The range is moving down via a SQRT curve of sorts - we aren't ever breaking zero again and if we touch -.5, sell everything! I like this indicator, but it should somehow evolve away from log and towards a more gradual curve. I patiently waited for another 1.5 on the last run up without realizing this.
No need to abandon the log scale. Only needs judicious choice of curve. SQRT it is.
I ran some numbers on the price history and fitted a square root baseline. Vertical axis, log of dollars.
This chart shows the relation between the price and the baseline over time.
This is a great piece of work and just what I'm looking for.
I'm putting together a series of indicators and trends for a news site,
www.bitcoinbulletin.org. The idea is to offer fundamental/long term price development and projects as well as short term indicators. The first category will include 200 WMA, log curve and 'expert' predictions for context; the second signals like NVT and Fear/Greed Index.
I've been particularly interested by Peterson's work on Facebook/Bitcoin network size, time and price in this paper:
https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3356098 This has proven an extremely good baseline for bitcoin's 'clean' price (i.e. non-bubble price).
@birr do you have the equation you used for that square root baseline? I've been struggling to come up with something meaningful myself.
Appreciate the work you've done on this and thanks in advance.
