Price Improvements can help scalpers make more money than before. A scalper typically tries to gain only a few pips with each trade that they place. This means their average return per trade may be as low as 1 or2 pips. Because of this they often place tens, hundreds, or even thousands within a day. For scalpers it's the little things that matter most, and every pip counts. All price improvements are contingent upon available liquidity at execution.
