US Dollar is trying to gain some ground against Frank but some key resistances may have a say in that. The downtrend that started in May is still in effect and currently at 0.8975. If the price able to break the short-term resistance 0.8920, this trend line may be tested again. But just above that trend, another important resistance, a medium-term horizontal level of 0.90 can support the USDCHF bears. As long as 0.90 holds, upward moves can create selling opportunities.
