$LAB is definitely bullish now, can't go short. It's best to ride the trend and chase a long position first. At least wait for 16.50 to short. Open the first position at 17.80, consider opening a second position as it climbs. Hitting 20 is out of the question. Tomorrow's weekly candle is sure to drop significantly; just a matter of whether it drops straight away or first pumps before dropping. Anyway, if the liquidation price is in the 20s and there are no crazy fees, it shouldn't be a big issue.
