[one trade]  This is more likely my style but an acquaintance showed me the record of a sale of a small amount of bitcoin from an exchange and even though he sold much less than one bitcoin in what he thought would be one transaction,  there were many, many small transactions as buyers nibbled away at it.  I would think if it was all at the same time and for the same price, there would be no need to break it down like that though.
