Green: lin reg of all time price action on Bitstamp Red: lin reg of downtrend
Assuming price is going to spend same time bellow the green line as above it, and also move the same amount (in %). I'm using linear scaling because linear regression doesn't seem to work well on log scale.
We might see a last push towards 130 - 152(last major low). place your bids in this range. After bottoming expect regression to the mean (atleast).
