We can see from the daily candles chart how the Swiss franc stopped when it got to the 1.6493 support, even though the most important support is found at 1.639. Its loss would take the pair down to 1.611. Above, the price is trying to find resistance at 1.6605, which could be a key level to end the day over 1.6665 Swiss francs per pound, which was an important support this month.
