Mistaken trade amplifies losses

AMD, not necessarily my setup in the first place, so big smack in the face for that. AMD gapping up with NVDA which was way up on earnings. However both gapping into resistance, so I looked to fade. 

First puts stopped. When it reversed off the top, I tried for new puts, but accidentally bought calls. By the time I realized why I wasn't raking it in, I was down pretty bad and cut it. Tried to find a new entry for the puts I really wanted, but I missed the boat for another loss, instead of nice gain I would have had off the top. <grumble>
