I didn't realise until tonight, this is a great example of a powerplay. See Mark Minervinis stuff for more info on what the basic rules are.
AXE came out of a Slightly weird base, but lifts 100%, then bases for a couple of weeks, less than 20% pullback, before a powerful breakout. I was too close to it to realise until now. But worth looking for these power play setups, because they offer very good rewards if you're sharp enough to catch them.
I use upper bollinger band breaks with OBV to identify these kinds of explosive shorter term moves. Tighter and longer the compression the better the break. This is the closest I found to be able to emulate and screen for what Mark looks for.
