This is your regular ADL except instead of hundreds in the basket you've got them condensed into 7 (for now) and in open/close candle form instead of a line.
I'm a bit disappointed because I thought I'd lever more utility from indexes. It may just need some tweaking.
Doesn't it look like Renko?
Reason why it expands:
Total number of constituents is a static 7, to fix that use time to change the total variable based on dates of introduction.
Reallly looks like Renko:
