Isn't that just using 'Custom analysis' and choose the magicnumbers you want?
No. I think he means combining several magics into one (group)...
I presume this was exactly what was intended in the first post and that's how I meant it too. So instead of several magic numbers you have them all in one group and this group acts like one magic number. And you could make many groups.
That would be neat for portfolio trading and/or for a system that uses many magic numbers.
You could for example, if you have several different scalpers, group them all together to form a 'Scalpers' group(they could also be seen separately at the same time).
You could have an EA that uses several magic numbers and group them all together(especially useful in portfolio trading if you have several such EAs).
This way you could easily see the overall behavior/effectiveness/etc. of each EA.
Less effort, better results.
