1. SC v2292 is opened and disconnected from data feed, 2. Press 'Delete all data and download' on any chart, 3. SC connects to data feed and downloads data for that symbol, 4. SC deletes all data and downloads it again for that symbol. Date Time Of Last Edit: 2021-08-03 18:34:53

We just tried this and we are not seeing the data downloaded twice. What are the messages you are seeing that makes you think that it is downloading twice? Keep in mind, that there is a difference between downloading and loading the data into the system. If you are seeing the white screen that loads the data and you think this is coming up twice, then most likely you are using a Continuous Contract and it is loading the data from two different contracts which are stored in different files. This could appear as if it is doing something twice. For the most reliable, advanced, and zero cost futures order routing, use the Teton service: Sierra Chart Teton Futures Order Routing |

I'm seeing SC finishes downloading data, then it starts downloading it again from the beginning. We just tried this and we are not seeing the data downloaded twice.
I can reproduce it repeatedly. I'm not sure now, why SC does and does not connect to data feed after 'Delete All Data And Download' is pressed, my guess is that it's happening, if chart is missing new data from server. But that's just my guess, you should you that better, than me.

We are able to reproduce what you are seeing if you select the Connect button while it is in the middle of downloading the data. We will see if there is anything we can do about this, but most likely it is not going to change as it is probably related to creating another request to download the data since the Connection was restored.

You are not able to reproduce it, when SC auto connects to data feed? Does it connect to data feed, when you press 'Delete All Data And Download' or not? Should it connect to data feed, if I press 'Delete All Data And Download' or not? Why sometimes it connects and sometimes doesn't? but most likely it is not going to change
Do you yet agree, that 2nd download is excessive and unnecessary? Date Time Of Last Edit: 2021-08-04 14:59:34

The only way we are able to reproduce this is the following, which follows your video: - Disconnect from Data Feed. - Select "Edit >> Delete All Data And Download" - While the system is reloading the data and you can see the bars being drawn, select "File >> Connect to Data Feed". - The system will reload the data after it has loaded the data the first time. Yes, it is excessive, but these particular steps are very esoteric and not something that would commonly occur.

I got it, that you can reproduce only 2nd case, when SC does not auto connect to data feed, from your previous post. Why did you care to explain it thoroughly? Now you ignored all my questions, related to 1st case, when SC does auto connect to data feed. Let me repeat them for you: You are not able to reproduce it, when SC auto connects to data feed? Does it connect to data feed, when you press 'Delete All Data And Download' or not? Should it connect to data feed, if I press 'Delete All Data And Download' or not? Why sometimes it connects and sometimes doesn't? |

We will check on this.

The second full re-download should not be occurring, and we have determined the reason for the problem. This is not a new issue. It probably dates back more than a year. This is the first that we have heard of it. We are resolving this now. Should it connect to data feed, if I press 'Delete All Data And Download' or not?

I found a way, how to make SC connect to data feed after 'Delete All Data And Download' is pressed. Successfully repeated it 5 times in a row. 1. Disconnect SC from data feed, 2. Open an intraday chart from File -> New/Open Intraday Chart menu with a last modified date earlier, than current date, 3. SC downloads latest missing historical data, while being disconnected from data feed, 4. Press 'Delete All Data And Download', 5. SC connects to data feed and downloads historical data twice. |

This does not occur, unless the historical data is obtained from the same server that the real-time data is from. In many cases this is a different server. So no connection to the real-time/streaming data feed is necessary.
I don't know about the same server, but for sure SC connects to data feed, if chart is missing latest historical data, so my guess in 3d post was correct. Date Time Of Last Edit: 2021-08-04 17:58:40

Regarding post #10, that has been resolved now. We are putting out a new release. There are certain conditions which Sierra Chart will connect to the data feed. Certainly a newly opened chart will cause that. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.

There is another issue re downloading historical data. 1. Connect to data feed, 2. Open any chart, make sure historical data is downloaded for it, 3. Set from date in chart settings to an earlier date, than the date, currently determined by 'Maximum Historical Intraday Days to Download' setting, 4. Confirm re-downloading of historical data, 5. Disconnect and connect to data feed, 6. SC will continue downloading data, beginning from the date, currently determined by 'Maximum Historical Intraday Days to Download' setting, ignoring previous days. Example: There is data for 2021-06-04: https://i.imgur.com/5xCfmGy.png But SC skipped that day after performing above steps: https://i.imgur.com/AWL7opy.png Date Time Of Last Edit: 2021-08-04 18:38:33

The answer is yes in regards to post #14.

What about post #13, Sierra_Chart Engineering?

Regarding post #13 when you deliberately disconnect with File >> Disconnect, the historical Intraday data downloads are stopped and discarded. So do not do that. There is not a solution to this.
