Cox proportional-hazards model on price vs floor and stack size (fitted on this item). Price effect β = -0.50 ± 0.98: each +10% on price multiplies the sell rate by 0.95. For 1 unit.
Expected gain vs price
Chance to sell vs price
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.
The biggest single posting holds 31% of listed quantity across 12 postings (HHI 0.191, moderately concentrated). Near the floor right now, one posting holds 50% 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.
