I'm just beggining to research the forex market and how I can use it to help hedge commodity positions. But I have a question regarding multi-leg positions. For example: If I sell the EUR/USD spread and at the same time sell the USD/CHF spread how can I quantify the difference between that and selling the EUR/CHF spread. It seems to me that the only practical difference is the dirrectness of the relationship. I'd appreciate any insight into this that could be offered. Thank you.
