Take a look at the EUR/USD and USD/CHF 1 hour chart. For this time period, it shows that the pairs moves in mirror opposite directions which I believe shows that there is negative correlation between EUR/USD and USD/CHF. The current correlation may be due to the close ties between the EU and Switzerland. I think we can double our profits by opening one long and one short position of the two pairs. However it could also double our losses if we do not trade carefully.
