A very uncommon topic in finance and the foreign exchange (forex) market is the notion of Swap. What does swap mean in forex?
Swap is a type of agreement typically between two foreign entities designed to obtain loans using the currency of the other party's country and then swapping the interest cost on the loan between both parties.
This process involves the buying and selling of an equal volume of two different foreign currencies simultaneously with an initial swap at an entry or spot price and then a final (exit swap) at a forward price.
