Of course when Forex first began the Internet was a distant dream and therefore trading was carried out exclusively by the cash rich worldwide organizations.
These were companies who could afford to throw a few million in to the mix in an attempt to make some big money trading currencies.
Trading was carried out over the telephone via several exchange centers all over the world. A trader would monitor global activity and then ring their broker in order to commence or complete a trade order.
The transfer of funds to complete trades was done through bank transfers which often took a few days to go through. This meant that whilst the Forex market offered a fantastic earning opportunity, trading was both time consuming and a hassle.
With the advent and then increasing popularity of the Internet, Forex trading online opened up the doors to millions of people who had never previously had the resources to take part.
Gone are the days of having to phone through your intended trade, Credit and Debit cards are even accepted with some online brokers for depositing funds. Even more recently the Forex market has opened up to individual traders even with very small amounts to invest.
