That's completely up to you and your trading style. I mostly look for progression of levels of support either lost or gained as entry and exit points. The momo on this thing is pretty sick to the upside, so the distribution process will take a while. I expect this thing will probably be ranged bound in a sideways holding pattern. A close below 100 is probably a safer entry. Anything above that offers potential of making a new high first. Completely up to you.
To be completely honest, I don't even use volume on my charts. If you look in the description you will see I said this is probably due to the split. But if you look at 09/08 volume candle, you will see how it was much higher, and resulted in very little progression. This is a bearish signal.
