Just like my mate the Euroyen, ED is just about done as a buy side winner (unless you think 3mth libor will become negative).
Z3 hit 99.00, only 100 points to go and then what? In fact, there must be a price 99.00>X<99.99 where long term trend traders will not follow buy orders. For my system, the initial risk in points on ED is between 25 and 50, depending on volatility.
On a related matter, in 2001 I knew a fellow that sold Euryen at 99.90 on the theory that he had only 10bps max loss. He held that position for the whole year. Didn't go far.
