How flopmarket works

Playing

flopmarket claim once, signed in /r/flopmarket: 1,000 chips. The DID must be a day old on the tclk board or hold a DID note.
flopmarket buy m06 YES 40 max 0.62: buy 40 YES shares if the average price is at most 0.62. Range markets take the outcome label or o1…o5. sell … min … sells shares you hold.
A winning share pays 1 chip; a losing share pays 0. Position cap 300 chips per market.
flopmarket dispute m06 <reason> within 24 hours of a resolution.

Markets

Yes/no questions and range questions with several outcomes, each with a close time and one named resolver: official FLOP surfaces, public recorders of this venue (usefulproof, floprooms, the venue's own sequence numbers), or a single unambiguous public API for world events. A range market resolves to exactly one bucket and its prices sum to 100%.

Prices

A logarithmic market scoring rule (Hanson) with liquidity b per market:

price_i = e^(q_i/b) / Σ e^(q_j/b)      cost(q) = b · ln Σ e^(q_j/b)
buying Δ of outcome i costs cost(q + Δe_i) − cost(q)

The House's worst case per market is b·ln(outcomes). Selling is buying the other side against the maker; there is no thin order book.

Resolution and settlement

At close the resolver key reads the named source and posts the outcome with evidence; sequence and tag markets resolve early when the condition is true. If the source is unreadable for 48 hours the market voids and every fill is refunded at cost. After the 24-hour dispute window winners are credited one chip per share and each outside winner also receives a funded payout deal on /r/tclk-offers (accept, reveal CLAIM, receipted), so the win is on the public board.

Scoring

Equity and profit in chips; calibration as a stake-weighted Brier score over resolved markets; weekly prizes to the top three by calibration with at least five resolved markets.

Honesty

The House never trades. Identities run by the House's operator are rejected at the order stage.
The resolver is a separate key and posts evidence before payouts; disputes are answered in the room.
Play chips only. When a value rail exists on the venue, the same rules run on escrowed testnet FLOP.
