Accessing Reuters News Mar 25, 2010 12:10 PM
(Total replies: 2)
Hello I have the following problem: * I am registered for a trial and subscribed to news sources: REUTERS_BASE, REUTERS_PREM * However, when I run TCP/IP query: SN:MSFT::1:20100101-20100324:1000000000; I get a bunch of news, but none of them contains RB* or RP* as a source (ie Retuers) * Otherwise IQFeed TCP/IP news api works fine * Any ideas what causes this? Thanks

Summary messages on symbol registration Apr 8, 2009 10:00 AM

> was this morning the first time you experienced a problem (has it worked for you previously)? Yes, it's the first time. > Maybe a temporary network problem between you and the server? Maybe a temporary lack of processing resources on your computer (something else going on at the same time on the PC)? The problem is reproducible, so it is not a temporary network problem. I would also rule out insufficient CPU resources as IQFeed is using < 10% of cpu at the moment.

Apparently the same also happens during the main trading period.

Summary messages on symbol registration Apr 8, 2009 08:47 AM
(Total replies: 4)
Hello, Today in the morning during extended trading period, when I registered with IQFeed 1799 symbols, not all of them got a summary message 'P' in response. Some of the symbols didn't recieve any: BPOPN CVGI EXFO FBCM TAGS TUES TUNE (Yes, I am quite sure that I have indeed sent registration messages 'wSYMBOL') However, if I connected to IQFeed once more with another connection and sent eg 'wTUNE', the summary message arrived on both connections. Eventually the summary messages did arrive on their own, but it took up to 30 minutes.

Historical data Mar 2, 2009 05:44 AM
(Total replies: 2)
Hello, > The datapoint returned above (labeled 20:02:00) represents the trades that occured between 20:01:00 and 20:01:59. The request HIT,MSFT,60,20090224 200100,20090224 200100 does not refer to the interval [20:01:00, 20:01:59], it actually refers to an empty interval [20:01:00, 20:01:00). Or at least that's how I understand the semantics. Edited by gelo2000 on Mar 2, 2009 at 05:45 AM

Hello I would like to know the exact semantics of timestamp fields in the HIT request and its response. Namely, this scenario looks strange to me: ------------------------------------------------ $ telnet localhost 9100 >HIT,MSFT,60,20090224 200100,20090224 200100 <2009-02-24 20:02:00,16.7000,16.7000,16.7000,16.7000,122673954,5600, ------------------------------------------------ Asking for data between 20:01:00 and 20:01:00 returns historical data for 20:02:00? Thank You

Timestamp messages Feb 20, 2009 01:30 PM

Apparently it's happening when IQFeed get's overloaded: * I am listening for 1800 symbols on a fairly new Mac (2.5 GHZ, 2 GB RAM), running IQFeed with wine * At first it works well, but in a of couple minutes the messages start to lag * Also only then cpu usage of IQFeed hits 100% * It might be a feature of IQFeed 4.5 as I have made some (superficial) stress tests with IQFeed 4.4 earlier and there weren't such problems. Strange.

Hello, I have noticed that sometimes IQFeed misses minutely timestamp messages (see end of file). Is it a bug or am I missing something?

RT quotes Jan 30, 2009 10:12 AM
(Total replies: 3)
> Hello, an o message will contain an update to any field not accounted for in other messages types. What exactly a 'settlement' could affect? Last trade? Ask? Bid? > Other than this, I would guess that time of message arrival would be the best estimation of a timestamp for bid/ask times. Can I rely on the fact that all update messages that arrive between two timestamp messages happened during the minute implied by these two timestamp messages? Thank You!

RT quotes Jan 30, 2009 07:49 AM
(Total replies: 3)
Hello, I would like to know what fields can become updated due to an 'o'-type message: o - Some other type of update occurred Likewise, a settlement (normally an 'o' message) might come through included in a trade, bid, or ask message. Most data related issues with the feed are a result of not interpreting this field correctly. Another question: is it possible to know the time of ask/bid update more precisely than: * The one-minute period defined by the timestamp messages * The time of message arrival Can I rely on the fact that all update messages that arrive between two timestamp messages happened during the minute implied by these two timestamp messages? Thank You!

Undefined values in summary message Jan 29, 2009 10:29 AM
(Total replies: 1)
Hello, I would like to ask how would a summary message for a stock look like in the beginning of the trading session, before any quotes/trades have happened. Would it be so that fields like last trade, last trade size, ask, ask size, bid, bid size be empty? Thank You! Oleg Edited by oleg_myrk on Jan 30, 2009 at 07:39 AM

Historical tick data Jan 28, 2009 08:13 AM
(Total replies: 2)
Hello, Do I understand correctly that '30 calendar days of historical tick data' provides only trading ticks and does not provide quote updates. Also I have noticed that ask/bid size are always zero. Do I understand correctly that quote ticks are available only in real time? Thank You! Edited by oleg_myrk on Jan 30, 2009 at 07:38 AM |
