I'm wondering what the best way to search a universe for indicator conditions.  For example, if I create a universe of 100 symbols, what is the best way to see all of them with EMA20 > EMA100*1.05 or something like this.  From the examples I've seen on here it looks like I need to basically create these EMAs for each symbol and then I can do my compairison.  Is this right, or is there a better way?
