Anticipating the completion of wave {iv} of 3 before ZIM continues its journey higher through 23.78 and towards the 30-40 range in wave {v} of 3.
Current price levels make a good candidate for a bottom for wave {iv} of 3. Ideal Fibonacci proportion exists where wave {iv} of 3 equals 0.382 the distance of wave {iii} of 3 and wave (c) of {iv} equals wave (a) of {iv} around the bottom of the wave {iv} of 3 corrective channel at 16.80-17.00.
The guideline of alternation also comes into play between the corrective waves {ii} and {iv}. The guideline of alternation states that within an impulse wave, when wave two occurs as a sharp correction (zigzag, double/triple zigzag), expect wave four to develop as a sideways correction (flat, triangle, or combination). Here we can see that wave {ii} has developed as a zigzag and now wave {iv} appears to be developing as a flat, textbook wave behavior.
If price has any lower to go, it should be contained by the wave {i}-{ii} base channel around 14.50-15.00 and ultimately should not violate the wave {i} high of 11.50 as that would invalidate the pattern.
An impulsive reversal through 18.54 would be the first step to confirming that wave {iv} of 3 is complete and wave {v} of 3 is in progress towards and through 23.78.
