I am looking for a data feed with an API that allows me to do order book analysis on Eurex. This requires a data feed with an API that allows one to enumerate every single order book update (including trades) in the order it occurred. An added plus would be exchange time stamps with high resolution (i.e. milliseconds or smaller). To do this for Eurex, that means that the vendor either has to subscribe directly to the Enhanced Broadcast Solution (EBS) at Eurex [members only so unlikely that vendors subscribe to it] or to the CEF ultra+ Eurex feed from Deutsche Börse (this is basically just EBS + trade recovery) [for non-members such as vendors]. I could find only a handful of vendors on the website of Deutsche Börse that are connected to the CEF ultra+ Eurex feed (one of them is CQG). Another important part is that the API must allow one to receive order book updates and trades in a synchronous manner so that the correct order of events can be ensured. Also no updates may be missed when the thread that the event handler is raised on is blocked (e.g. due to long processing) [i.e. the API instead queues those updates]. The only data vendor I've found so far that seems to meet both these requirements is CQG (waiting for confirmation from CQG). Please share your experience with their API if you have any. Are there any other out there besides CQG that meet my requirements?
