Thanks for your prompt and informative answer, Gary. Since I have just a subscription to tick data, but no API, would it be possible to get a printout of the STC command? If I am breaking any rule with this request, please feel free to say so. Thanks again for your help ad assistance. Edited by arturo didonna on Mar 30, 2023 at 06:17 AM

I am trying to figure out the meaning of the trade conditions reported in iqfeed prints. For instance: 2023-03-27 15:43:58 0.55 2000 2009 0.51 0.57 569841655 C 16 AB What is meaning of the code 'AB' reported in the last column of the above SWKS2321D125 times&sales? Thanks in advance.

Wrong price in Times & Sales Apr 17, 2019 03:26 AM
(Total replies: 1)
I have found several instances of wrong price at which a stock was exchanged in Times&Sales from iqfeed. For istance this is CSX on April 3, 2019: 28467 2019-04-03 13:24:55 75.595 350000 4002311 75.59 75.6 4462 O 19 8944 48295 It is impossible that the reported price, 75.595, is correct because such a tick increment is not allowed (minimum is 0.01) Another example of wrong report is OC on April 16, 2019. For the same above reason, it is impossible that the price was 53.445 8644 2019-04-16 15:57:17 53.445 7000 922919 53.44 53.45 1278558796 C 19 01 57437 The Time&Sales from Interactive Brokers instead shows a correct price for these trades, i.e., 75.59 and 53.45. Could you please double check? Arturo

Unfortunately, this kind of problem repeats itself and could be even bigger. Yesterday , the times & sales of AKRX July Put 12 AKRX1820S12, gives this exchange: "6" 2018-06-15 13:11:02 1.25 3000 3026 0.95 1.15 132599051 "C" "108" "27" So it is still a spread (SPRD) but there is no other leg of this spread in yesterday Puts. So I wonder what's going on and I would greatly appreciate a your investigation on this matter.

api to determine what options for an underlying traded during the day. May 6, 2018 12:30 AM

I agree that this is a very good idea, especially if also a minimum amount of traded money could be parametrized, i.e., get all the options that today traded more than 50000 USD. I was wondering if you guys are still considering implementing such a feature. Thanks for your consideration.

I was watching yesterday the times and sales of the Septmember put 5 and call 20 on AKRX. At 11:11:12 there was a paired trade on them that was labeled with the code "27", which according to documentation stands for: "27 SPRD Spread - Trade in Two Options in the Same Class (a buy and a sell in the same class)" But in this case the two options are not in the same class, since one is a call and the other one is a call. Is this a mistaken report by iqfeed? Thanks in advance.

Thanks for your answer. How do you know when parsing the string, that it is not the first digit of the year?

In order to filter out already expired options, I was reading the iqfeed guide to options symbols: https://iqfeed.net/symbolguide/index.cfm?symbolguide=guide&displayaction=support§ion=guide&web=iqfeed&guide=options&web=IQFeed&type=stock From what I understand, the letters before the first digits in the symbols represent the underlying. Then comes the info on the expiration data, with the first two digits representing the year, then 2 digits for the day and a letter for the month code. Then there are digits represnting the strike. So a code like CSCO1220V19 means Cisco October Put at 19.00 Expiring on 10/20/12 But why other symbols, like A11720A27.5, representing Agilent Call 20 expiring on Jan 20 2017 have an extra digit ('1') after the 'A' symbol? It doesn't make any sense.

I was looking at times&sales data for the option DIS1716F120. I noticed a jump in the TotVol column with no activity in the LastSize column. Is there any way to recover such missing data?

Many thanks to Jay and Stan for their answers and for making clear DTN transition plans. If I understand correctly there is no workaround for this problen before the end of January or February 1st. Is that correct? Edited by arturo didonna on Dec 8, 2009 at 10:44 AM

New option symbols Dec 8, 2009 09:57 AM
(Total replies: 20)
Hi. I am an option trader. The CBOE recently switched to the new option nomenclature. For example, the new symbol of the OVTI 2009 Dec 12.50 Call is now UCM0919L12.5, whereas it used to be UCM LV in the old format. Unfortunately, DTN is still using the old format (I am accessing it through QCollector program). Therefore, I am looking or an utility that takes as input a list of new symbols and outputs them in the old format. Even a side by side list would suffice. Thanks in advance.

Problems with Times & Sales data Nov 23, 2008 01:08 AM
(Total replies: 3)
Hi. I am working with option Times & Sales using the QCollector software. I noticed that often it is not possible to figure out if the exchange was made on the bid or on the ask. As an example, please have a look at transactions made at 10:00:34 on April 2009 call 32.5 on Target (TGT). The first of these transactions consists of 800 pieces that are reported to be exchanged at 4.64, whereas the bid was 4.35 and the ask 4.55! Similarly, the other transactions at this time don't make any sense because of the inconsistent figures of last, bid and ask prices. I was wondering if there was any fix to this problem with Times and Sales data. Thanks in advance. Arturo |
