"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.

"I have to tell you though that using the IQFeed API is about the easiest and cleanest I have seen for some time." - Comment from Jim

"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom

"Awesome response, as usual. It is a sincere and refreshing pleasure to do business with DTN, compared to your competition." - Comment from Ryan

"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike

"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob

"If you want customer service that answers the phone, your best bet is IQFeed. I cannot stop praising them or their technical support. They are always there for you, and they are quick. I have used ****** too but the best value is IQFeed." - Comment from Public Forum

"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email

"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe

"I used to have *******, but they are way more money for the same thing. I have had no probs with data from DTN since switching over." - Comment from Public Forum Post

Author	Topic: Determine NYSE Opening Tick (6 messages, Page 1 of 1)
svftech -Interested User- Posts: 5 Joined: Apr 17, 2009	Posted: Mar 1, 2010 12:54 PM Msg. 1 of 6 I need to determine which tick is the NYSE opening (ie the first one the specialist executes, not the first tick after 9:30 EST). I tried using the NYSE designator, but trades are executing with this designation before the actual NYSE open. I the meantime, I've been using sort of a fuzzy logic to look for a large trade but it is not definitive. Any suggestions? Thanks, Steve

svftech -Interested User- Posts: 5 Joined: Apr 17, 2009	Posted: Mar 1, 2010 08:21 PM Msg. 3 of 6 The Open field is reporting the first trade after 9:30 EST as the Opening trade, even for NYSE stocks. (this makes sense for NASDAQ stocks since there isn't a person doing the opening) The opening trade by the specialist is often up to a minute or 2 more after 9:30 EST. This is critical for my application to determine what the specialist has opened the stock at. I am able to get this data from other feeds (I only mention this so that you know it's available from the NYSE exchange). Is there a way to get this from IQFEED? Thanks, Steve F

However, I will send this over to our market data group for verification.

svftech -Interested User- Posts: 5 Joined: Apr 17, 2009	Posted: Mar 2, 2010 12:42 PM Msg. 6 of 6 No need to change the way your opening field is calculated for your datafeed, it is correct as is. What I am looking for is that either there is another datafield (ie. NYSE Specialist OPENING Trade or one like it) or one could be added as an option in a future release (hopefully soon). I'm assuming the specialist's opening trade is another data field provided by the NYSE because my trading platform has an OPEN field that does not get populated with a value until the official NYSE Opening trade is executed by the specialist. My primary intent here is to get the NYSE Specialist's Opening trade because this tells me that the specialist for this stock is now open for business and the trading in this stock is fully liquid. The specialist's opening trade for larger stocks is usually over a million shares in one tick and it is easy for me to identify, but the smaller cap stocks are not as obvious. Thanks, Steve F.
