The USDJPY made a moderate bullish momentum yesterday, topped at 90.36 and closed at 90.13. On h4 chart below we can see that the hammer formation still provide a potential threat to the bearish outlook. Will it trigger a bullish reversal or just a correction? For me, the key area is the 90.20 and trendline resistance (blue). A Breakout to the upside from that area could potentially be a bullish reversal signal at least targeting 91.40 area. Immediate support at 89.50 area.
