If breaks through 15.4 expect retrace to 0.318 line, and then a bounce back up. However if it finds support at the 0.628 line, can expect reversal into uptrend; possibly finding resistance at previous All time high. Prime buy points would be at the 0.318 line ($13) or the 0.628 line ($16), if unsure of which; wait for trend to get close to the 0.628 support and see if 2 candles close below it back-to-back, if closes below it safe to assume will continue retrace to 0.318 support.
