Operated by Russian fellas? Do not trust to them, better to choose something more trustworthy from UK like tickmill or oanda, IMO
Still, they haven't cheat me and everything I earned has been withdrawn. An average market maker. But all of them are mm's in some way. I believe that ECN-schemes work somehow.
And if talking about some serious company as Interactive brokers that is surely not a marketmaker, I'm not ready to depo $50K, but hope I will be able to do that someday!
