As an avid trader XM was the most rational choice for me. I work with multiple assets, but target ones are precious metals and currencies, ofc. AUD/CAD, USD/JPY are those in my "daily goals" list. Spreads are favorable, sometimes they wave around 1.5-3 pips which is appropriate. Leaving position open overnight isn't a biggie either, swaps don't bite, so that's why I opt for XM.
