Understand the mechanics that move prices, from market cap to order books. No jargon, just interactive simulations you can play with.
Market capitalisation is simply price multiplied by the number of units in circulation. A higher market cap doesn't mean a higher price — it's about the total value of all units combined.
Every market has an order book — a live list of buy orders (bids) and sell orders (asks). When you place a market order, it eats through the other side. Watch what happens to the price.
Volatility measures how much a price swings over time. The same starting price can lead to wildly different outcomes. Both paths below start at $100 — hit play to see the difference.
The spread is the gap between the highest bid and lowest ask. It's a hidden cost of trading. Liquid markets have tight spreads; illiquid markets can cost you significantly more.
