SPX - Correction is confirmed

The break-down of 1495 confirms the prospected scenario a few days ago: Febraury 19 began a bearish corrective wave.
With the rebound to 78.6% Fibonacci's retracement, I discarded the idea that we were in a zig-zag pattern [a]-[b]-[c] , so in order of priority, the first two possibilities are:
> A three, single or double,  [w]-[x]-[y] + [x]-[z] (preferred count); in this case we could be in [y] wave, even if the downward acceleration of final session doesn't convince me;
> A bearish impulse wave [1]-[2]-[3]-[4]-[5] (first alternate count), that involves a deep correction (and even the hypothesis that February 19 is the top of the tops).
I stay outside.

Have a great trading day...with care!
