Pharm up on good news of phase 3 migraine patch, bought near close on a dip with a plan to hold overnight. Went from 5.73 to 5.9's and back to 5.73 within 5 minutes so I sold at the same price I bought thinking it wasn't done dipping. It held at 5.5's but I didn't re-buy because I realized I couldn't trade at market open the next day. It did gap up at the open then provided a nice panic dip-buying opportunity just after open.
