The difference of the Forex and stock market is in the levels of access that is the integral part of the Forex market. The highest level is designed for the inter-bank market (the participants are large banks). The bid/ask spreads of this level are commonly not available to those traders outside this level. There is a certain trend, the lower the level of access the bigger the bid/ask spread (it can vary from 0-1 to 1-2 pips for most traded currencies). The main factor determining the amount of the spread is the volume.
