How financial markets work

A market price is the level at which a buyer and a seller last agreed to transact. It is not a valuation, a forecast, or a fair number. It is a record of the most recent agreement.

That agreement changes constantly. When more capital wants to buy at the current level than sell, price moves up until enough sellers appear. When the imbalance runs the other way, price moves down. This is the whole mechanism. Every pattern, every framework, and every analysis built on top of markets is an attempt to describe that imbalance before it resolves.

Behind the single number on a chart sits a list of resting orders: everyone willing to buy, at the prices they are willing to pay, and everyone willing to sell, at the prices they will accept. That list is the order book.

The highest price anyone will pay and the lowest anyone will accept sit next to each other with a gap between them. A trade happens when someone crosses that gap and accepts the other side's price rather than waiting for their own to be met.

This is why a large order moves price. It consumes the orders resting at the best level, then the next level, then the next, each one worse than the last. The move is not a reaction to the order; it is the order working through the available supply of counterparties.

The depth of that book is what liquidity means in practice. A deep book absorbs a large order with little movement. A thin one does not.

Most price movement has no headline attached. Large positions take hours or days to build, because filling them at once would move the market against the buyer. A fund accumulating a position produces steady pressure with no announcement behind it.

Scheduled events concentrate this. A central bank decision forces every participant to reprice at the same moment, which is why volatility clusters around the calendar. Between those points, price drifts on ordinary buying and selling of the instrument.

The other reason is that information reaches the price before it reaches the reader. By the time an explanation is published, the participants who acted on it have already acted. A move that looks unexplained is frequently a move whose explanation has not been written yet.
