Trading: I sold $FIO and kept $FIVE

$FIO - I sold my shares today.  The first half for $16.50 and the other half for $16.30.  I held this stock too long and took a big loss.  I can't keep repeating this mistake.

$FIVE - Yesterday my stop loss triggered at $40.50 and I sold my shares.  Later in the day I repurchased those shares for $41.08.  The rebound in the stock indicated that the pull back wasn't severe and it reversed.  The 50 day moving average is serving as support as well as Volume Profile.
