The 2nd method is by performing a carry trade, where you can profit by buying a currency with a higher interest rate, and selling a currency with a lower interest rate. An example of this would be the USD/CHF (Swiss franc). If you buy USD/CHF, you are buying the USD, and their interest rates are higher than Swiss interest rates, so if you hold the position overnight, every day you hold the trade you will make money, and the money will be deposited in your brokerage account.
I would be lying to you if I said that success in the Forex markets depends entirely on the system or strategy you use, because it doesn’t, it actually depends mostly on your mindset and on how you think about and react to the markets. However, most Forex websites trying to sell some indicator or robot-based trading system won’t tell you this, because they want you to believe that you can make money in the markets simply by buying their trading product. I prefer to tell people the truth, and the truth is that having an effective and non-confusing trading strategy is very important, but it’s only one piece of the pie. The bigger portion of the pie is managing your trades correctly and managing your emotions correctly, if you do not do these two things you will never make money in the markets over the long-term.
Most retail investors should spend time investigating a forex dealer to find out whether it is regulated in the U.S. or the U.K. (dealers in the U.S. and U.K. have more oversight) or in a country with lax rules and oversight. It is also a good idea to find out what kind of account protections are available in case of a market crisis, or if a dealer becomes insolvent.
More specifically, the spot market is where currencies are bought and sold according to the current price. That price, determined by supply and demand, is a reflection of many things, including current interest rates, economic performance, sentiment towards ongoing political situations (both locally and internationally), as well as the perception of the future performance of one currency against another. When a deal is finalized, this is known as a "spot deal." It is a bilateral transaction by which one party delivers an agreed-upon currency amount to the counter party and receives a specified amount of another currency at the agreed-upon exchange rate value. After a position is closed, the settlement is in cash. Although the spot market is commonly known as one that deals with transactions in the present (rather than the future), these trades actually take two days for settlement.
