These are my thoughts on PRTY. They are meant to give you an idea, not trading advice.
Party City is very low at these levels.
It looks like this stock is about to start building the right shoulder, to form an inverted Head and Shoulders pattern, which according to the textbooks is bullish.
If this is so, a buy at the lows of the forming shoulder would be a very good buy to enter a long position.
There's a gap at the end of 2019 that could get filled, what should take the price to about 5$.
