Scalping is a type of trading in which your positions are opened and closed with small time frames that can range from a couple minutes to a couple hours. Scalping orders are placed many times a day and are meant to capture smaller price moves in the Forex market. There are many brokers that accept scalping. The brokers that make their money off pip spreads only are the brokers that don't care if you scalp. Scalping actually makes them more money. If a broker doesn't allow scalping then they are a market maker.
