USD/JPY 30m Chart reversal

OANDA:USDJPY   U.S. Dollar / Japanese Yen
Possible reversal of trend on the 30m chart of USD/JPY . Trend lines moving bearish in general and tested the support of the bottom trendline. Previous pattern shows possible head and shoulders pattern, also possibly indicating a trend reversal.
Looks to be a possible short on a bullish rally as part of this.
