Good for you. Change things up from time to time. Try something a bit different. See what works for you.
I read somewhere to cut your losses short, and let your gainers run long. I try to emulate this.
By today's UGAZ chart, you are up ~35% today alone. You could place a stop loss 10% or 20% underneath this, and know that you have locked in a gain of some sort, then sit back and watch the week play out. Setting a stop loss might help you sleep better tonight.
Just a thought.
Also, you have likely seen the Lionel Richie commercials for TD Ameritrade about trading 'All Night Long'. I can choose to set a stop limit that is in effect 'after hours' too. Effectively 24 hour protection. I don't know about Fidelity after hours trading, but if they have something similar, you might want to consider it for peace of mind overnight.
GLTY!
