Post From: OEC Data Suddenly Not Connecting

I assure you it did occur though - data from Wednesday 03.04 to Friday 03.07 would not update with version 1104.
The only scenario where this will occur is if the Symbol Settings indicated for the symbol that there was not data available from the Sierra Chart server. That is a possibility. And because the FIX server, where the data request would have been routed to, has very limited data, you could have experienced this.

This statement without proper explanation is not totally acceptable to a software end user.
What kind of explanation do you want? Basically how could we possibly know about a problem which is intermittent, we never observed during development, and clearly resides on the OEC side. Not sure what more explanation can be provided than that.

But, how did Sierra chart pass the FIX connection testing at first place? Just out of curiosity.
We perform our own testing which has higher standards. FIX connection testing does not reveal an issue like this. Conformance tests for professional software developers are of little value. They do not reveal actual real-world problems that you can experience. This is a basic fact that we have seen many times. No one should ever put reliance upon a "conformance test". This is an example scenario where it is not relevant.

We have contacted OEC just now with more technical details about the problem. At some point they are going to fix this. It is our impression this will be resolved in the coming days. OEC developers must be competent enough to take care of this. We have pointed out exactly what the issue is. So we are on top of this.

For now please use the older version 1078:

Any suggestions that will guarantee I will not lose my OEC data connection while I'm trading?
Yes. Please use version 1078 or earlier which can be downloaded from here:
