Exchange is a frontier commodities-trading incremental game. You are a lone trader building a fortune on a network of markets where prices move every day — driven by trends, cycles, volatility, and sudden news shocks. Read the regimes and allocate: buy low, sell high, and ship goods between markets to capture spreads. But arbitrage is never free — goods are locked in transit for days, so every spread is a timing bet. Manage real risk. Borrow on margin to amplify returns, but mind your maintenance margin: fall below it and your positions are force-sold. Push too hard and a margin call becomes bankruptcy. Retire and Refound to bank Reputation, scaled by your peak net worth, and spend it on permanent edges: more starting capital, cheaper fees and shipping, a bigger credit line, short selling, futures, optional securities desks, and rule-based automation so the late game runs hands-off. Features: • Five markets, ten commodity complexes, each with its own price regime • Inter-market shipping with route modes, transit time, cost, and arrival moments • Delivery contracts, closing auctions, and net opportunity scoring • Leverage, interest, margin calls, and the genuine risk of ruin • Short selling, futures, and optional paper desks unlocked through prestige • Standing-order automation for hands-off trading • A deterministic, seeded simulation — runs play out reproducibly • Offline progress: the markets keep moving while you're away Trade well.
