Why 2525 is a definitive trend requirement.
The 3 day pattern is an attempt at a reversal. You have a middle lower low than either day before or after forming the triangle. If it fails its generally signaling further decline. The day 3 pattern is the key. See the last one that had the bottom triangle but the 3rd day failed to reach close to the 1st day high. I call that a Bear Wink signal and hedge accordingly into the close.
This current 3 day attempt has come all the way back and eclipsed the 1st day of the triangle. a close above 2518 would be extremely bullish and I wouldn't hedge anything. A close above 2500 would be bullish but I would hedge. All this against the backdrop of getting fills at targets on % of stocks bought on the 2350 bottom and those entered yesterday like FMC or re-entered sales made from 2350 such as SQ and V rebuys, along with selling naked Puts on stocks like AAPL.
Buy low/sell high!
also note we have a cup and handle from the 2350 forming.
