By 80th percentile, I do not mean 80% of the maximum depth. I mean: take all of the per-level depth quantities being considered in the visible range, sort those quantities from lowest to highest, and choose the quantity at the 80th percentile. In other words, 80% of the observed depth quantities would be at or below that value and 20% would be above it. For a simple example, if the visible quantities were: 10, 15, 20, 25, 30, 35, 40, 45, 50, 1000 then 80% of Maximum Depth would give approximately 800, because it is based on the single 1000-contract outlier. The 80th percentile would instead be around 45, because it is based on the distribution of all the visible depth quantities. So what I am proposing is another Value Type such as Percentile of Visible Depth Quantities. If Highest Quantity for Coloring is set to Percentile and the input is 80, the study would calculate the 80th-percentile quantity from the same visible depth population used by “Determine Min and Max Levels From = Visible Bars,” and use that calculated quantity as the upper coloring threshold. This would let the heatmap automatically adapt as normal book depth changes through the session without having a single unusually large resting order rescale the entire chart. |
