In Elliot Wave Analysis there are only three RULES to keep in mind. Rules should never be broken.
RULE 1: The second wave never retraces more than 100% of the first wave.
RULE 2: The third wave is never the shortest wave among waves one, three and five.
RULE 3: The fourth wave should not enter the territory of the first wave.
Let's see a Safcom chart:

In this safcom chart:
Wave i = (6.10 - 2.50) = 3.60
Wave ii = (6.10 - 2.70) = 3.40
Wave iii = (11.20 - 2.70)= 8.50
Applying Golden Ratio in Wave iii
Wave iii @11.20 =(Wave i X 1.618)+2.70
100% ACCURACY!!!
Wave iv = (11.20-9.60)= 1.60
Therefore, Wave iv is approximately half of Wave ii.
Wave v = 12.80-9.60 = 3.20
Conventional thinkers waste time building shelters when they are unnecessary and then have no shelters when they need them the most. Socionomists do the opposite.
