Hi there , i am doing very well on my demo account and am going to sign up for my real spread bet account . How long can i keep a position open for ? I have a Bitcoin position open on my demo and the price has fallen since i predicted it would rise . How long on a real account can i keep this position open for because as soon as it goes above what i paid , i will close it and be in profit . Are there any fees the longer it stays open ?
