The trading of stocks and shares is predominately conducted through centralised exchanges, which means that the price at which securities can be bought and sold, is controlled and manipulated by a few dominant institutions. There is, therefore, little opportunity to seek a range of prices for buying and selling within the market place. The Forex market, however, operates using a distinctly decentralised structure. Many institutions and organisations can offer currency transactions at a variety of different prices. This means that there is the opportunity for a variety of quotations amongst dealers and the chance to buy and sell at a range of prices. This type of decentralised organisation can initially seem confusing, however, by its nature, it actually provides considerable opportunity for retail traders. The competition that exists between institutions and market players actually ensures that the best possible pricing deals are available all of the time.
