As long as the 0.8928/0.8918 levels continue to hold as support, our bias on USD-CHF will remain to the upside. The 0.9180 level will be the next upside target. A breach of that level will allow for further strength toward 0.9292, the dollar-Swiss franc's April 6 high. > > Bull or Bear? Vote in Our Poll Further out, resistance stands at 0.9340, the April 1 high, and then 0.9400. Alternatively, support comes in at the 0.8928/0.8918 levels, USD-CHF's Sept. 12 high/Sept. 29 low, where a reversal of roles as support is expected to occur. If that level failed, however, further weakness could develop toward the dollar-Swiss franc's Sept. 15 low at 0.8647. A break through that level would pave the way for a move lower toward 0.8574, the pair's Sept. 8 low. All in all, USD-CHF remains biased to the upside.
