    Workspace Corruption when Making Changing Chart Instrument

    I use IQFeed with NT. Invariably when I am doing some changes with the workspace, especially after hours or on weekends, I end up with a situation where NT has a Loading message on the upper-left. It does not however load the data for whatever reason. However if I try to save that workspace it gets corrupted and some of the charts go blank the next time I reopen the workspace.


    Today I made some changes in my charts to rollover to the new futures. There is also an RTH 30 min chart in this workspace. When I tried switching that instrument, I ended up with the Loading message. I unfortunately saved the workspace and now it is ruined. A number of charts now have the Loading data... message, but the Instrument is not selected (i.e.you see the string Instrument and 1 min) but nothing loads. The right click menu also does not appear. Selecting the instrument from the drop-down menu also does not change anything. It is as if these charts are no dead windows, stuck in some strange place in the code. You can see an example of a window in the attached image.

    Note that some of the charts load fine, but some do not. The offending 30 min RTH chart loads fine with the old instrument.

    I unfortunately do not have a working copy of the current workspace and will have to recreate it; it has 22 charts. What would have saved the situation, is if NT created a backup copy at Startup which I could have used to rollback.


    With the whole slew of multi-threading enhancements added to NT7 these errors are not unexpected. However what I really hate is losing a lot of your work because NT sputters at a point. To add fuel to the problem, NT has stopped prompting for backups; a few releases ago it would prompt for backup every time you would shut down.

    Till NT7 reaches a point where data-handling, switching instruments etc. is seamless and at least does not corrupt the rest of the system, could you please do a quick back up of the:
    ->Workspaces
    ->Templates
    and other related xml files related to the creation of charts and workspaces, at STARTUP, from which you can selectively restore any file which gets corrupted? The current backup-restore does a complete system restore. What I want is the ability to selectively restore my workspaces to the status they were before they become corrupted.

    Restarting NT (a few times) seems to have sold the problem
    So I did not have to recreate the 22 charts again.

    However, I do keep on facing this problem of dead charts much to often to be a happy camper.

      Hello aviat72,

      Good to hear the issue is solved for now.

      Please note that you can create backups of only your workspaces as well. Only select ' Workspaces' in the backup window and run the backup. I suggest to do this as soon as you rebuild your workspace.

      In addition, please let me know if you find reproducible steps that cause charts to get stuck on loading data.
