How a price is made

Every price you have seen on a chart is the record of one buyer and one seller agreeing, once. Not a forecast, not an average — a receipt for something that already happened. Most of the confusion of the first year comes from reading it as anything else.

A chart shows you where price went. It does not show you how it got there — and those are different questions with different answers. This article is about the second one, because everything else in this stage depends on it.

There are always two prices, never one

At any moment the market holds two numbers: the highest price someone is currently willing to pay, and the lowest price someone is currently willing to accept. The bid and the ask.

The distance between them is the spread. Nobody charges it and nobody collects it — it is simply the gap between what one side hopes for and what the other will settle for. And the single price quoted on a chart is neither of those two: it is the price of the last agreement, already in the past.

Diagram 1. What is waiting on each side, and the gap in between. Nothing is traded inside the spread: a price exists only when somebody decides to cross it.

Somebody has to cross

Orders that sit and wait are passive. Orders that take what is already waiting are aggressive. Every single trade is one of each — someone who was patient, and someone who decided that waiting was worse than paying the spread.

Limit — passive: Joins the queue at a chosen price and waits its turn. What it costs is time, and the risk of never being filled at all.
Market — aggressive: Takes whatever is available right now. What it costs is the spread — and more than that when the book is thin.

This is the whole mechanism. Not a theory about it — the mechanism. Price does not move because of a pattern or a level: it moves because somebody kept crossing until the other side ran out.

The moment a price is printed

Watch it in three steps and it stops being abstract.

Diagram 2. A price is not found, it is consumed. The market moves up because the sellers at that level are gone, not because anyone decided the market should be higher.

What a candle cannot tell you

Here is the part that matters, and the reason this article comes before all the others.

Two very different situations produce exactly the same candle. In the first, buyers pushed through a wall of sellers — real supply, absorbed and beaten. In the second, there was almost nobody on the other side, and a small order was enough to walk the price up.

The chart draws both identically. One is strength; the other is an empty room.

Diagram 3. Identical candles, opposite meanings. The difference is not on the chart — it is in what was waiting on the other side, and it is gone by the time the candle closes.

Why this one comes first

Everything else in this stage — the tape, the footprint, delta, absorption, imbalance — is a different instrument pointed at the same event: somebody crossed the spread, and something on the other side either held or ran out.

Read those tools without this, and they are patterns to memorise. Read them with this, and they stop being separate tools: they are one story told from four angles. That is the reason to start here rather than with something that looks more advanced.

None of it tells you what to do next. It tells you what just happened, which is a smaller claim and a far more reliable one.

If you want to go deeper

Two, not twenty. What was left out matters more than what is on the list.

Mind Over Markets

James Dalton

The auction explained by someone who watched it before screens existed. Slow going, and worth it — most of what people call «order flow» today is a footnote to this.

Trading in the Zone

Mark Douglas

Not about order flow at all. It is about why you will ignore what you just read the moment money is on the line, and it is the honest half of this job.
