As far as I can tell only the euro and the jap yen have a lower spread ie looking at 1-2 on the euro and 2 on the yen atm. Also is there any place to view RT charts of these currencies? in regards to trading the DAX hmm are those only european futures?
(1) There are some retail foreign exchange trading firms that offer free RT(real-time?) charting capability. (2) Regarding the DAX, it's possible that there might be an ETF(exchange traded fund) for that index. Look around and see.
