Long Term trend-line since 1929 Chart (2)

With this idea there's another possible rally in the next 4 years that pushes us back up to the 5500 - 6200. Under that scenario would put wave 5 at 18 years long. Scenario 1 only puts wave 5 at 12.7 years long which is a lot shorter then the previous waves. All thoughts are welcomed
Thank You
