The guy who prefers radio silence when there is a problem is nuts. To him it's better to wonder if it's my PC, my charts, my internet, the local internet, who knows what? He loves a good mystery I guess. I don't even have a problem with there being a problem. Sh*t happens, I get it. BUT JUST TELL ME something is wrong so I don't have to scour the internet trying to see if it's just me. It's working fine now, btw.

We have not seen any issues today. There have been a few reports, but not a deluge. For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing

OK. But, we are telling you there was though, so how do we go from here?

Around 9:30 Eastern, I too had a severe data delay. Using Denali and Teton. I was in a trade and I was closed out of the trade before price even got to my target. Then I realized that price was severely delayed on my platform. It got so bad that "Delayed" showed up next to the "DD" at the chart header. I restarted Sierra and I seems to be better.

I also experience data lag every few seconds today.

The issue appears to be related to a network connectivity issue around 2025-03-11 14:38 UTC time from our main distribution server. There may be other times as well but this was one obvious point of delay. We do not see any issue at this time. About post #35, if you are noticing a lag every few seconds, this would be unrelated to the problem.

This is an unusual problem that is rare. From what we can see it was due to temporary degraded connectivity on the circuit that carries the normalized data. The carrier has notified us that they are doing maintenance, this evening on this particular circuit which hopefully will resolve the problem. We have also put in the request to get another circuit. From a different carrier. We do currently have backups, but they are not high enough bandwidth, during more extreme market activity. And those backup circuits only get used, when there is a complete failure of the primary. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

Good news! Can there be any monitoring made on your side to detect those lags and notify users via platform? Or is it basically impossible to detect?

Thanks for looking into it. I think for a lot of us, when a whole bunch of us are having the same problem, we assume pretty much everyone is having the same problem and someone would HAVE to know. But I guess I can see how a small thing could go wrong as it did this time and no one would really know.

Try to set the following, it might improve your SC performance. To reduce the network bandwidth requirements for Sierra Chart do the following two things: 1, Set the Global Settings >> Data/Trade Service Settings >> Intraday Data Storage Time Unit to 1 Minute. 2, Enable Data feed compression. Set Global Settings >> Sierra Chart Server Settings >> Use Real-time Data Compression to High Compression. and set Remote Buffer Delay Send Time In Milliseconds (Global Settings >> Sierra Chart Server Settings >> General >> General) to 200ms global chart update interval is 500ms DOM update interval is 200ms

Yes it is impossible to detect until it actually happens: Good news! Can there be any monitoring made on your side to detect those lags and notify users via platform? Or is it basically impossible to detect? The carrier did do maintenance, that following evening apparently to resolve the issue. And we are getting a second connection to run in parallel. So if something like this happens again, much less users would be affected. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

So if something like this happens again, much less users would be affected. Would this mean that a reconnect would switch over to the healthy feed automatically? Or would it simply be luck of the draw as to which server a user connects to? In other words, what should we do when this parallel connection is in place, and when it happens again?

to sierrachart engineering team: no matter what fixes you implement present day, there is no guarantee that a different problem won't cause datafeed problems like this in the future. for large professional traders, datafeed hiccups like this could cost tens if not hundreds of thousands of dollars in losses. i understand your desire to get rid of datafeed support for rithmic (which you recently attempted but walked back) and cqg (which you already did for cme+eurex), but would you entertain the idea of allowing users to receive cqg data for cme as a backup feed if and only if they've already subscribed to denali's cme datafeed? so basically, users can get cqg's cme data as long as they've already signed up and are paying for denali's cme data? that way, you won't be losing revenue to other non-Denali datafeeds so there's no financial loss for you and users are also safer since they have a backup feed in case denali starts malfunctioning. it's a win-win for both parties. heck, if you want to make it more financially compelling for you, you can also just limit it to users of the highest package tier. after all, paying a extra 20 bucks/month or so to gain the capability of a backup datafeed is nothing in comparison to the possibility of losing tens of thousands of dollars when denali datafeed stops working and there's no backup feed.
