Relative Success with TLT (knock on wood) and USO trade

My TLT vertical is up a decently, initial credit was 0.53 and now its at 0.35, so not bad. Today's big up move may continue into the end of the week and IV may drop as well, both good for my position.

I also traded an iron condor in USO, an oil company. It's up better than 4% today and it's IV has remained elevated due to the fluctuations in crude oil. I'm getting a little bit closer to the market than I normally would, but the credit for further OTM options just doesn't justify the risk.

I'm taking a little less risk with the USO trade than with TLT because it has a much lower PoP. TLT had a 71% at inception, and the USO position, a May 1st 15/16/19/20 iron condor has a 52% PoP.

Why so close to the market? USO has resistance at 19ish and support at 16ish, so it's likely to turn around once it gets close to those strikes.

I've sold 10 of them, risking a max $600 and gaining a max of $400. (cr = 0.40)
