Magic number of 2 EAs in same MT4

[migen]

I read the manual on Fxdreema :
For example, you can have Expert Advisor A who creates EURUSD trades with Magic Number 123 and another Expert Advisor B who creates EURUSD trades with Magic Number 456. When you look at the list of trades in MetaTrader you will not be able to recognize which trade is created by which Expert Advisor, because magic numbers are not listed, but Expert Advisors can and they should do it.

So when I create EA, I will chose
Group Mode : Group #
Group # : ... let it empty

So the EAs will not mess with each other. Is it right ?

This is the base magic number for the EA:

If Group is empty or 0, this will be the magic number of the trade, let's say 6927. This is also that input parameter of the EA called MagicStart (I know, stupid name). If you use Group number 1 for example, the magic number will be 6928.

You can see the magic number when you put the mouse over the arrow icons of each trade.
