I am using Ninja Trader 7 with Rithmic data feed and have been experiencing periodic freezing of the feed, or some may say it just hangs. Yesterday was pretty much through the RTH, from time to time the data stream would freeze for 5 or 10 seconds, then accelerate and catch up to real-time. Tried disconnecting, shutting down, disconnected from ADSL, nothing made a difference. After the usual opening period activity slowed down, it wasn't so bad. Today started off the same, very frequent freezing when the markets opened, so I disconnected from the feed and re-connected. After that, even through the frenzy of selling at 10 ET, it did not miss a beat - as perfect as can be. I'm pretty certain it is not my internet connection, tests return the usual performance metrics, and today it was the same connection before and after. I have no idea whether it is the data feed or an issue from the exchange itself (CME). Does anyone else experience this? Any advice on how best to handle?
