what is the spread in a forex 
the forex spread is the bid price subtracted from the ask price of a currency pair for example if eur usd has an ask price of 1 1053 and a bid price of 1 1051 then the spread is 0 0002 or 2 pips to calculate the cost of the forex spread you need to multiply the spread by the trade size or volume for example if you trade 100 000 units of eur usd with a 2 pip spread then the cost of the spread is 20 00 0 0002 x 100 000
