It seems support is at 160, resistance @ 169. The best time to short it seems to be the pre-market, when people bid it up for some reason. Then it falls, but bounces back up when it gets near 160. So there''s a $9 gap there between HOD & LOD. Seems like a $5 gain each day is possible on in & out trades, but you have to use limit orders, because of big spreads between bid & ask.
It moves fast though, so you have to be nimble. Crazy stock. I'm still expecting a $20 drop one of these days, as insiders are dumping like crazy, and from lower levels.
