Hello support team
I hope you are doing good and sorry for asking you this question on an irrelevant thread.

Today during RTH open, I experienced a massive 1.1 minutes lag of data across all my charts and this lag lasted for almost 20 minutes and even after that my charts occasionally turned yellow “Downloading intraday market data” then blue “Downloading intraday market data” and then green “Intraday Data Download complete”. After a few minutes, it keeps repeating.

I checked my internet connection, it shows my internet speed is almost 1000 mbps. I checked my task manager, sierra chart is using just 0.2 mbps. If the server-side queue was large my software should have increased the bandwidth usage.I used to notice 3-5 seconds of delay and it has already been normalized to me but 1.1 minutes lag is a huge deal so i decided to talk to you.

Is there any way to make Sierra Chart use more bandwidth? Is any settings blocking this for me?
Also, was there any issue with Sierra Chart servers during RTH open (9:30 AM ET) on default servers?

And is there anything you would recommend me using for the delay?

At 10:55 AM (ET) the yellow - blue and green switching has stopped.

Sorry if this created any inconvenience to you
