there's a market top around here somewhere (here or higher). if you're not watching S&P you shouldn't be playing this. sounds like you need to adjust your strategy. if you bought at 3.05s and it ran to 3.50s then you just didn't take your gains. and then you let a winner turn into a loser.
I held all my 2.94-2.96's and still trust the chart. IMo you shouldn't sell as the S&P is starting to show weakness. See if the daily pattern develops to the downside, so far this is day 3 in a row the S&P couldn't run.
