Market makers sometimes offer you their own costs, based totally on the price that they expect to get on the ECN. When you open a deal they need to match it in the ECN to cover their risk. Clearly here there is room for the price to switch in the moment between you clicking the button and the deal going on to the ECN. It can imply that you don’t get the price that you expect, which can be a difficulty, especially for scalpers who are often hunting for very small profits from each trade. For that reason scalpers and market makers are not a good mix and could be unwelcome. On the positive side, market makers could be a good choice for an amateur. They will often provide good technical analysis, news alerts, a user friendly platform and a demo account.
