Buying rule #1, wait until 10:15am

1/28 was a sell signal.  Next trading day 1/31 the futures were up and the market was up by 10:15am.  This means the sell signal was canceled and hold the long position.  Always wait until 10:15am to see were the markets is going so that you do not blindly trade at the open.  This rule is to avoid being whipped....
