You can not look at only the clock for your computer and determine this. You need to understand how different your clock is from the exchange clock. The exchange uses the national standard clock. If you open your Message Log, and start looking from the top down, you will find entries that state the following: 2026-05-07 11:04:41.592 | 2026-05-07 16:04:41 Local computer time in UTC
2026-05-07 11:04:41.592 | 2026-05-07 11:04:41 Local computer time in SC Time Zone 2026-05-07 11:04:41.592 | 2026-05-07 16:04:37 Server time in UTC 2026-05-07 11:04:41.592 | Local computer UTC time and Server UTC time difference: 4 seconds. In this case (my computer) my computer clock is different from the exchange uses by 4 seconds. So if my computer clock says that it is 10:01:03, then a new bar should NOT be started yet, as the exchange data is at 10:00:59. Then, you need to look at the "Data Delay" entry in the Chart Header to see how much delay you are getting IN ADDITION TO the difference in your computer clock and the exchange. In the chart header, this Data Delay entry will be prefixed with "DD:", and gives you the instantaneous difference between your computer clock at the exchange clock. Again, you need to take into account the difference without any data flowing, which is what you got from the above. If you do not have the Data Delay showing in the Chart Header, then refer to the following to add it, or move it to where you can view it: Working With Charts: Region Data Line / Chart Header Once you understand what is occurring with the data, then you can go through the items at the following link for how improve performance: High CPU Usage | Inactive User Interface | Poor Performance | Long Time to Load Chart Data | Charts Reloading Often For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |
