Playing this pullback in WFM

Today I jumped in a WFM Sept 38/37 put spread. I picked up a $130 credit on 10 contracts. 

This stock has been STUCK in the mud for weeks now. It can't seem to break and sustain anything over $39.70, but it's also built a solid base. The 20 day EMA is right at $38.78, also $38.50 looks like good support. Of course anything can happen, but I think all the bad news has washed out of this stock and we head higher from this area.
