no, you dont need to use magic number, except you want to distinguish each of them.

You need magic number if same pair.

depending on how EA calculate orders

if EA compute globally, the magic number is not working

if EA calculates based pair, then the magic number is not working

point

depending on how "EA" calculate total order
