A similar situation is happening now. Then a breakthrough of the uptrend line, price fixing below the uptrend line and another -81.5% market fall. Previous highs were updated only after 25 years.
The situation on the Dow Jones now. A very similar schedule as in 1930. It is important how the price will react near the uptrend line, which will act as a support. If there is a breakdown of the uptrend line and the price consolidates below it, a very dangerous situation will arise like in 1930 and a complete collapse of the US economy. Let's hope this does not happen.
