I kept the algorithm exactly the same, but changed the layout and the default look back period. Most important is that the resulting line, the TPX, is now a histogram with green and red staves.
To put the histogram on a logical place in the graph, I changed the way the control/dominance level is implemented, it now lowers or highers the whole graph, this way the zero level becomes the ‘no interest’ level.
I added two horizontal lines at a distance of 40 because I feel that this is sort of an oversold / overbought indication. In practice not very convincing, but provides a visual comparison.
In this layout I explain that grass is growing on bull hills peaking up behind the foreground and blood is dripping from the bear hills.
