EUR/CHF is attempting to break out of a Triangle pattern it has formed over the last three months (see chart below).
A bearish close on Tuesday will indicate a decisive breakout has happened and suggest the start of a likely strong decline.
The market activity prior to the formation of the Triangle (Since May 27) further tips the odds in favor of a downside evolution.
If EUR/CHF breaks below the 0.9307 level (September 11 lows) it will further confirm an authentic bearish breakout, with the next target to the downside at 0.9132, the 61.8% Fibonacci extrapolation of the height of the Triangle lower.
