Spread is very important for online traders, as it reflects the difference between the ‘Sell’ and ‘Buy’ rates of every CFD instrument. For example, if Amazon shares are traded at 1,580.50 / 1,580.58, you can sell a share for 1,580.50 or buy it for 1,580.58. In this example, the spread is exactly 8 pips (in this case, 8 cents).
