I'm on a gigabit connection. I have 88 symbols loaded, of which a few dozen are continuous futures contracts for CME symbols. Despite several days waiting and restarting the application several times it still shows "Downloading Continuous Contract Data" when trying to view daily charts of those symbols. Example from message log 2025-06-16 12:10:01.622 | GCU25_FUT_CME [CB] 27 Min #108 | Waiting for historical downloads to complete with the IDs: 108,

Good day, the symbol in the sole chart is CLQ25_FUT_CME and the message log has been submitted via "send for analysis"

We are seeing the following message in the log related to the Daily Historical Data for CLQ25_FUT_CME: HD Request # 165 | Error downloading historical Daily data for CLQ25_FUT_CME. The download timed out.
We do not see this at any other time, just the once. We do not know why this would be the case. Are you able to download the data in the main instance? Is this only an issue in a sub-instance? If you are having trouble in the Main Instance, then that needs to be resolved first, as the sub-instances get their data from the main instance. In this case, we would need to see the Message Log for the main instance by following these instructions (note that you need to open just a single chart for CLQ25_FUT_CME - do not open an entire chartbook): Follow the instructions here to clear the Message Log:
Message Log: Clearing the Message Log Close all of the Chartbooks with "File >> Close All Chartbooks". Open a single chart for the symbol you have an issue with through "File >> Find Symbol". Tell us that symbol of the chart. Tell us about *one* symbol only. Disconnect from the data feed with "File >> Disconnect". Connect to the data feed with "File >> Connect to Data Feed". After the connection and after about 10 seconds, provide a copy of the Message Log following these instructions: Support Board Posting Information: How to Post Your Message Log (Required In Some Cases) For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

Strange, it works just fine in the main instance, only the sub instances are having issues, I'll begin again with a clean install and go from there.

You really do not need a clean install. There should not be a reason for there to be an issue. If you have the data flowing properly in the main instance, then we would need to see the Message Log from the sub-instance that is having the issue by following these instructions again (again, only open the one chart, not the entire chartbook): Follow the instructions here to clear the Message Log:
Message Log: Clearing the Message Log Close all of the Chartbooks with "File >> Close All Chartbooks". Open a single chart for the symbol you have an issue with through "File >> Find Symbol". Tell us that symbol of the chart. Tell us about *one* symbol only. Disconnect from the data feed with "File >> Disconnect". Connect to the data feed with "File >> Connect to Data Feed".

Having only 1 chart typically works, but with chartbooks with a few charts, even changing the chart interval from intraday to daily results in a blank chart with a blue "Downloading Continuous Contract Data" message. Which message log do I send for that? I understand you're trying to address root cause but having only 1 chart per instance isn't a suitable solution. |

Hi, I've just sent a message log of a chartbook with a few charts but more than 1 experiencing this issue, hope it's helpful. I can't reproduce with only 1 chart.

This is being looked into. We do see entries that state that "The download timed out". This is unusual and engineering is looking into it.

Hello, is there any update on this please? I have updated to the latest version and historical data is still not loading reliably in sub instances.

Go to the sub instance and follow these instructions exactly: Follow the instructions here to clear the Message Log: Message Log: Clearing the Message Log Fully re-download the data in the chart by going to the chart and selecting "Edit >> Delete All Data and Download". Only use this command from the Edit menu at the top of the main window or chart. Or, in the case of a Continuous Futures Contract chart, follow these instructions: Continuous Futures Contract Charts: Re-Downloading Continuous Futures Contract Data After about a minute provide a copy of the Message Log following these instructions: Support Board Posting Information: How to Post Your Message Log (Required In Some Cases) We will then determine what the problem is.

We see this involves Intraday data. We want you to select this command to cancel the Intraday data downloads: Edit Menu: Edit >> Cancel Intraday Data Downloads And then change this setting to 1 Minute: Data/Trade Service Settings: Intraday Data Storage Time Unit (Global Settings >> Data/Trade Service Settings >> Common Settings >> Common Settings) For now used 1 Minute! Just to make sure you can get the data. There is very very poor Internet connectivity that you have. Sierra Chart Support - Engineering Level Your definitive source for support.

> There is very very poor Internet connectivity that you have. This is a Gigabit line and I will try to reproduce also with my Starlink backup. 1 minute data should be fine. If that works can I drop down to 10 seconds? |

It does not matter what your immediate connection is. You will never be able to sustain gigabit speeds, between your location and our servers. There is extremely poor Internet connectivity between your location and our servers. This is with certainty. Yes you can try 10 seconds. But tick by tick is not going to work for now.

Clarifying: I do not have time outs fetching data in the primary instance, only this issue in the sub instances.

OK, there is still is something wrong with the connectivity. Can be anywhere including your computer and affecting that particular instance like third-party firewall or security software.

I just wiped the sub instance folders and all the *scid's. My main instance has been happy pulling historical data at 20Mbps for the last ~hour, my sub instance chokes up. Is there any debugging which you can turn on (or add?) to diagnose inter-instance / DTC communication issues? There is no 3pty software running, this machine is Windows Server + Sierra Chart only. |

to diagnose inter-instance / DTC communication issues? There is nothing more to debug, the sub instance gets its historical data direct from the server, not from the main instance, and the Message Log has all that we need.My new sub-instance isn't even connecting now.
Is the main instance of Sierra Chart running which it needs to connect to? Respectfully, a problem with my Internet connections is clearly the wrong diagnosis here.
Not saying it is the Internet connection but a connectivity problem somewhere which can even reside within the operating system itself.

See our prior post. Is the main instance of Sierra Chart running which the sub instance needs to connect to?

Sorry, a reboot of Windows Server has fixed the issue with the sub instance not connecting.
