To do forex business it is necessary to have an account with a forex broker. Because forex broker execute the whole trading process through their trading platform. They work as a middleman for traders. So, you are thinking that why broker will do so for us. Basically trader make profit from charging commission to trader. This charge they keep from the spreads. So, those broker are always good who provides lowest trading spreads. I am trading with TopFX24, which is a lowest spreads provider.
