Trading is a great business. One of the main benefits is that you don't have to work crazy long hours (unless you really want to). We do though suggest if you want to day trade you set aside at least the first hour of the day - preferably consider an hour before market open and the first hour of the morning session as "hours I really should be at my screen". The rest of the day is optional.
That's what we do here at Inteligex. As an International company though we do that for the European session as well as the USA session. It delivers great profits almost every day - today being no exception with $860 in 3 trades - which included one weird $20 loss with a real "fat finger" trade.
