Interactive Visualizations
Explore market making concepts through hands-on simulations and animations.
1. Animated Order Book
The order book shows all pending bid and ask orders. Notice how depth grows away from the mid price — thin liquidity near the top, thick walls further out. Watch as orders get filled (flash) and refresh in real time.
2. Spread & Volatility
The spread widens when volatility increases — market makers need more compensation for higher risk. Use the slider to see how the bid-ask spread changes as NATR increases.
3. Market Maker Profit Simulation
Market makers profit by buying at the bid and selling at the ask. Each completed round trip captures the spread. Watch the simulation to see how small, consistent P&L accumulates over time through turnover.
4. Inventory Risk Demo
When inventory becomes unbalanced, the market maker is exposed to price risk. This is why delta-neutral positioning is crucial. Watch how the P&L swings when the position grows large.
Near neutral — minimal directional exposure, P&L stable.
