At present I am trying to educate myself regarding stockmarket.I am looking at etf's.I notice that some of these are listed on London and Newyork stock exchanges and priced in pounds and dollars.Which currency is the correct one,does it depend on where the fund is held,in the case I am looking at it is held in Dublin(ishares),does it matter which currency you buy in,if you are starting with euros and hopefully when sold converting back to euros?
