"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post

"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 just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin

"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

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

"Excellent datafeed !!!" - Comment from Arely

"You have an excellent product !!!!!!" - Comment from Arely

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

"I'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei

"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

Author	Topic: PCRATIO.Z Data does not match the data from CBOE (3 messages, Page 1 of 1)
swhitney -Interested User- Posts: 21 Joined: Nov 3, 2005	Posted: Dec 25, 2005 03:55 PM Msg. 1 of 3 CBOE Put/Call Ratio PCRATIO.Z [INDEX] Can you tell me what CBOE P/C Ratio this is? Upon visiting the CBOE site and downloading the variou XLS files available there through todays date, I found that none of the CBOE PC Ratios ending values correspond with the value provided by your symbol PCRATIO.Z[INDEX]. Please tell me what this ratio is, and/or what would be involved in getting the IQFeed to supply the actual three PC Ratios provided by and at the CBOE website on this page: http://www.cboe.com/data/PutCallRatio.aspx In all cases the terminating value does not correspond with the terminal value in the PCRATIO.Z Index from the servers. Further, looking back down the data chains and comparing them, it is clear that the data returned by PCRATIO.Z does not correspond to the published data at CBOE. The CBOE splits its PC Ratios into to subsets, as well as provides a combined set. The splits are for equity and index options. As of 12-23-05 the breakdown for terminal values [Daily] is as follows: Index: 1.39 Equity: .51 Combined: .69 Your terminating value for the index as of 12-23-05 is .88. Please explain what your data set is derived of, and if-when-how we can get the actual data published by CBOE into the IQFeed stream. Scott Edited by swhitney on Dec 25, 2005 at 04:01 PM

The PCRATIO.Z is for the combined CBOE put to call ratio and it does match the CBOE web site. On 12-23-05, we have a closing value of .69 (same as your example). We can look into carrying the Index and equity option put call ratios separately but I cannot make any promises one way or another at this time. -Steve
