The USD/CHF rally has finally "come off the boil" following two days of aggressive, war-driven safe-haven buying. After a sharp breakout above its recent trading range and the 50% retracement level (0.78206), the pair surged toward the 61.8% retracement at 0.78726. However, that momentum stalled at a high of 0.7878, leading to a rotation back down and a daily close below the key 50% midpoint.Intraday Action: Sellers Defending the HighsDuring today’s Asian session, buyers attempted to reclaim the 50% level, but the effort lacked conviction. This failed recovery sent the price toward a critical support zone between 0.7784 and 0.7793. While buyers successfully defended this swing area twice today, their subsequent rallies have been capped by that same 0.78206 ceiling.The Technical Battle LinesThe market is currently locked in a clear technical stalemate:The Bullish Case: To regain control, buyers must break and hold above the 50% retracement at 0.78208. Sustaining price action above this level would likely shake out short-sellers and signal a move back toward recent highs.The Bearish Case: If the support zone at 0.7784 – 0.7793 finally gives way, the focus shifts lower. Sellers will then target the 100 and 200-hour moving averages, which currently sit between 0.7752 and 0.7765. Move below those levels increases the bearish bias.In the video above, I dive deeper into these levels, showing you exactly where the "line in the sand" is drawn and why these zones are dictating the current price action.
