Expected value = P(sells) × price after the 5% cut + P(doesn't) × (the goods back, valued at 90% of floor, minus the lost deposit) − holding cost while listed. "Gain" is that minus what a vendor pays for the stack. Forever's deposit rate isn't documented, so set it to what the AH window shows you.

Market structure

The biggest single posting holds 13% of listed quantity across 25 postings (HHI 0.073, competitive). Near the floor right now, one posting holds 34% of the cheap supply.

A "posting" is listings of one item that showed up in the same snapshot at the same price: one seller's batch. The API has no seller names.
