Post From: >255 simultaneous open charts breaks the Windows Operating System

Opening the last of my 5 CBs, more than half of the charts get lost/discarded without any error message being displayed. This error message should be in the Message Log: "c_Chart::CreateDetachableWindow: Error creating the MDI child window." If I re-save the chartbook, they are lost completely and I have to restore the .CHT from backup.
Yes this does make sense. The problem seems to be that SC breaks in some way when loading a .CHT that brings the TOTAL number of loaded charts across all CBs past some threshold. It may be coincidence, but the threshold appears to be at or near 255 total charts loaded. This is a Windows limitation. Not with Sierra Chart. The problem is not lack of system resources. Certainly operating system resources. Quite ridiculous Microsoft cannot handle this. The only way I know in SC to show 15 different price series on the same chart is to have 15 different charts for all the source series, and reference them with overlay studies. Most of the charts in the big CBs are used to supply data series to other charts thru the Overlay study. This is no longer needed now with the new Add Additional Symbol study:https://www.sierrachart.com//index.php?page=doc/StudiesReference.php&ID=400&Name=Add_Additional_Symbol We are fairly sure we did mention that study to you previously. So not sure why you are not using it. So 2 solutions have been presented to you. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users.
