Do I need a separate BB Mean Reversal EA for each chart?

I just finished a basic Algo course on Udemy and one of the things we did at the end was code a BB Mean Reversal EA. It runs a check to see if there are any open trades with its magic number, and won't put on a new trade if it finds one. I have one question about testing it live on a demo account...if I put it on multiple charts so that I can trade multiple pairs, is the magic number check going to only let me be in one trade at a time? How can I be in multiple pairs with that magic number check? Would I need to code a separate EA for each pair and have each one with a unique magic number?

You make the magic number an input parameter to the EA so that you can start multiple instances of the same EA but each one can have it's own unique magic number and deal with it's own trades.
