Price, time and "specific volume" (in each unit time).... Specific volume is corrected for time of day using recent historic norms (total Naz), gee, now the Kimono is fully open....
Thanks and you're right I was mistaken. I think the 3rd axis is signal data extracted from time price. Decomposition is a word that comes to mind. I doubt the 3rd axis contains time based signal ...but I like it for storing price relationships.
There's too many 2D parallelograms in the series. It can be truncated to allow for a 3rd signal axis but I can't picture it yet. 2 parallelograms seems like plenty.
