Streaming-chart-of-TQQQ-SQQQ-IQFeed-is-stuck-at-10-13-2022

Oops.... A "streaming" provider is for real-time prices and would only be possible when the market is open. Today is October 17, so streaming prices would only be available for October 17 prices during market hours.

I think what you meant is the on-demand (or even static) provider is broken past October 13. So who's your datafeed provider for on-demand and static data? Have you thought about switching to a different data provider? If you "Clear local files" in Data Manager for this provider, does that fix this problem?

That's an example of an insufficient problem report. It's okay for a new user but @drjay, you've been around since 2013. When asking for help you should include as much information as possible:

* Data provider
* Bar scale
* Symbol(s)
* Tool used: charts, St.Mon., etc
* Steps you've taken to determine it's "not working", precisely

I am using DTS's IQ Feed with 5 minute and 1 minute charts with TQQQ and SQQQ. Steps I've taken. Unclear what steps to take. I've ensured that the data range is set to al bu then it still lists the last date as 10/13/22

OK that's something, let's rename the topic title to make it sound more clear then:

WAS: Streaming is not working beyond October 13th
IS: Streaming chart of TQQQ/SQQQ (IQFeed) is stuck at 10/13/2022

Have you followed @superticker's suggestion, what's the result?

Usually when the data appears "stuck" it's because you've selected a date range that ends in the past. Check the Date Range by clicking the dates in the chart's status bar.

Tip:
Use Preferences (F12) > Data to set the default range when opening a new chart.

I am unclear how to 'clear local data'' in the data manager. I go there a locate indeed but I don't see a place to do what you suggest.

Selecting dates in preferences it is set to include all data. I double check this on the chart as well as I indicated above. I want to check the feed from DTN to make sure I am getting the data but I've forgotten how to do that. I;'ve contacted them for help. M

He means this: go to Data Manager > Historical Providers > right click IQFeed > select "Delete Local Files". The idea is to purge the local cache and then force the IQFeed provider to download all data anew. Warning: it may take some time to download 1-5 minute historical data from scratch!

OK at first that did nothing but when I restarted the app iI got current data. So now all is good. Thanks for the help. Michael

If you hadn't restarted WL prior to doing that, it's possible that choosing "Clear tracking info" (from the same popup menu) could do the trick.

The problem is, if WL freezes up during a file update, that data file gets corrupted. If that's the case, the only way to reset it currently is to "Delete Local Files".

It might be possible to create an exception handling routine that would "try" to flush all open files before WL ABENDs to avoid some of this data file corruption. That's a good idea if this is a frequent problem. But if the computer looses power, even this exception handling approach won't work (unless you're computer is on a UPS).

Another approach would be to force a purge of corrupted data files if they have been found to be truncated (missing file-end key) when trying to read them. A friendly message telling the user to "wait" while it's updating in this case would be helpful.
