The Gann Rules for a real CIT (Change in Trend) to down is the decline should last longer than 2 TD and must exceed the largest decline which was that 26 SPX points.
So far the SPX has surpassed the 2 TD and 26 point RULE which means the trend has officially turned to down and you should no longer heavily buy dips, but instead sell rallies.
Bottom line is I plan to AGGRESSIVELY short any rally that appears next week based on the Gann trend and my X-wave count.
