Execution.

When I read on the website "no requotes and rejections" I thought that there would be a reduced percentage of requotes and rejections. But actually I have never seen a single requote since I started trading here. And it's been almost half a year.
No slippages either. Sure, I try to avoid trading during the high volatility times, but still my last brokerage companies were giving me slippages anyways.
So if you're:
a) scalper;
b) intraday trader;
You should definitely consider Activtrades as your forex broker.
