CHFJPY - update

Based on wave proportions, I am tracking a potential impulse on senior t/f.
Wave 4 is difficult to trade, as this correction may be a very complicated one.
What is probable and we may take advantage of, is that wave 4 should not overlap with the extreme of wave 1, and the classical are for the fifth wave to start is 38% retracement against wave 3. On the chart this is 1,27-1,38 fibo.
Wave 4 may take a form of a flat or a triangle (simple patterns), or a wxy(xz). Be prepared for a choppy price action for a couple of weeks.
