There are a number of different ways to trade currencies, all of which are detailed on forex news and tutorial sites. The two most common ways of trading Forex are futures and spot, the main difference between the two being the amount of time that passes between the agreement to trade and the actual exchange taking place.
A futures agreement is a legally binding contract between the two parties to exchange currencies at a pre-arranged rate at some point in the future. This may seem like a boring way of playing the Forex market, but investors can make huge profits if the currency they have agreed to trade falls in price in the meantime. By buying up more of the currency at its cheaper price and selling it on at the legally binding higher value, investors can make a great deal of money. You can make the exchange before the agreed date, if the two parties agree; this is what usually happens, rather than both waiting until the closure of the contract, which can sometimes be several months down the line.
Spot deals are those which are agreed in the short-term, with the exchange taking place just two days after the agreement is reached between the two parties. The only exception is trading between US and Canadian dollars, in which case the exchange happens the next business day. This is ideal for those who wish to take advantage of a sudden change in the value of a currency, which would allow them to make an unexpected profit. It is also the most popular type of trading among amateur investors, thank to the immediacy of the deals; rather than having to wait months for something to happen, investors can easily make spot trades online through their broker.
