Fear – Traders become fearful of entering the market usually when they are new to trading and have not yet mastered an effective trading strategy like price action trading (in which case they should not be trading real money yet anyways). Fear can also arise in a trader after they hit a series of losing trades or after suffering a loss larger than what they are emotionally capable of absorbing. To conquer fear of the market, you primarily have to make sure you are never risking more money than you are totally OK with losing on a trade. If you are totally OK with losing the amount of money you have at risk, there is nothing to fear. Fear can be a very limiting emotion to a trader because it can make them miss out on good trading opportunities.
One unique aspect of this international market is that there is no central marketplace for foreign exchange. Rather, currency trading is conducted electronically over-the-counter (OTC), which means that all transactions occur via computer networks between traders around the world, rather than on one centralized exchange. The market is open 24 hours a day, five and a half days a week, and currencies are traded worldwide in the major financial centers of London, New York, Tokyo, Zurich, Frankfurt, Hong Kong, Singapore, Paris and Sydney—across almost every time zone. This means that when the trading day in the U.S. ends, the forex market begins anew in Tokyo and Hong Kong. As such, the forex market can be extremely active any time of the day, with price quotes changing constantly.
You need to always manage your risk properly. If you do not control your risk on EVERY single trade, you open the door for emotional trading to take hold of your mind, and I can promise you that once you start down the slippery slope of emotional Forex trading, it CAN be very hard to stop your slide, or even recognize that you are trading emotionally in the first place. You can largely eliminate the possibility of becoming an overly-emotional trader by only risking an amount of money per trade that you are 100% OK with losing. You should EXPECT TO LOSE on any given trade, that way you are always aware of the very real possibility of it actually happening.
Factors like interest rates, trade flows, tourism, economic strength, and geopolitical risk affect supply and demand for currencies, which creates daily volatility in the forex markets. An opportunity exists to profit from changes that may increase or reduce one currency's value compared to another. A forecast that one currency will weaken is essentially the same as assuming that the other currency in the pair will strengthen because currencies are traded as pairs.
