"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

IQFeed Developer Support » Bid and Ask price and Size Missing for SPY Dec 18, 2007 12:39 PM (Total replies: 1)

The DIA, SPY ,GE ,IBM are not showing bid and ask prices, the string shows 00 on the number field that they are supposed to be in (11 and 12) I do get the QQQQ completely and the MSFT too. I wonder if this could be a problem in my end do to my subscription?

A tried the VB, C# examples and the DDE that you guys provide and the problem persist. So I discarded it had to do with one of our applications.

Any suggestions will be appreciated.

IQFeed Developer Support » How do I retrieve minute bars in real time Sep 17, 2007 03:13 PM (Total replies: 1)

Hello guys

I got a question about IQFeed, How do I retrieve minute bars in real time ?

is there any command that can do this? I already get tick by tick, by I need the entire bar, such as 1 , 3, 5, 10 15 etc minutes, since I dont want to compute this from tick by tick.

I've seen there is a way to retrieve minute bars in Historical Mode (HM,[Symbol],[Days],[Interval];), but I need retrieve data in Real Time.

Can anybody help me with this?

Thanks.

IQFeed Developer Support » Market Depth? May 9, 2007 12:50 PM (Total replies: 1)

I wonder if I can retrieve market depth for CBOT or any futures market? and could you please specify the way the string comes in, becuase I did not find anything related to MD

Thanks


I could not find any documentation on how to retrieve market depth nor the events nor methods, also how often does the time stamp updates?

I'm not interested in the Level 2 data from nasdaq. I want detailed futures market depth.


Thanks

IQFeed Developer Support » Implied Volatility and the Greeks? May 22, 2006 04:50 PM (Total replies: 1)

Hi, I wonder if Iqfeed provides the Implied volatility and delta, theta, vega and gamma for every strike on the options chain?

IQFeed Developer Support » OPRA T&S Dec 20, 2005 02:22 PM (Total replies: 1)

One last thing, Is there a way to recieve historical Tick by tick information for an entire chain of an option Symbol?

I'll look forward to your reply

Merry Christmas

IQFeed Developer Wish List » Level 2 history data Dec 16, 2005 12:12 PM (Total replies: 1)

It would be amazing to have level 2 historic data ( 5 days of trading), since none of the provider ( not even bloomberg or reuters have it)

IQFeed Developer Support » Historic Level 2 Dec 16, 2005 12:09 PM (Total replies: 2)

Hi I know I can get history tick by tick and size per trade with level I. Bu I wonder if there is a way to request Historic Level 2 ?


I'll look forward to hear from you.


A) Hi I wonder if its permitted by Iqfeed policies to distribute the developers API in my third party application instead of giving out the client API.

B) I always wonder what is the difference between the two?


As of 06/07/2005 I could not found the 2.3.0.3 beta?

what is the difference betwwen the 2.3.0.4 VS the 2.3.0.3?


I kind of figured out why the iqfeed control crashes right after you login.
In the login form, right after i click Connect, if i just wait for the control to login to the server everything goes ok; but if i click everywhere else on the screen (and lose the focus of the login form) the IQFeed Control crashes after the login is complete.

IQFeed Developer Support » end-of-day data file Jan 24, 2005 11:51 PM (Total replies: 9)

JAY, you are saying that you can package any future or stock symbol, in a comma delimi format with the time, price and volume just like a T&S for commercial purposes?

Where can I get a qoute of the pricing for an entire year of a particular symbol?


same thing happens to me, under visual basic, and sometimes i get the WASEISCONN error from the IqfeedY control

IQFeed Developer Support » Incorrect data from IqFeedY OCX Component Dec 9, 2004 02:48 PM (Total replies: 1)

hi, im using the newest version of the control (2.3.0.2), but when i download many symbols at once such as @ESH5, CSCO, SPY, @ESZ4, @EUH5, etc... many times the string that arrives from the activex control comes incomplete; and when that happens, theres some information missing (i get values out of a certain field, like the time(18), and from there on, the string contains nothing) ; it looks like somehow the control saturates, because it happens when there is a lot of activity in the market.

this behavior was also present using sockets, but it appears to be less frequent in computers with more speed and ram.

Do you a way in wich i can somehow "mask" the values that i request, so i just get the information i need?

Thank you, i'll look forward to your reply

IQFeed Developer Support » IQFeed Client crashes after connecting Aug 11, 2004 11:18 AM (Total replies: 5)

Im using the newest version of the controller (v2.3.0.2) but it happens whit all the previous ones

IQFeed Developer Support » IQFeed Client crashes after connecting Jul 30, 2004 12:25 PM (Total replies: 5)

I have a problem whit the IQConnect.exe, after i input the login/password and the client connects it crashes sometimes (it happens even with the samples provided by iqfeed), do you any idea of how i can fix this issue?


I wonder, how can I compare if the total volume traded I recieved from Iqfeed on the e-mini S&P matches the Volume posted on the website of the CME Time and Sales of Globex during a particular day?

Since I dont understand what update different that the t, T, b or a....... is happening with the o caracter? I cannot know whether it could be a real trade or what?


The HH represents the hour of the day in a 24 hour clock. MM represents the minutes of the hour. The character represented by c indicates one of the following:
t - A trade update occured
T - Extended Trade.
b - A bid update occured (an ask update may also have occured)
a - A ask update occured
o - Some other type of update occured

Could it be possible that if the o caracter appears it could mean there was a trade?


I have no way to know if the transactions I recieved are being duplicated? Do Iqfeed assigns an id number to each tick? Since yuo do not give the seconds at which the transaction took place its harder to identify if some trades are being duplicated!

The HH represents the hour of the day in a 24 hour clock. MM represents the minutes of the hour. The character represented by c indicates one of the following:
t - A trade update occured
T - Extended Trade.
b - A bid update occured (an ask update may also have occured)
a - A ask update occured
o - Some other type of update occured


In a simplistic example of two trades could you please explain the difference between a Trade update scenario and one with a Extended Trade?
