tech support tells me they cannot reproduce this problem. Can anyone else?
