[MENTION=75]Cutiekc[/MENTION] that's a good point on why some brokers don't alot scalping; actually reasoning that the scalpers are cheating them by risking little and earning more. Until now, I was thinking that it was only as a result of server overload that some brokers don't allow scalping.
Yes, that is the only reason that many brokers don't allow scalping. Scalping can be done frequently and anybody can earn a good amount with low risk.
