Forex Strategy 10: Low Risk/High Return Currency Trading
This isn't a book with a set of rules for a trading strategy. The book doesn't tell you where to buy or where to sell the EUR/USD or any other currency pair. If you're looking for a book about specific tactical setups for trading - then there are many, many good books available.
What this book does is attempt to set your expectations at a more realistic level from the very start. It's a book about perspective. And a right perspective from the start is essential.
