A computer with a reliable, high-speed connection to the Internet, a small grubstake, and the information in this book are all that are needed to begin trading currencies. These are the tools of the trade in retail FOREX. Patience can also be a virtue; something the fast-paced currency-trading world does not particularly foster.
You do not even need the grubstake to practice; a free demo account is offered by all retail FOREX brokers. In fact, I encourage you to open at least one demo account early in this book and use it as a learning tool before committing real funds to the market.
