Sierra_Chart Engineering, Thank you for your reply. What happens is related to poor Internet connectivity, not necessarily with your immediate connection but somewhere else, and the reason the data feed stops is explained here:
Prices / Data Falling Behind: 4.19 - Performing Ping Test to Determine Packet Loss and Latency I'm absolutely aware of that and I agree with you. However, I am constantly monitoring the entire path between your servers and my router and that's the reason I always know when it is an internet issue or not. Most times it is an internet issue. There is some problem somewhere along the path from your location to the server in the US Midwest.
Many times it is as you say, but today was not the case. There were a couple of data glitches just after the opening when big bulks of data came in. Also, I must say that except some rare occasions, the ISPs you are currently using have been stable and usually doing quite well, as well as the two ISPs I'm using on my side. We do recommend trying the server in Germany. Definitely keep an instance of Sierra Chart up connected to the server in Germany and see how it works. You should keep that up side-by-side and see what happens. If you notice the data feed stopping, in one instance of Sierra Chart, and not the instance connected to the Germany server, we want to know. This information is helpful to us.
I've already done that in the past and I can surely do it again, of course. I usually don't use the Germany server because the path to my location (Portugal) is much longer and so it adds some more latency due to that difference of distance. Also reading what you wrote again, a one second freeze, that is really hard to avoid when accessing data over the Internet. Sometimes this simply will happen from time to time and it just simply has to do with packet loss. We were thinking of a freeze, of more like several seconds. or 30 seconds.
I absolutely understand and agree with that. I never complain about that when it happens sporadically as I know it is normal. I've just informed you today because I know you have been improving your system and are monitoring the data feed, so I thought it could somehow be helpful. To finish now, IMHO you have been doing a great job in both Denali data and SC software. |
