I just look at it and think about what's happening in the world and with the market that day. I only sold today because the DOW was gaining strength yet TVIX was holding over 20 well and I felt it would go below 18 if the markets didn't head down but it has touched barely below 16 on the past two pullbacks in the AH after hours but I usually jumped on before that as it can open 2 bucks up or down. It's an exciting play that is trading with HUGE volume. Almost 38 mil today with only 31.3 million shares according to my TDA. We've had more volume in two weeks than the 6 months before that I'd bet. I don't have triggers as much as I watch how much % it's moved and realize there are a lot of peeps daytrading it. Also do the opposite of Stock Split when they buy get ready to sell when they sell get ready to buy. (LOL) It's sad to see someone on the wrong side of most of those trades. At least they are learning and not going 'all in' in the first purchase. Good luck PAK :-D
