Short US30- fibb approach

I am using an analysis on US 30 for each direction. I have placed a fibb on the previous low and the current higher high. I will look to short when candles breakout of the 78.6fib and act as resistance to the 9ema for over a 100 pip target closing trade at the 61.8 fibb level at shoulder level. Watch for the double top near the demand zone on 15 min tf.
