Hi, does the spread between Spot Fx and it's corresponding futures narrow as expiration draws close? For example, if I long EURO spot and short EURO futures at the same time, will their values always come closer or farther apart as expiration date draws nearer? How does interest rate affect this spread? How do you rollover a currency or index futures without realizing your loss? Simply closing current contract and re-buying the farther contract means cutting loss such that you may not be allowed to keep the same number of contracts. Does buying a spread in the farther contract automatically rollover your expirating contract without locking in your losses?
