Indeed, what sideways is this?
Exactly one month ago we were at 41.5 k, that's a 27% drop, this is not sideways at all, on the 5th we were nearly at 40k, again one hell of a drop and no recovery, and this sideways move would have to be also a bit over not just below and recovery.
If I look on a 12h/6h frame at the recent graphs it looks like the sideways move (if any) happened more in February-April when we would go from 45 to 35, 35 to 45, and stay there for a few days at least with good pauses at the 40k level. That looks like sideways movement to me, what we have now is more like a try at stabilization around 30 after one shock.
