Their response seems to be a bit of backpeddaling. I think it's BS when they say futures could always go negative. Well yeah, based on the obscure way they define the fields that equal an instrument. (The MDP security definition as listed below). If that were true, then why the need to send out notices that the products were in POTENTIAL support for neg prices, if they were already designed to do so?
This is the text from the notice I got on April 5th...
Changes to Price and Strike Price Eligibility Flags for Certain Energy Products
Today Sunday, April 5 (trade date Monday, April 6), as an operational step toward potentially supporting negative pricing and strikes, the MDP 3 Security Definition (tag 35-MsgType=d) for these Energy outright futures and options on CME Globex will be flagged as eligible to trade at negative prices. The options on futures will also be flagged as negative strike price eligible.
Trading at negative prices for these outright markets will not be supported at this time. Negative strike prices will not be listed.
Negative order prices will be rejected with Execution Report (tag 35-MsgType=8) message:
- Reject code tag 103-OrdRejReason = 1012
- Tag 58-Text=<’Price must be greater than zero'>
Any changes will be published in future CME Globex Notices.
Negative trade price instruments, and negative strike price eligible instruments, are identified in the MDP 3.0 Security Definition (tag 35-MsgType=d), in repeating group tag 871-InstAttribType:
- tag 872-InstAttribValue= 9: Negative Strike Eligible
- tag 872-InstAttribValue=10: Negative Price Eligible
- tag 872-InstAttribValue= 14: Zero Price Eligible
---------------------------------
So yes, futures were always negative capable, AS OF APRIL 5TH, but who the hell can discern that low-level of coding into each instrument anyways?
And there's something else...
Last Monday when May CL went negative, it clearly showed on their quote screen that there were low limits in place on CL.
Here is what they look like on QM, as of this evening...

Low limit on QM shows .025.
On Monday last week CL was showing a very similar thing...No upper limit, but a low-limit of .01. (Yes, a penny.)
Now the Hi/Low limit column is conspicuously absent on the CL quote page.
*rubs chin thoughtfully*
