Dear, I 'm trying to create a composite whit the Downloader, but I receive an error message and I'm not sure to use the right way.. I'd like to create an Advance/Declining composite and I following these info: {To display the Advance Decline Line, create a composite security in The DownLoader of Advancing Issues minus Declining Issues} Here what i did in the Downloader: File --> New --> Composite I fill in a new name, I select the Primary and Secondary symbol (Metastock format) and choose Subtract the I choose create, but this message appears: "Add or Change would duplicate an existing security" and the downloader stop me, but ther's no security with the name I choose. If I try to display the result with Datasheet command it works, but I'm not able to create it. Any suggestions? Thank you. :(
