MarginCall

From the Devs

Every price is discovered, not scripted.

Most trading games decide what a stock is "worth," nudge the price toward it, and paint a chart on top. It looks like a market. It isn't one. You're watching a slideshow with a buy button.

MarginCall fakes nothing. Every tick is a real trade, matched on a real order book between buyers and sellers who each decided, on their own, what a company is worth. No hidden fair value, no script. Just supply, demand, and consequence, the same forces that move real markets.

Simulated all the way down.

A price only changes when two orders match. Every bid is backed by real cash, every offer by real shares. Every trader independently values companies on imperfect information. A living economy sits underneath and drives what companies earn. Crashes, bubbles and bankruptcies aren't scheduled; the market makes them happen, and every move traces back to the exact trade that caused it.

A market that plays fair.

At the core is a genuine central limit order book, the machinery real exchanges run on: real spread, real slippage, real depth that thins when everyone heads for the exit. Trade like a professional with market, limit, stop-loss and trailing-stop orders. Go long, go short, hedge, use leverage, then respect it, because the margin monitor never stops watching, and the moment your equity falls through the line it force-liquidates you. No difficulty slider. The market rewards what you learn and charges you for what you don't.

Every trader has a mind of its own.

Hundreds of participants disagree for real reasons. Market-makers quote liquidity, momentum funds chase trends, value desks buy cheap and short absurd, bubble-chasers pay 200x earnings for a story. Each trades on its own imperfect information, skill and bias, which is why real markets misprice, trend, bubble and break. Hedge funds blow themselves up when they overreach, and you can buy them out.

An economy that feeds the market.

Underneath runs a living economy: industry, commodities, labour and consumer spending across five blocs, each with its own rates, inflation, unemployment and GDP cycle. It feeds what companies earn, earnings feed a real DCF valuation, and valuation shapes what traders will pay. Pull one thread and the whole tapestry moves.

Every finished good traces back through a real bill of materials, from raw resources to the product on the shelf. Mine silicon, refine it into microchips, build those into computers, and sell into a market that actually pays for them. Own a factory at every tier and you capture every margin along the way, or build a data center and sell hosting services, or mine cryptocurrencies instead. A built in visualiser maps the whole graph and rolls up your output and margins across every line you run.

Become the Market Leader.

Accumulate a position and climb from Observer to Consolidated until you own a company outright. Launch IPOs, trigger mergers, force buyouts, take your own company public, then defend it, because a big enough rival stake can oust you as CEO. Act on an insider tip if you dare, but the regulator is modeled too: investigations, fines and bans are real.

A life, not just a game.

Age, health and time matter. Take loans, buy property, pay taxes. Compound a fortune across decades and retire a titan, or push too hard and lose it all. The universe runs off one deterministic clock, so skill is skill, not luck.

The market plays fair. Prove you can beat it.
