The bid/ask spreads seem to be getting better. Anyone been trading 7E, 7A and so on? I'm considering using them to synthetically "change" small (10K) accounts' funding currency. For example, create the interest and FX risk that an account would have if it were denominated in Aussie though it's a USD account. Advantages over cash FX: the interest! For ex Dec Aussie is 50 points (or pips) under the cash. That's the interest payment you'll receive for holding it (futures will converge with cash until expiration). Hold 6A from now to expiration and you take $500 in interest. Broker doesn't skim (or scam) your interest payments away. Also these little guys seem nice for longer term position trades in general. As in several months at a time. Any thoughts? Still not liquid enough? Reasons to stay away?
