This would be done with a scan. Let's assume that we have 3 quotepages, and we want to create a single quotepage which contains all the symbols in those 3 quotepages. We'll assume the names of our quotepages are SP500, Nasdaq100, and Dow30. Create a Scan (Setup: Scans) with the following syntax QP = "SP500" OR QP = "Nasdaq100" OR QP = "Dow30"
This basically reads "Symbol is either in quotepage SP500, or symbol is in quotepage Nasdaq100, or symbol is in quotepage Dow30". Run this scan on the ".All Symbols" quotepage and the result will be a quotepage that contains all the symbols in all 3 quotepages. If a symbols exists in more than one of the quotepages, the symbol will still exist only once in the resulting quotepage.
