"I am keeping IQFeed, much better reliabilty than *******. I may refer a few other people in the office to switch as well." - Comment from Don

"Thanks for all of your help. Great customer service deserves to be recognized which one the reasons I've been a customer of DTN for over 10 years!" - Comment from Stuart

"I have to tell you though that using the IQFeed API is about the easiest and cleanest I have seen for some time." - Comment from Jim

"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat

"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

"After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn

"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

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.

Author	Topic: Spinoff Adjustments (6 messages, Page 1 of 1)
Roberts -Interested User- Posts: 53 Joined: Mar 26, 2008	Posted: Apr 9, 2024 11:11 AM Msg. 1 of 6 We all know that Daily data is split-adjusted but Intraday is not. Following a couple recent large spinoffs (GE > GEV and MMM > SOLV), I noticed that IQFeed had applied a split-type adjustment for these that matched my adjustment that I apply for intraday data. I continued investigating S&P 500 and Nasdaq 100 stock histories and found that adjustments for Spinoffs have been applied in about 30 cases. I attached a spreadsheet with my spinoff findings. This isn't an exhaustive study but I've been following the S&P 100, 500, and Nasdaq 100 stocks. With a few exceptions that I can't quite reconcile the workbook has 3 spreadsheets: 1. The first are the spinoffs for which IQFeed has already applied the adjustment. Nothing needs to be done here, it's just for reference. 2. The next sheet is a list of about 65 other spinoff that I request to be applied to the Daily data. If its not possible to apply these corrections, then I want to know that, and I'll just do it myself for all of our customers. 3. The last sheet of "Errors" is a short list of spinoff that IQFeed may have applied an adjustment for, but they don't match my calculation. More investigation required. Mainly, I'm looking for action on #2. File Attached: IQFeed_Spinoffs.zip (downloaded 106 times)

There was a lot of data so it will take some time to fully investigate. I will post here when there is an update. Sincerely, Gary Stephen DTN IQFeed Implementation Support Specialist
