I think this egy could work well if was a kind of basket supervisor EA that can execute and manage the trades to you. For instance you could specify which GMT time to open the transactions, (Asian or London session etc) and set the minimal strength value that a pair must need to be opened etc.. The EA could select the top and bottom 3-5 pairs (you choose how many) that fit the strength standards and open them like a basket of pairs, you then set your TP and SL in pips or % etc..
