Volume and Market Structure

Module 2: How Markets Move

9.1

Price tells you what. Volume tells you why.

Imagine you are watching a tug of war. Two teams are pulling on a rope. From a distance you can see who is winning. The rope is moving toward one team. But you cannot see how hard each team is pulling. Are the winners pulling with everything they have? Or are they barely trying while the other side has already given up?

That distinction matters enormously. A team that is winning effortlessly is likely to keep winning. A team that is winning but visibly struggling, with their opponents still fighting hard, might not be winning for much longer.

Price is the rope. It tells you which direction the market is moving. Volume is how hard each side is pulling. It tells you whether the move has genuine conviction behind it or whether it is happening in a vacuum with nobody really committed to it.

A price move on high volume means many participants are acting with conviction. They believe in the move strongly enough to commit real money to it at that price. A price move on low volume means fewer participants are committed. The move might be real but it lacks the broad participation that gives it staying power.

9.2

What volume actually shows you

Volume is simply the number of units traded during a given period. On a stock it is the number of shares exchanged. On spot forex volume data is harder to access because the market is decentralised, but tick volume, the number of price changes per period, is widely used as a proxy and correlates well with actual volume.

On most charts volume is displayed as a series of bars at the bottom of the chart, one bar per candle period. Tall bars indicate high volume. Short bars indicate low volume.

The most important thing to understand about volume is that it validates or questions the price move it accompanies.

A strong upward price move accompanied by high volume is telling you that buyers are genuinely committed. Many participants acting with conviction drove that move higher. It is a healthy move. The trend is likely intact.

The same strong upward price move accompanied by low volume raises a question. If this move is so strong, why are so few people participating in it? Who exactly is buying? And if the buying dries up, what happens to the price?

9.3

Volume signals every trader should know

Volume expanding on a breakout is one of the most important confirmations in technical analysis. When price finally breaks through a resistance level that has held multiple times, you want to see volume expanding on that break. High volume on the breakout tells you that a significant number of participants believe the break is real and are committing money to it. It is the collective action of the market saying the level has been broken and a new direction is beginning.

A breakout on low volume is suspicious. It suggests that only a small number of participants are behind the move. These breakouts frequently reverse. Large institutions sitting with orders at the resistance level are not convinced, and when price returns to their level they step back in and push price lower. This is called a false breakout and low volume is one of the best early warning signs.

Volume declining in a trend is a warning sign. In a healthy uptrend each successive push higher should ideally be accompanied by solid volume. If the trend continues to make new highs but volume is declining with each push, each new high achieved with less and less participation, it suggests the trend is running out of buyers.

Volume spiking at a reversal point is often the climax of a move. When price has been falling for an extended period and suddenly a candle appears with volume many times higher than normal, it often signals that the final desperate sellers are being absorbed by buyers. This is sometimes called a selling climax. The enormous volume represents the last wave of panic selling. After it exhausts itself there are no more sellers left and price stabilises or reverses.

Volume Signals at a Glance
  • High volume on a breakout confirms that participants believe the move is real and are committing money to it
  • Low volume on a breakout is suspicious and frequently leads to a false breakout reversal
  • Declining volume in an uptrend as price makes new highs suggests the trend is running out of buyers
  • A volume spike after an extended decline often marks a selling climax, the final wave of panic before price stabilises

Market structure — the map beneath the chart

Market structure is simply the pattern of highs and lows that price has created over a given period. It is the skeleton of the chart, the framework that tells you at a glance what the market has been doing and therefore what it is likely to do.

You already know the basics of market structure from Chapter 5. An uptrend creates a series of higher highs and higher lows. A downtrend creates lower highs and lower lows. A ranging market creates relatively equal highs and relatively equal lows.

But market structure goes deeper than just identifying the trend. It tells you which levels matter most, not because they appear on a horizontal line but because the market itself created them and has been respecting them.

The most recent higher low in an uptrend is a structural level. It is the last point where buyers overwhelmed sellers and pushed price to a new high. If price pulls back to that level and holds, the uptrend structure is intact. If it breaks below it, the structure has changed. Something has shifted.

9.5

Break of structure — the most important signal

A break of structure is the moment when the sequence of highs and lows that has been defining the market changes.

In an uptrend, every low is higher than the previous one. Each pullback respects the structure. Price comes down, finds buyers at a higher level than before, and continues up. This is the structure working as it should.

Now imagine price pulls back and breaks below the most recent higher low. This is a break of structure. The sequence that has been defining the uptrend has been interrupted. Something has changed.

This does not automatically mean the uptrend is over. Markets frequently break structure temporarily before resuming. But it is a significant event that demands attention. It means you should be less confident in holding long positions, more cautious about adding new ones, and alert to whether the market can reclaim the broken level or whether it continues lower.

The most reliable scenario after a break of structure is often a retest. Price breaks below the higher low, the structural break, then rallies back toward that level from below. If price fails to reclaim the broken level and turns lower, it confirms that the structure has genuinely changed and a new phase is beginning.

Key Takeaways
1
Volume measures the number of units traded during a period. It validates or questions the price move it accompanies.
2
Strong price moves on high volume indicate genuine conviction. The same moves on low volume are suspicious and more likely to reverse.
3
Volume expanding on a breakout confirms the break is real. Low volume breakouts frequently reverse as false breakouts.
4
Market structure is the pattern of highs and lows that price creates. It is the skeleton of the chart and shows the balance of power between buyers and sellers.
5
A break of structure, when the sequence of higher highs and higher lows or lower highs and lower lows is interrupted, is a significant event that demands reassessment of any open trades and future setups.
