As I may have pointed out in that earlier post, FXE is not ideal for this because of the nature of the expiries offered: greater than 45 DTE , you're generally left with only quarterly expiries. Generally, if you're going to ladder, you want to ladder at the beginning of each month for the next three monthly expiries out, so I had to set up a September rung and a December rung and then wait for an opportunity to fill in an October rung (and potentially a January rung at the same time) when it became available.
Then, however, we saw a resort to the Euro as a risk-off safe haven on US and European equities weakness, somewhat of a new twist in the general pattern of risk-off flight to safe haven currencies; the go-to has generally been the Yen (concern over Asian market weakness may have muted investor desire to flee there).
In light of the fact that resort to the Euro as a safe haven currency may not be transitory, I'm modifying my laddering to take advantage of bounces in the Euro (whether the result of risk-off or Greenback weakness) and will set up future short call verts largely at the 1 SD instead of at 112/115 (even though I think that is still a pretty good ).
Adding right here is, unfortunately, not ideal; I'll look for bounces in FXE back toward 112.50.
