people are always trying to concoct these theories.
"We suspect that this implies the existence of a prior information"---it could have just been any old accumulation/distribution pattern. it could have been based on
any prior information, or none at all. market makers use thick liquidity to put a lid (or a bottom) on markets all the time; ranges are profitable. they don't always succeed, but they usually do because they're just playing into natural supply/demand cycles.
i think the lack of surge is better explained by the simple fact that we're in a bear market. good news is a reason to sell into bounces, and euphoria is short-lived. i'm guessing this guy wasn't trading the corn back in 2014. anyway one remember the paypal pump? probably not, because while price was expected to surge, everyone sold into the pump and price kept falling.....
What was the Paypal pump? I've no memory of that at all.
That amply demonstrates what so many of these people can't wrap their heads around. News, or rather good news, has virtually nothing to do with what the price does. It's going to do what it's going to do no matter what.
2014, Gox and China aside which obviously nullifies everything else anyway, was heaving with good news. The doom train had left the station anyway and nowt was going to stop it.
