There is a very high probability the SPX completed an Elliott wave - Horizontal Triangle on 8/3/17. If so a post triangle trust up could be triggered by the Jobs report today 8/4/17. Post triangle thrusts are usually the widest part of the triangle added to the termination point of the triangle, which is wave "e" bottom. This targets SPX 2492 as the bulls-eye target.
If this rally occurs it could be a very significant top.
Use SPX 2486- 2494 broad target zone to short. Top could come in the first hour of SPX trading.
