Watching $X at 54.84 – is this resistance holding?

I'm keeping an eye on $X here at 54.84. We've seen it bounce off this area a few times now, and it's starting to look like a pretty defined ceiling. If we get a sustained break above 55.00, especially on decent volume, my current short-term bearish bias would be well and truly invalidated. Otherwise, I'm expecting some kind of pullback from here.
