This is actually real cool. Just messing with settings on 4hr btc all time chart... there are some interesting potential models that can be derived already. I'll have to mess with this a bit and see if I can produce any attractive models just to see if they hold up in the future as an experiment. Seems like a weird formula to derive models from but I feel there is something here... I'm a noob though maybe its obvious haha
