Multiple are converging right at the moment of New Years (before midnight west coast, just after the ball drops on the east coast). The @24.0, caused by repeated attempts on a 20-30K ask wall, now simply needs a new push, as the wall was bought up completely in one order during the last pullback, and shouldn't provide resistance this time.
The positioning of the huge ask wall and multiple buffer walls before it at 23.8 and 23.9, together with coordinated selloffs to push back after the wall was neared, demonstrated a not-so-subtle attempt to suppress the slow rise from breaking out "ahead of schedule". The filling of that $1millionUSD+ order, however, had absolutely no effect on BTC-e price action or , oddly enough. Even OKcoin started a rally at the sight of that massive buy, but quickly fizzled when it became obvious that BTC-e wasn't inclined to react at all, in fact slumping afterwards.
