I did this to one guy just to show how to use trendlines and channels to take positions and set SL's etc.. But I think its also as good as it gets for SPX next week.
Shorting above red when it crosses flag area down.
Longing now and reversing either on the RED line, or above it when it starts go come down again. On second scnario it will need to start going down on tuesday, and penetrate that cross down.
