I don't see how the USDJPY movement will turn bearish this week. I will focus on the buying opportunity at the support at 143.20 or a trendline retest. Both would require a Magic Candle Confirmation before engaging in the trade.
If you are waiting for a counter-trend trade, the Bearish Bat Pattern on the daily chart(right) 149.12 seems like a better trading setup than the AB=CD Pattern.
