Any form of currency trading will require a computer with a decent broadband connection as you will be streaming a lot of data. Access to the Forex market is usually provided by brokers through their own online trading platform or downloadable software.
Many online brokers will also offer you the opportunity to open a virtual account for at least a couple of weeks before you start trading with real money. This is a great way of familiarising yourself with the foreign exchange market without having to incur the losses you may encounter through your own inexperience with a 'live' account.
Knowledge is key when trading foreign currencies and you should take the opportunity afforded by your virtual account to study how different pairs of currencies behave over a period of time and how they behave in relation to each other. While you are still learning the intricacies of the market, it might also be a good idea to stick with just one currency pair and then expand as your confidence grows.
Staying in touch with what is happening in the world through the regular news agencies is always a good idea as knowledge of what might cause a currency to rise or fall (like government debt, economic growth or inflation rises) is always useful. Things like a basic knowledge of commodity markets can also be of value as fluctuations in the price of commodities like gold or oil can also be a factor in affecting currency.
Many Forex brokers offer access to live news feeds to all account holders and this is something to look for when you're choosing a broker and an account. These news feeds are well worth taking advantage of as the information they include is likely to be both relevant to, and influential on the movement of currency in the Forex market and therefore your buy and sell decisions.
