After I did my woeful post earlier this morning, tagging it with a "Defeat" category, I decided to do a little experiment.
I used the category cloud to see all the posts I had done with a Victory, then I looked at all the ones that were marked as Defeat. I've put a chart of the S&P below with the times that I did a "defeat" post marked in yellow and the time I did a "Victory" post marked in green.
Notice a trend here? When I'm feeling on top of the world, the trend changes against me; and when I'm feeling dejected, I should short like mad.
I guess the Emotional Awareness note on my rules page is quite true.
