Ultra low account seems the most reasonable for positional trading. I have no idea how Xm did that but no swap fees is a very unique thing to have on the forex market.
I tried to find such a broker for a long time because at one point I realized that I spend a lot of profit on overnight fees. I usually hold positions for several days and some forex pairs have too high overnight commissions.
Not all XM instruments are swap free though, just something to keep in mind.
