I saw this http://paststat.com/blog/spy-gained-for-3-or-more-days-in-row-on-a-friday-during-the-medium-term-downtrend-very-bearish/

Basically,  3 up days including today and today is Friday and Close is less than 50 days simple moving average. If I add a filter saying that today’s close is in the upper half of today’s range, (a little over bought), the winning percentage goes to 100 with 22 trades, 23rd trade is our open trade now triggered Friday 9/6/2013.
