Yes, I agree with you, but that's just a standard feature. Can we know for sure whether a broker is ECN or not?
Actually, we sometimes don't care what type of broker it is because what matters is that our money is safe, trading runs smoothly, and our withdrawals are paid. The most important thing, in my opinion, is that we know who is behind the broker so that when there is a problem, we can ask for clarification and find out their track record.
