Similar to before. Is this a data problem or an algorithm problem

What's the exact Option Chains API request you're doing? And can you link to the "similar to before" problem so I can better understand what you're expecting?

This contains the previous experience: http://forums.dtn.com/index.cfm?page=topic&topicID=5949 ... the commands used, and the various results, suggestions, and then the remediation by DTN.

@ES# rolled over to a new month yesterday, so I'm now working with the new chains.

Any thoughts on a resolution to keeping the chains fully loaded with their symbols?

If I do this command right now:

CFO,@ESM22,cp,,,1


I get 1,607 calls and 1,512 puts, (3,119 total) which is far less than the 5,782 in your original post. Including the year codes 23 makes no difference to the result. None of these 3,119 symbols duplicate each other. Is the problem that there are duplicate symbols, or that some symbols are missing? Can you provide an example of an option symbol that the CFO command doesn't turn up?

This is my request:

EmitChainSummary total sum(call + put)=4810


Here is an excerpt of part of the summary. even ATM options are missing. Many calls have no paired puts, and many puts have no paired calls. I would say this is an incomplete data set. In my previous request, someone did something behind the scenes to restore the dataset. Perhaps there is a ticket for that fix you could look at?

This is still in the works. We are testing how the CEO responses are generated, and making sure it works as it should. There is definitely something that needs to be corrected, but we are still investigating.

One thing I can tell you is: don't assume that the number of Put and Call options will always match. IQFeed doesn't add options contracts until they trade at least once. IQFeed does not add options contracts until they trade for the first time. So it is possible for both "sides" of an option to have different numbers of symbols.

For what it is worth, I can probably understand the 'first trade' concept, but a few counter-facts which may help troubleshoot:

* IB has pretty good open interest on all chains in the usual trading range, so I think the 'first trade' has been triggered for many of the primary missing symbols

* in the other referenced thread, Steve was able to confirm that a 'watch' will indicate that the symbol is active and available

* all this would indicate there is some 'missing part' in the code which does generate the CEO responses. I've been able to generate a few 'flaky' responses from that that CEO request depending upon the combination of parameters provided (which yields a window into backend tooling, which, if I recall the message, seems to be Perl).

* in that other thread, someone did something in the background, and magically, all the symbols that I thought should be there, did show up.

* so.... I'd say there is an ugly bug or two waiting to be unearthed there somewhere :-) to provide the complete chains based upon what you see as actively traded options

OK, I have some new information to add here. To clarify something I said earlier:

Quote: IQFeed doesn't add options contracts until they trade at least once.


I meant "to the Option Chains command", not in general. Option symbols can exist in the IQFeed system, even if they have never been traded. So these symbols will exist in the system; a watch or historical request will work fine. The problem is they are sometimes not added to Option Chains when they should be, which leads to the omissions you discovered in CEO and similar commands. We have identified the problem and are testing a fix for it now. There is no ETA as yet, but I'll post when I have an update.

Also, it doesn't have to be traded; just having a bid/ask quote is enough. So I misspoke when I said "traded at least once."

For the record, the behavior of the Option Chains command has been improved, and users should no longer see situations like this.
