The problem experienced with intermittently stopped data for some CME symbols today (2015-12-07), affected only one of our servers. You can always switch to the other server by reconnecting to the data feed: http://www.sierrachart.com/index.php?page=doc/doc_FileMenu.html#ProcedureToReconnect The conclusion at this point, is that for unknown reason, the server was not running optimally. We have restarted it. A lot of work has gone into our server software, hardware and procedures to provide reliable historical and real-time data. A situation like occurred today, was unrelated to the CME template issue yesterday and this issue was very unexpected. It is very unusual and we are not sure what the underlying cause actually was. Now that we are aware of it, we will monitor for it and determine a proper solution. Furthermore, the issue yesterday, 2015-12-06, involving not using the updated CME template for some of our CME data feed processes, has been permanently solved.

We think we found the problem. This is from one of our programmers: It has to do with a change in the CME schedule which I did not see. One of the CBOT channels is running with the old templates and everything else is running with the new templates. A small change to the decode is needed to deal with this. Generally, we used the information from the template to decode, but you really need to use one piece of info from the message header instead to guarantee the correct lengths.
We are deploying an update at this moment to solve this. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Why the CME would run one channel with the old templates and all the other channels are running with the new templates, does not really make any sense.

As we are running a review of the historical CME data we maintain, and compare it to Rithmic which is considered "good/best", we are finding that even after the trouble we had on 12-7, with high CPU loading and packet loss, still we recorded more data for NYMEX compared to Rithmic. For the January CL contract the Sierra Chart data feed is ahead by Rithmic 0.29% for total recorded volume. The shows how well our systems can handle the trouble and recover from faults. Our NYMEX data feed handler tracks over 9000 symbols. So it shows those are considered the "best" like Rithmic, still cannot 100% handle the heavy volume the CME pushes out. We beat them even after yesterdays trouble. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
