I'd give it 25 or near 25. If you missed it, don't chase it.
I think the most important "technical" reason for that bounce on facebook was the 61.8fib retracement.
If you take the lows of September 2012 and connect them with the highs around late jan 2013 you could see that the 61.8 fib was at ~23.26.
However,if the tape starts weakening i don't think facebook has any chance in fighting a weak tape.It will break the fib,moving averages etc.
