We got a nice rejection near the first level of resistance (I mentioned it in previous SP500 analysis). Sellers entered with good volume, but the trendline is still holding!! Likely there will be attempt to break it. There is a possibility to retest 2 important zones before this attempt - previous swing failure and yesterday's top (to form double top). Don't hurry with shorts, let this market do its thing, and form strong signal. One day with sell-off is not enough
