Hello, I was able to modify his study to my liking and i had four studies based on it. I assigned one study for each button and was able to build it. This produced four individual .dll files, (this works fine) How can i put all three studies into one .dll? under SC help, https://www.sierrachart.com/index.php?page=doc/AdvancedCustomStudyInterfaceAndLanguage.php - I did this and still unable to put all three under one .dll Any advice is appreciated. Thank you.

In the same study or same namespace.

Its much easier to help if you include all your code.

I am using "Color Bar Based on Alert Condition" and noticed that when I clicked my toolbar button to hide a group of studies, it was also hiding the colors. The reason is that calling SetStudyVisibilityState on the main price graph (ID 0) which is the default, hides the bar colors. I've updated this study to perform the necessary check to avoid this problem, and removed about 80 lines of somewhat verbose state logic and unnecessary variables in the process. Uploading it here.
