Post From: CME Data Freezing

Sierra Chart Support,

I think you should know that lately, every time that there is a significant market acceleration (e.g. when Mr. Trump tweets or "speaks"), there is an overload on the data feed causing it to freeze for several seconds (15 seconds or more) and then it keeps stuttering for a while.

Last two times were yesterday between 12:38 and 12:41pm EST and today between 8:44 and 8:45pm EST.

I can assure it's definitely not an internet issue as I'm always monitoring it.

Also, the Denali servers keep responding normally to the pings during those periods, so maybe it is some kind of choking before the Denali servers or lack of capacity from CME, I don't know.

I thought you should know.
