Trading Floor

Trading Floor

Mandalay Markets — long-only futures and call/put options on NYSE equities, commodities, and crypto. Contracts come from a stored catalog (trading_catalog.json, 700+ listings) with filterable pages. Underlyings and performance series live in market_symbols.json.

Game flow

Trading Floor → Category filter → Live tape (full book or isolated class) → 1D/1W chart + recent prints → Buy contract → Settle / expire → Wallet updated

Symbol database

market_symbols.json holds every tradable underlying (NYSE, commodities, crypto) with base spots, synthetic 1D/1W performance, and chart series. The live tape random-walks from those marks.

Live underlying tape

• All assets — full-spectrum scroll of every symbol
• Category chips — isolate NYSE / Commodities / Crypto on the tape and charts
• Chart toggle 1D / 1W plus recent print activity before you buy
• Buy screen keeps a focused ticker on the selected underlying

Asset classes

Class	Examples
NYSE	Large-cap equities & index proxies
Commodities	Energy, metals, softs
Crypto	Major coins and pairs

Instruments

Instrument	Entry cost	Settlement
Future	Margin stub ≈ 10% of notional (min 25 chips)	PnL = (exit − entry) × multiplier × qty
Call	Premium = ask × multiplier × qty	Intrinsic = max(0, spot − strike)
Put	Premium = ask × multiplier × qty	Intrinsic = max(0, strike − spot)

Exit spot is the contract mark drifted by a small random move at settlement. No naked shorts.

Filters & paging

• Asset chips: All / NYSE / Commodities / Crypto (also scopes the ticker)
• Instrument chips: All / Future / Call / Put
• Next contract page advances the catalog cursor within the active filter

Minimum trade

25 chips.
