Hi Petko,
I thought exactly the same when I read that comment as a portfolio EA trades the same symbol and timeframe so would not change anything with regards to FIFO.
I am guessing what Alan means isn’t a Portfolio EA but a portfolio OF EAs for different assets, right Alan?
Although this is pretty much what’s offered in the 12 expert advisor course. Although in this course there are 2 EAs per symbol which would affect the FIFO.
It sounds like what you are looking for is something like 12 strategies each on different symbols Alan?
Of course you could use 6 from the top 12 and put those together and supplement any others you have from different courses on symbols not included in the 12 expert advisor course too.
