Demo 2: Payout Ledger
This version treats predictions like a real auction-house payout board: bought price is the observed listing price, quantity is capped by what was actually listed, and jackpot means positive expected value after changing sale chance, the 5% auction cut, failed-sale reposts, and 24-hour posting deposits.
Rows are collapsed to one simulated trade per item, market, and buy day. Price-drop predictions are excluded because they train the model; they are not gold-making trades.
How the payout is calculated
Gold result
Jackpot is total expected value, not guaranteed gold. It models 24-hour postings through the prediction horizon.
Expected gold = expected sold quantity x successful-sale profit - expected deposit risk
Successful-sale profit = checked sell price x 95% AH cut - observed buy price
Expected failed quantity = suggested buy quantity - expected sold quantity
If sale chance is 30%, the ledger expects some items to fail to sell and need reposting. Deposits are charged for the first post and each expected repost.
Inputs used
- Observed buy price: the price present when the prediction was made.
- Checked sell price: the later observed market price at the prediction horizon.
- Sale chance: averaged from the same item, realm, and faction snapshots between the buy time and score time where hourly history exists; otherwise the row falls back to the stored buy/sell checkpoints.
- Sold/day, price, and supply: read from the same market window where available and shown as market checks in the sold column.
- 24h deposit: vendor-based 24-hour auction deposit where item vendor value exists; otherwise a conservative fallback estimate is used. Reposts add more deposit risk.
- Suggested buy quantity: capped by listed supply, sold/day, confidence, manipulation risk, expected ROI, and a 100g test budget.
