HOW TO CHOOSE A BROKER The forex broker that you use can significantly affect your trading success. There are two types of forex brokers: market makers and ECNs. But in practice things are not so clear-cut – there are market makers out there who falsely market themselves as not having dealing desks, while there are also some brokers who claim to be true ECNs when they are not. The choice of broker must be an individual decision, because everyone has different needs and preferences. Both new and existing traders should carefully examine the practices and policy contracts of brokers, and be up-to-date with new information on brokers. Below are some points that you might want to consider when selecting a broker. You can use it as a rough guide to narrow down some candidates that match your own needs.

Forex Trading Is A Serious Business Forex trading must be seen as a serious business, not just a casual roll of the dice or a leisurely pursuit. If you approach trading as a means of getting your dose of adrenaline, do yourself a favour by staying away from it . Serious money demands serious work. Winners from the trading arena take a nononsense approach to trading – they take care of their P&L (profits and losses), enter only into high probability trades and keep meticulous record of all their trades. Both serious and casual traders, of course, dream of making it big in the forex market, but it is not the goal that counts, it is the preparation and dedication that is important. Forex trading should be considered and treated as a serious business, just like other types of businesses. Approaching trading from the perspective of a shrewd business person can greatly tilt your chances of success to your side.
RISK DISCLOUSURE Trading forex involves substantial risk, and there is always the potential for loss. Your trading results may vary. No representation is made that any information in this book will guarantee profits or prevent losses from trading forex. You should be aware that no trading strategy can guarantee profits.
MARKET SENTIMENT The forex market is heavily driven by market sentiment, and it is market sentiment that influences traders’ decisions by triggering certain emotions and thoughts. Find out what defines the current market sentiment, and how you can incorporate market sentiment analysis into your trading.
