I swore off trading the CHF after the infamous 2015 SNB-inspired flash crash (new traders should Google it) but JP has alerted me to perhaps start trading it again.
This chart shows a failed breakout and subsequent retreat. Ket levels can be seen in the chart.
The CHF along with the JPYT are two of the most sensitive currencies to moves in US interest rates although respective central bank risk is in the opposite direction. . The SNB is seen as the most likely CB to cut interest rates first while the market is waiting for the BoJ to finally raise rates.
