Copy the whole project again or only change group number?

[duonglanh521]

I have an EA that opens a trade when a set of constants is met and there should be 1 trade at a time only. Now, I want to use that same EA for the same symbol, and just change a different set of constant. Can I just attach the EA to a new chart and change the magic number (through group number)? Or I have to copy the whole project and separate the group number within the code?

You should be able to attach to a new chart and change the MN

Thank you. I'm forward testing it in a demo account. Will post the result here later.
