takes a long time (several minutes) and get a non-responsive message while opening and closing and saving sierra charts in recent versions. i went through and closed chartbooks and reduced days loaded but to almost no avail. also tried reinstalling earlier versions but many of my settings and and charts and studies would disappear. what's up?

We are not aware of any issues which would create a performance problem.

We do not observe any issue ourselves. We have heard about one or two other reports of this but do not know what the particular cause is and in general, we would not expect this to be a problem. If anything we would expect the exact opposite.

but many of my settings and and charts and studies would disappear.
We do observe a problem where not all charts are being opened from a newer Chartbook in an older version. We are looking into this now.

Do not be concerned about this. We will resolve the problem and there are backup Chartbooks available.

Just give us a couple of hours.

yes i've already rebuilt using the backups -- and that is fine except that even they dont rebuild the control bars that were ruined - i had to reprogram those by hand.
re: performance issues -- if you've had several then there are probably more. even i wasn't sure that it might have something to do with SC until i had upgraded 2 or 3 times this past few weeks. i thought my computer was malfunctioning. maybe something to do with the studies i'm using? or the new spreadsheets?
i employ heavy amounts of study/price overlays (9 per book), with one spreadsheet system/alert with 4 entry/exit formulas in each book (minimized to 1000 rows), but only 4-6 books open simultaneously, and drawings copied from charts in some books to other books. I've cut it down to that - before with earlier versions of SC and even heavier settings (default 10000 rows on spreadsheets) I had 10 books open. Earlier versions of SC (1510s to 20 and before i think...) had no problems -- with all books open they were slowed a little on opening and closing and autosave but only by 10-15 seconds. Now it is literally 3-4-5 minutes or longer. I checked to see if it was cpu (core i3) or ram (24gb) that was the bottleneck but it was definitely the cpu maxed out at 100%.

Were the control bars part of a detached chart?

Not sure why there would have been a problem with control bars in any case.

When you mention a backup are you referring to a backup Chartbook?

Provide us one of the Chartbooks and we will test it and see what the problem is . Attach it following these instructions here:
https://www.sierrachart.com/index.php?page=PostingInformation.php#AttachFile

We will also need the associated Spreadsheet file.

We released version 1536. Chartbooks saved in this version which use Chart Drawings can now be opened in older versions.

We still need one of your Chartbooks and the Spreadsheet to determine what the performance problem is from.

control bars not part of a detached chart; what i had to rebuild was the references to chartbooks which were decimated by the version upgrade; also the specs I had built into some of the tools. a chartbook and spreadsheet are attached.

We have not had any time to look at this. Allow several days.


We do not know why there would have been a problem with Control Bars. We do not observe any problem with that after updates to newer versions and then going back to a prior version (1525) and then updating back to the current version.

Hello,

Don't meant to interrupt this thread but I thought I should point out my performance issues I am having with SC. I will post a separate thread in the coming weeks after I take some time off trouble shooting and focus exclusively on trading.

I recently upgraded from version 1209 to 1522. After recompiling all my custom studies (all 20 - most are very small) my cpu would stay at 30% - sometimes even after I disconnected from my data feed. SC would sometimes freeze up if I tried to change a setting because of the high CPU.


Now I finally got the older version 1209 back up and running. Same chartbook - my cpu is now between 10% to 15% with 20% spikes (Intel i5 running Windows 10). Life is great!


I also use overlays, displaying chart drawings on a different chart and use many chart drawings via custom study. I will have to do more testing and trim down my chartbook so you will have a chartbook to test. I eventually want to use the current SC version. I thought I should explain that there are some issues here that will only show up when SC many advance features are being utilized.



Thx,
--WT

You just have to use the backup Chartbook file which was last saved from the version before the update. Refer to:
Chartbooks (Workspaces): Accessing a Backup Chartbook File

You do not need to rebuild anything.

Your Chartbook and the spreadsheet attached in post #6 opens for us in 5 seconds. No trouble at all.

This is using the current version.

There is work being done on spreadsheets which could cause a performance issue and that will be improved upon but we would not expect such a drastic difference in performance.

So at this point, we are not really sure what the problem is in your case.

Yes I understand what you are trying to say....that's the procedure I followed when I replaced the corrupted chartbook with the backup chartbook...However -- the control panel references, meaning the buttons referring to CBs I wanted them to open all disappeared, and the specs I had programmed various drawing tools all disappeared (color,line type settings, stuff like that), and still had to be redone by hand. And even replacing the corrupted cfg with the backup cfg files didnt bring them back.
Whatever. Not important any more. Everything's back to normal. Just thought you'd want to know. Thanks for helping.

Since Chartbook Control Bar buttons are new, those were probably not supported in the version you went back to.

And due to enhancements with drawing tool configurations, those configurations also might have been lost with going back to a prior version.

We do apologize for the issues. Unfortunately as we make changes and enhancements, there can sometimes be some back compatibility problems in certain areas. Although generally this is not the case.

In regards to post #10, the CPU usage should be next to zero when disconnected from the data feed unless charts are redrawing for some reason.
