There are actually three ways that institutions, corporations and individuals trade forex: the spot market, the forwards market, and the futures market. Forex trading in the spot market has always been the largest market because it is the "underlying" real asset that the forwards and futures markets are based on. In the past, the futures market was the most popular venue for traders because it was available to individual investors for a longer period of time. However, with the advent of electronic trading and numerous forex brokers, the spot market has witnessed a huge surge in activity and now surpasses the futures market as the preferred trading market for individual investors and speculators. When people refer to the forex market, they usually are referring to the spot market. The forwards and futures markets tend to be more popular with companies that need to hedge their foreign exchange risks out to a specific date in the future.
You have probably heard that most people who attempt Forex trading end up losing money. There’s a good reason for this, and the reason is primarily that most people think about trading in the wrong light. Most people come into the markets with unrealistic expectations, such as thinking they are going to quit their jobs after a month of trading or thinking they are going to turn $1,000 into $100,000 in a few months. These unrealistic expectations work to foster an account-destroying trading mindset in most traders because they feel too much pressure or “need” to make money in the markets. When you begin trading with this “need” or pressure to make money, you enviably end up trading emotionally, which is the fastest way to lose your money.
The problem is that this is where traders are most likely to succumb to overconfidence bias. It's not uncommon for traders to complete a winning streak and then believe that they can't get anything wrong in the future. To believe this is of course unwise, and is only going to end in failure. Make sure you always analyse your trading sessions and look at your wins and losses in detail.
