The USD/JPY bulls made a massive power play in today’s session, but the momentum has hit a significant wall. While the morning was defined by aggressive buying, the failure to sustain the breakout has handed the "short-term steering wheel" back to the sellers.The Rise: Clearing the 100-Hour MA and Last Week’s HighThe day began with a decisive move away from the 100-hour moving average, as buyers successfully cleared the previous week’s high of 156.826. This surge appeared to have legs as it charged toward two major technical hurdles:The February 9 High: 157.65A Major Topside Trendline: Intersecting near the same 157.65 level.For a moment, it looked like a clean break. The pair pushed to a session high of 157.75, briefly signaling a new regime of Yen weakness. However, that strength failed.The Reversal: "The Buyers Had Their Shot"The bulls had the opportunity to turn 157.65 into a floor, but they missed. The price has since collapsed back below both the February high and the broken trendline.In technical terms, this is a failed breakout, which often leads to a fast move in the opposite direction. By failing to hold the extension, the buyers have lost their immediate grip on the market.What’s Next: The Seller’s Road MapThe burden of proof has now shifted back to the buyers. Until they can reclaim and close above 157.65, the sellers are in the driver's seat for a corrective rotation.Immediate Target: A move back toward the previous high-turned-support at 156.826.Secondary Target: If 156.826 fails to hold, expect a deeper rotation down toward the rising 100-hour moving average.The Bottom LineThe "rejection" at 157.75 is a warning sign. Sellers have proven they can take down the buyers' momentum at a critical resistance junction. Unless the bulls can muster a quick recovery above the February high, the path of least resistance points back toward the moving average.
