About
Market Price Simulator is a free, browser-based market simulation that lets you experiment with how prices actually form.
I couldn’t find a tool that clearly shows how supply and demand, order volume, and different market participants affect price movement — so I built one.
You can create multiple traders, place buy and sell orders at specific prices, and instantly see how trades execute, how the order book changes, and how prices evolve over time. Large orders move the market differently than small ones, and the effects are visible immediately.
There’s no registration, no paywall, and everything runs locally in your browser. It’s designed for curiosity, learning, and experimentation — whether you’re new to markets or just want a clearer mental model of how trading works.
What makes it stand out:
Real-time order matching and visible order book dynamics
Multiple traders with independent balances (big players vs small players)
Clear visualization of price history and executed trades
Free, instant access — no signup required
A true sandbox for understanding market mechanics, not a trading platform
