Thanks, Stan. Any other tips for protecting code?

Thanks for the prompt reply. Yes, I understand the need to check for user id. On the password protection, though, I'm confused. Doesn't the password protection only prevent the file being opened in the PowerLanguage Editor, but it can still be run when applied to a chart? If that's so, then does it ...

Thanks for your replies.

Stan (or anyone else who may know), is there any added protection to protect the study using the password protection before exporting as read-only? Is there any added protection to "bulk up" the file with excess lines of code before exporting as read-only?

From what I've been able to find out, it's not currently possible to crack MultiChart's read-only study protection. Because I will be leasing proprietary strategies, I need to be sure of this. Do any of you have knowledge of how good MC's study protection is and whether it can be cracked?

Thanks.
