Hey all,

I just want to check if I'm thinking correct, doing paper trading and trying to get a few concepts to stick.

I put on a trade in USO yesterday, which at the moment of my trade was trading at 19 and a bit. I've put on what I belive is a call spread (???). I sold the april 20 call and bought the april 21 call hoping the stock stays where it is or goes down or not up to much. Am i correct here?

Now in my monitor tab i am plus minus zero on the trade. The 20 call i sold is up $20 and the 21 call i bought is down $20. Im not really sure why the two move in different directions though?

All advice is much appreciated!
