Looking at the price records for the three previous bubbles, we see . . .
June 9, 2011 peak at $32 - doubling from $16 in 4 days.
April 10, 2013 peak at $260 - doubling from $130 in 7 days.
November 29, 2013 peak at $1163 - doubling from $581 in 13 days.
The November peak is interesting because the rally to $758 on November 18, doubled from $359 in 6 days. I therefore thought that $758 was the peak, but the correction down from $758 was only to $379 which did not appear deep enough to me and other observers that day.
I suspect that the next bubble, being widely anticipated will have one or more dramatic pre-peak spikes that double in about a week.
I will combine the doubling time indicator with a threshold from the Log10 Delta From Trend chart when predicting the next peak.
Seeing as how each doubling to peak has taken x*2-1 days (where x is the previous bubble's # of days for price to double to peak), do you think it is possible that the next doubling to peak might take roughly 13*2-1 or 25 days to occur?
