This flip is specific to Bitstamp, but China leads the market. Since OKcoin data is missing for the last 8 days
from bitcoincharts, I can only see BTCChina which probably follows OKcoin, and PSAR didn't flip there.
Even if it would flip, it wouldn't mean what the OP implied, that a mania phase of the bubble is near.
For that, considering that the market moves about 4x slower than in 2013 (when Markus and Willy faked it),
we need 4w PSAR to flip (which is not available on bitcoincharts), in order to confirm an upcoming parabolic rise.
