It seems like the price is following the "punctuated equilibrium" pattern similar to June-Sept 2016. The pattern looks like a series of sudden price adjustments followed by a sort of damped oscillation converging at various levels. Summer 2016 price converged to ~660, then ~570, then a final convergence in-between to ~610 before transitioning to a slow exponential rise.
After the recent sudden price changes, price first converged to around 900, then to ~830.
The difference this time is the time period of the punctuations. Last summer the punctuations were about 5 weeks apart, now they seem to be about 5 days apart.
This makes sense, because as soon as a pattern becomes apparent, we can expect traders to anticipate it, trying to front-run the price movements. This has the affect of speeding up , then eventually destroying, the pattern.
