"For nonlinear trends in time and areas of high probability, how are reversals detected? To gain intuition, first consider the difference, when looking at a bar chart, of a linear trend versus a congestion: One observes that, on the same time interval, there is a divergence between the degree of overlap of bars, as seen projected onto the price axis (as if a light was shining on them from the right). For a trending market, that overlap, or shadow, is lighter than for a congested market. This gives rise to the shadow index."
Has also good capabilities at predicting an increase of .
"Now, when the market is in a linear trend or a congestion, the DS I will be high. On the other hand, it will be low when the market accelerates away from a linear trend. So a pattern of mean-reversion exists for the DS I but the times when it is low are rare, because so are accelerations."
