Why markets exist

It all starts with a simple problem

Imagine a farmer with too much wheat and a fisherman with too much fish. Barter sounds simple, until the fisherman doesn't want wheat, or the wheat is worth three fish and a half. Economists call this the double coincidence of wants: for barter to work, both sides must want exactly what the other has, at the same time, in compatible amounts. That almost never happens.

Money solved the mismatch: a neutral 'in-between' good that everyone accepts. But money created a new question that has driven every market since: *how much is something worth right now?* Not last year, not in theory, right now, between real buyers and real sellers.

Price discovery, the heartbeat of every market

A market is simply a place, physical or digital, where buyers and sellers meet and negotiate price in public. When more people want to buy than sell, price rises until sellers show up. When more want to sell, price falls until buyers find it attractive. This continuous auction is called price discovery, and it is exactly what you watch on a chart: thousands of negotiations per second, compressed into candles.

• Markets exist to solve the matching problem: connecting people who want opposite sides of a trade.
• Price is not decided by anyone, it emerges from the auction between buyers and sellers.
• A chart is a *record of negotiations*, not a random squiggle. Learning to read it = learning to read the auction.
• Everything you will learn in this academy, candles, levels, trends, is a way to read that auction.
