Shortie I trade through CMC markets. One can chose commission + lower leverage where one is guaranteed stops. Or just spread and higher leverage but unlimited losses in theory. For stocks i think there is always commision but not index.
how can stops be guaranteed? do you trade against the broker? what if the stock corresponding to CFD gaps down 10% overnight and you had 2% stop on your position, does it always get filled? is not brokers losing money in this case?
I don´t know. They take the risk if the client pay for it perhaps. I think that is what they mean but i use the "unlimited losses"-account.
