The S&P is moving in an uptrend for the last days and weeks. I think this formation shows good that the trend will continue after a pullback.
The neckline of this formation is also at the 38.2 fib level of the last upside move. So I expect a short term price fall back to 2083 +/-. And then the price should go up to an area around 2115-2120.
I will open a trade now with a tight stop loss below the last low under the neckline.
Target is around 2110-2120. Will see how it works.
Just to mention it, this is no edvice to anyone to do as I do. Do your own analysis and decide if you want to take a trade or not. This is just my opinion.
