HQ Level is the number to the right of your name (where it says Level. ___). It determines what difficulty level you can do for this event.

Also, when you say win/loss ratio, you are referring to the sortie win/loss ratio, correct? At least 75% sortie win/loss ratio is required for an event.

Finally, I'm guessing you already chose easy mode and can't switch to a different difficulty level (since you appear to be under level 35, and can't choose medium). Otherwise, perhaps there's another requirement you don't meet.
