Etrade will let you for instance sell x stock and buy y stock immediately. If you sell the y stock before the 3 days on x is up, then 90 days in prison. I really didn't expect PTEN to dip that hard today. I need to start letting the $ sit for 3 days after a sell as a rule!
Emotion does factor in for sure.lol I even got some action out of my BLDR today. Thought it had actually grown roots.
