S&P 500 index 1wI analyzed the logarithmic graph. Price moves in the channel where the middle of the channel plays a huge role, determining the trend and price limits.
On the story, when the price went below the middle of the channel, the rate of decline before the correction was from 14 to 161 days in 2008, I think now the situation is closer to 2008.
He measured: when breaking through the middle of the channel, the maximum correction was 58% of the beginning of the correction and 46% of the middle of the channel, the minimum - 36% and 31% of the middle of the channel.
Thus, we have two zones where the price can end its fall.
