You have to adapt to your EA memory consumption. 2GB isn't a lot, and 13EA per terminal means also 13 potential pairs simultaneously, you have to think to all of that.
They trade on different EAs, different days, so hardly ever more than 4 trades are on at the same time.
so, under same conditions, what is best, to have 2 mt4 with 12/13 eas each or just 1 MT4 with 25 eas working. (or maybe it does not matter).
Best is that you have more options for example just one ea that does everything.
Why do there need to be 25
that's indeed the best option. with mt5 it's possible to test your money management & positions management in multisymbol mode, otherwise, you have to mind your equity by restricting the number of ea by account and the risk or by educating your ea for it to never open when freemargin is not enough.
well technically is the same EA, but I open different graphs to run this EA with different settings on every graph.
Unfortunately I don't have only one EA that does everything. Thanks
