Today there's an exclamation point after wave "IV" because it bottomed in between two Fib support areas.
The brown line at 2651.46 = .50 of wave "II".
The blue line at 53.76 = .382 of wave "III".
Upside target for today remains 2675-2678.
When I did the post just before the open 12/15, the SP futures were already up several points. Many people on this site may not see this post until later in the day.
From a risk/reward point of view its better to wait and see if the SPX can reach 2675.
If shorts can be entered at that zone there is a good chance to catch 60 to 70 SPX points on the downside in the next 3 to 5 trading days.
This is better than scraping up a few upside points on an SPX day trade.
I will have an update on the SPX 12/16/17
