I trade on an ECN account with the broker. I decided to open it as soon as I learned that their ECN account is commission-free. That was something new for me because as a rule most brokers charge commission for tight spreads on their ECN accounts. Well, on one hand, this broker’s offer seems very generous, but over time I learned that there’s one restriction. The broker doesn’t allow to hold a trade for less than a minute. Technically, you can do this but if you earn money for less than a minute, the broker will take your profit. When I started to scalp on the broker’s ECN account, that restriction was an unpleasant thing for me, but overtime I got used to it and learned to scalp differently.
