2. How do Currency Markets Work?

Unlike shares or commodities, forex trading does not take place on exchanges but directly between two parties, in an over-the-counter (OTC) market. The forex market is run by a global network of banks, spread across four major forex trading centres in different time zones: London, New York, Sydney and Tokyo. Because there is no central location, you can trade forex 24 hours a day.
There are three different types of forex market :
Spot forex market :
The physical exchange of a currency pair, which takes place at the exact point the trade is settled – ie ‘on the spot’ – or within a short period of time
Forward forex market :
A contract is agreed to buy or sell a set amount of a currency at a specified price, to be settled at a set date in the future or within a range of future dates
Future forex market :
A contract is agreed to buy or sell a set amount of a given currency at a set price and date in the future. Unlike forwards, a futures contract is legally binding
Most traders speculating on forex prices will not plan to take delivery of the currency itself; instead they make exchange rate predictions to take advantage of price movements in the market.
