Frequency and costs: A novice scalper has to make sure to keep costs in mind while making trades. Scalping involves numerous trades — as many as hundreds during a trading session. Frequent buying and selling is bound to be costly in terms of commissions, which can shrink the profit. This makes it crucial to choose the right online broker. The broker should not only provide requisites like direct access to markets, but also competitive commissions. And remember, not all brokers allow scalping.
