AUDJPY Recap - Why I short in the face of an Uptrend

OANDA:AUDJPY   Australian Dollar / Japanese Yen
Was anticipating a run on sell stops at current weekly low based on the weekly close above the last down bar's 50% (So often a retrace occurs).
Price DID come to my alert to take some profit, of which I was asleep. Closed trade before full stop out and went long.
