Another plot for those who are interested...
I superimposed the current trend (over the last 50 days) with the run-ups to the April and November 2013 peaks.
We still seem to be right on track for a peak between $4000 and $5000...

Good news is we only need to wait a fortnight (maximum) to find out if history will repeat itself.
Note: This plot has the peak occurring in late July, which is based on the assumption that the peaks occur (approximately) every 234 days (an assumption based on historical data).
