Switching a brokerage is always a challenge and for me that was a challenge x2, as my prev. Brokerage offered extremely tasty bonus and loyalty programms. However, the thing was that my prev. Brokerage was unregulated and I was looking for sth more stable and remarkable (lol). I started with my prev. Brokerage (sry for not calling it's brand, don't think that's ethic) with $100 and when you're trading with such pennies, that's not a problem that your brokerage is registered on SVG. But if you're trading with $50,000, that's a challenge for real. It just eating your mind, all this thoughts about 'what if I would be scammed.
And that's a Big reason to switch brokerage.
Trading conditions in FxPro are almost the same (if we don't take in account bonus programm of my prev. Brokerage), but it's regulated =)
