I noticed for the last 2 days that pricing and time was delayed by up to 20 seconds when I had 2 instances of a widget/light-weight app, called desktop clock. I compared the time on the chart to my local time on in the tray, as well as desktop clock time as well as Think Or Swim time. Sierra Chart pricing lagged Think Or Swim pricing and SC time lagged TOS, windows time and desktop clock app time. The first time I noticed this was yesterday and I closed everything down. Today I noticed it again. Both around 9:40 AM EST. This time, I only closed the Desktop Clock instances and the time and pricing on SC resolved.

This is very concerning, as I saw pricing of 7620 on SC while it was 7616 on TOS for the ES contract.

This doesn't imbibe me with confidence.

Please know also, that I increased my Windows Time Sync to 17 minutes from the standard six hours because I was noticing slight time lag on Windows Time versus SC time.

Is there a suggested Time Sync frequency?

Thank you in advance.

Consider using the free DS Clock for a time/clock widget, been using it for many years, no problems with Sierra.

I also use the utility - Dimension 4 - and that checks and if need be resets my PC clock every min to the exact time.

Both work really well.

Fantastic!
Downloaded, installed, running.
Seems light-weight.

re: Dimension 4
Changed Sync Frequency to 1 minute, as per your response.
Any thoughts on setting for 'Maximum Correction'. I'm otherwise keeping it at the default: enabled and 1 hour

Thank you so much.
Gary
