USDCHF stays in a falling price channel on 4-hour chart. As long as the channel resistance holds, another fall towards 1.0400 is still possible and a break below 1.0506 could signal resumption of downtrend. However, a clear break above the channel resistance could indicate that the fall from 1.0898 has completed at 1.0506 already, then the following uptrend could bring price to 1.0800-1.0900 area.
