Anyone here trade the Nikkei from the US? Do you trade the Osaka or Singapore exchange? I am thinking about trading the Nikkei (Singapore) through IB. I have never traded in foreign markets before and was wondering if there are things that I need to be aware of, like impact on tax reporting, currency conversion, etc. Also, Singapore exchange has two Nikkei contracts: one with USD margin and the other in JPY. Which one is better?
