Why my connection is so poor when I went overseas. I have like 1 reconnection every 60sec with error like: - Close event error. Windows error code 10053: An established connection was aborted by the software in your host machine. - Socket gracefully closed by remote side. It is same laptop that I trade in home so no problem with firewall, also my present 5G speed test is like 395mb/s so everything is working like a charm, but not sierrachart. Connection is so poor that I have to wait like 5min to let SC download data first for 3 charts. Sometimes its faster or even no reconnection, but I can see clearly there is a problem with overloading server? Anybody have the same problem with denali? |

I have the same problem here, intermittently showing up since May 6 (not every day). My observations during RTH: - Charts suddenly stop updating, but this typically effects NOT all the symbols in a chartbook. So, other symbol's charts keep updating. This indicates that there is no network error, but hints to a server CPU capacity problem. - The problem typically occurs when there is a large number of transactions for the symbol at the exchange, e.g. for ESM4. This also hints to a server CPU capacity problem. - A concurrent ping to ds12.sierracharts.com (38.103.112.181), which is one of the involved data servers that reconnects, reports a whopping 30% packet loss during RTH. This is not only during the time that charts freeze, but a common observation during RTH. This again hints to a server CPU capacity problem, because the round trip times are pretty constant and not different from ETH. (There is no packet loss during ETH.) Do you monitor the data server CPU capacity? Do you monitor connection losses / reconnects of the data servers? I strongly suggest to review the data server behavior. If there is no CPU capacity shortage, you should look for contention in the software stack. That's all I can currently say from here with my 30 years IT experience in server hardware, firmware, OS, and software R&D. The problem should be looked at, because these problems seriously affect trading. It would also be desirable to have more debugging aids at hand for these problems. These should be built into the SC software. A standalone debugging tool may also be helpful to cut off SC software problems. Plus some kind of dashboard for the server status, e.g. like IBKR implements in TWS. |

There is no problem at all with our servers or server load. We know that 100%. The server load, typically does not exceed 5% of capacity. This is strictly an Internet connectivity issue, over in Europe. That is where the packet loss is occurring. - A concurrent ping to ds12.sierracharts.com (38.103.112.181), which is one of the involved data servers that reconnects, reports a whopping 30% packet loss during RTH. This is not only during the time that charts freeze, but a common observation during RTH. This again hints to a server CPU capacity problem, because the round trip times are pretty constant and not different from ETH. (There is no packet loss during ETH.) And it is not a server which is even responding to pings. The ping is responded to by high-performance network switches which never operate even close to capacity. We are aware of this kind of packet loss issue and we know it is a peering issue, with our primary ISP Cogent, occurring in Europe. It may not be with Cogent themselves, but with who they peer with. We are working, over the next two weeks, adding another ISP, to address issues like this. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Here is some monitoring we did before the open today and leading into the 9:30 AM US Eastern time open for several minutes by pinging one of the servers from the United States: Reply from 38.103.112.181: bytes=1 time=9ms TTL=55

The new ISP, should be online in about in about 12 to 14 days. We are also going to contact Cogent and give them your IP address.

This is 99% a peering issue with Cogent. I experience the same from Europe and can't wait for the new ISP to be online. Hoping that Cogents backbone routers are not in the trace then anymore. During Europe evenings this is really bad - during the day it's working ok.
