Learn markets by making them.
MOCKX is a real-time trading floor for people, not paper. Spin up a room, hand your friends a join code, and battle it out on a live order book — the way trading firms teach market making.
A real exchange, sized for game night.
Under the hood MOCKX runs an actual matching engine — limit and market orders, price-time priority, partial fills, position limits. Nothing is simulated away. When you get filled, someone on the other side made you pay for it.
Every market needs a truth. In MOCKX, the host knows the instrument's true value and the players don't. Quote wide and you'll never trade; quote tight and you'd better be right.
HOST CREATES A ROOM
Pick a market type — binary event contract or standard instrument — set the round timer and position limits, and share the join code.
TRADERS TRADE
Everyone quotes and trades on a professional depth-of-market ladder — click to place, join, lift, or sweep a level. Keyboard-first, zero friction.
REVEAL & SETTLE
The host reveals the true value. Positions settle against it, the leaderboard updates, and the next round begins.
Everything a trading floor has.
Nothing a classroom needs to install.
A real matching engine
Price-time FIFO order matching with partial fills, market orders, and self-trade prevention — the same rules real exchanges run on.
The DOM ladder
Trade from a depth-of-market price ladder like professional futures traders. One click to hit a bid, join a level, or sweep the book.
Host-run rounds
Timed rounds with pause, halt, and reveal-and-settle. The host is the referee: they set the contract, watch the floor, and call the close.
Two market types
Trade 1–99¢ binary event contracts that settle at $0 or $1, or free-form standard instruments where the market forms wherever you take it.
Live P&L and leaderboard
Marks to fair in real time, settles to truth every round, and ranks cumulative P&L across the whole session. Bragging rights included.
Zero friction
No accounts, no downloads. Players join from any browser with a room code and a display name, and reconnect automatically if they drop.
Play with friends. Train against the house.
PLAY
Multiplayer rooms for game nights, trading clubs, and classrooms. One host, a room code, and a floor full of your friends fighting over the spread. Cumulative leaderboard across rounds.
Create a roomTRAIN
A solo training ground. Market-making bots quote on a live book and you trade against the exchange — tighten your spreads, manage inventory, and drill your P&L before game night. In development.
PreviewMarket making shouldn't live behind closed doors.
The market-making game is how trading firms interview and train: someone knows the true value, everyone else quotes two-sided markets and learns — fast — what adverse selection feels like. It's the best hands-on education in markets we know of, and today it mostly happens on whiteboards behind interview-room doors.
MOCKX turns that game into a real product: an actual exchange with an actual matching engine, playable by anyone with a browser. First a game you host for friends. Then a training ground with bots to practice against. Eventually, a place where anyone can learn to think in prices.
Trading is a skill you learn by doing — MOCKX is where you get to do it, before real money is on the line.
