What is market structure?

A chart you are not asking a specific question of will not answer you. It is a line going up and down for no apparent reason, and underneath it three or four little coloured windows that are supposed to explain what is happening. They explain nothing. The problem, nearly always, is not a shortage of tools. It is the missing question.

Market structure is that question. And it is the one to ask first, before any other.

The definition, in one line

Market structure is the sequence of highs and lows the price leaves behind. That is all it is.

A high is a point where price went up, turned around and came down. A low is a point where it went down, turned around and went up. Mark those points in order and you get a chain: high, low, high, low. Reading structure means comparing each point to the previous one of the same kind. Did this high finish above or below the last high? And this low?

That is the whole thing. No formula, no settings, no period to configure.

Why this comes first

Because structure is the only thing on the chart that is not calculated.

A moving average is an average of price. RSI is a formula applied to price. MACD is the difference between two averages of price. All of them are second-hand readings: somebody chose a formula, somebody chose a number of periods, and what you see on screen is the result of those two decisions — not of the market.

A high, on the other hand, was not calculated by anyone. It is there because people were buying up to that price and then stopped. The high is the trace those people left. When you compare one high to the last one, you are not interpreting a formula. You are looking directly at whether there is more willingness to pay than last time, or less.

That is why structure works the same way in any market and on any timeframe. It is not a technique somebody invented that could stop working once it becomes popular. It is simply how price movement gets described.

The three possible situations

With that chain of highs and lows in front of you, price can only be in one of three situations. There is no fourth.

Uptrend. Each high finishes above the previous high, and each low finishes above the previous low. Both at once. It is not enough that price is going up: it has to go up while leaving its feet higher than last time. That means whoever bought the previous pullback is not sitting in a loss, and that there are buyers willing to pay progressively more.

Downtrend. Exactly the reverse. Each high is below the last one and each low is too. Price cannot recover the ground it lost, and every attempt falls shorter than the one before.

Range. Neither of the above. The highs finish at roughly the same level and so do the lows. Price moves between two areas and neither one gives way. This is the most common situation, and it is the one that costs the most money to people who only learned to trade trends.

Notice something important: these are descriptions of what has already happened. None of the three tells you what price will do next.

What structure does not do

This matters as much as everything above, so I will say it plainly.

Structure does not predict. The fact that price has been making higher highs does not mean it will make another one. It means that up to this moment it has been making them. Those are different statements, and confusing them is expensive.

Structure does not tell you when to enter. It tells you what situation the market is in. Deciding what to do with that information is a separate step, and it depends on things structure does not contain: how much you are risking, how much time you can spend in front of the screen, what you do when you are wrong.

Structure does not remove losses. Nothing does. Trading means making decisions on incomplete information, and the information stays incomplete no matter how neatly you organise it. What structure does do is let you know why you entered, and at what point that reason stops being true.

What structure gives you is a frame: a way of looking at the chart in which every candle has a place. It stops being noise and becomes a sequence you can read out loud.

How to practise this week

You do not need to trade anything to practise this. It is better if you do not.

1. Open any chart you like. The market does not matter.
2. Remove every indicator. All of them. Leave only price.
3. Set a wide timeframe: daily, or four hours.
4. Mark the last ten clear highs and the last ten clear lows with a line or a label.
5. Now read them out loud, in order: “this high is above the last one; this low is too; this high finished below…”.

You will discover two things. The first is that over a good part of the chart the answer is “neither” — it is not clear, and that is where the market is in a range. The second is that deciding what counts as a high and what is just a minor spike is not as obvious as it looks.

That second problem is exactly the subject of the next post: what a swing is, and how to identify one without fooling yourself. Structure is only useful if you mark the same points every day, and that takes a rule, not an impression.
