For buyers
Read the all-in SOL per APU quote
The number that ranks the book is the full SOL you pay, divided by APU you receive.
What all-in means
All-in SOL per APU is buyerPaysSol divided by buyerReceivesApu. It is the figure the home desk sorts on.
A cheaper all-in ask clears first in the ranking even if another row shows a rounder size.
What the four amounts are
You pay the quoted SOL. They receive 87.5% after the 12.5% fee. You receive 100% APU. The fee line is the book’s share.
Those four numbers come from the Econext quote. If they do not match the size you typed, wait for the quote to refresh before you lock.
