When you first open a cryptocurrency candlestick chart, do you only focus on that jumping price line? Most beginners make this mistake: staring at the price's ups and downs while ignoring the row of varying-length bars at the bottom of the screen—the trading volume.

If price is the 'appearance' of the market, then volume is its 'truth.' Price tells you what an asset is worth right now, while volume tells you how many people agree on that price. Today, we'll delve into a core question that puzzles many newcomers: Why does 'volume precede price'? Learn to understand the true meaning of cryptocurrency volume and find your way in the foggy market.

The Essence of Volume: Why It's Called the Fuel and Lie Detector of the Crypto Market

You can think of the crypto market as a car climbing a hill. The price increase is like the car accelerating towards the summit, and the volume is the fuel in the tank.

If the car is accelerating uphill (price rising) while the engine roars and fuel consumption is high (volume increasing), it means there's plenty of power, and the car is likely to reach the top. This is called 'real market demand.'

Conversely, if the car is trying to climb, but the gas pedal is floored and it's out of fuel (volume shrinking), even if inertia keeps it moving forward, it could roll back at any moment due to lack of power. This is volume's role as a 'lie detector': it can expose fake price movements. When the price rises without volume support, it often means the market is internally weak, and such a rally is usually unsustainable.

The Core Logic: A Deep Dive into the True Meaning of 'Volume Precedes Price'

There's an old saying in financial markets: 'Volume precedes price.' This isn't just a slogan; it's a physical law of market operation. To truly understand why 'volume precedes price' and grasp the true meaning of cryptocurrency volume, we need to look at it from the perspective of capital flow.

Imagine a large amount of capital (often called 'whales' or 'smart money') wants to buy an asset. They can't do it all in one second, or the price would skyrocket, making their cost too high. Therefore, they buy quietly and continuously.

During this phase, the price might seem calm, even moving sideways, but the volume bars below will start showing dense 'small peaks.' This is 'volume preceding price'—the entry of capital (volume) often happens before significant price fluctuations (price).

It's like the wind before a storm. The wind (volume) moves first, and then the waves (price) rise. When you observe unusually high activity in volume in a bottoming area while the price remains relatively stable, it's often a leading indicator of an impending market shift.

The Four Basic Volume-Price Relationships: How to Confirm Trend Validity with Volume

After understanding the underlying logic, let's look at the four most common 'volume-price coordination' patterns in daily observation. Mastering these will help you judge whether the current trend is healthy.

• Volume Increases, Price Rises (Healthy Uptrend): The price goes up, and volume expands simultaneously. This is like the 'fueling up to climb the hill' analogy, indicating widespread market agreement on the price rise, strong buying interest, and a high probability that the trend will continue.

• Volume Decreases, Price Rises (Weakening Uptrend): The price is rising, but the volume is shrinking. This is often called a 'divergence.' Imagine at an auction, the price gets higher and higher, but fewer and fewer people are raising their paddles. This is a warning sign, suggesting that buying power is exhausted and the price could fall at any time.

• Volume Increases, Price Falls (Panic Selling): The price drops on huge volume. This means someone is dumping their holdings frantically, and many others are either buying the dip or their stop-losses are being triggered. It usually represents spreading panic and heavy selling pressure in the short term.

• Volume Decreases, Price Falls (Indecision/Apathy): The price drifts lower on low volume. This indicates the market is in a lull where 'no one is buying, and no one is selling.' Holders are unwilling to sell at low prices, and outsiders are hesitant to enter. This slow bleed is often the most patience-testing phase.

Advanced Practical Signals: Identifying Volume-Price Divergence and Potential Reversal Opportunities

In practical application, the most valuable signals often appear when 'common sense' is broken. This is known as 'volume-price divergence.'

Try to imagine this scenario: a team of long-distance runners (price) is sprinting, getting faster and faster (making new highs), but their breathing rate and stride (volume) can't keep up.

• Bearish Divergence (Top): When the price makes a new high, but the corresponding volume peak is lower than the volume during the previous rally. This shows that although the price has gone up, the force driving it is weakening. This is a strong potential topping signal.

• Bullish Divergence (Bottom): When the price falls below a previous low to make a new low, but the volume is significantly less than during the last drop. This indicates that selling pressure is exhausting; although the price is still falling, it's becoming 'unsellable.' This is often a precursor to a market bottom and rebound.

According to historical market data analysis, over 60% of major trend reversals are accompanied by some form of volume-price divergence. Learning to identify it is like having the ability to forecast changes in the weather.

Beware of Data Noise: Common Fake Volume and Traps in the Crypto Market

Although volume is a 'lie detector,' in the nascent crypto market, even the lie detector's data can sometimes be 'interfered with.' You need to be especially wary of 'fake volume.'

It's like some popular restaurants hiring people to queue up to create a false impression of being busy. In the crypto market, this practice is called 'wash trading.' Some market makers or project teams may trade between their own accounts to create huge trading volume and attract retail investors.

How to identify?

1. Check the Order Book Depth: If the volume is huge, but the bids and asks on the order book (market depth) are very thin, it's likely faked.

2. Examine the Candlestick Pattern: Normal volume usually appears as continuous, fluctuating waves. If you see perfectly uniform 'barcode-like' volume, or a sudden, massive spike that immediately drops back to zero, you should be highly suspicious.

Building a Trading System: How to Integrate Volume Analysis into Daily Trading Decisions

Finally, don't try to fight with only one weapon. The greatest strength of volume analysis lies in its ability to validate the effectiveness of other indicators.

You can try building a simple decision-making process like this:

1. Trend Identification: First, look at the price action and moving averages to determine if the market is in an uptrend, downtrend, or consolidation.

2. Key Level Validation: When the price reaches a key support or resistance level, pay close attention to the volume.

3. Breakout Confirmation: If the price attempts to break through a long-term resistance level, it must be accompanied by significant volume. Simply put, 'a breakout without volume is a fakeout.' Only a breakout with high volume signifies that major players have committed real capital to capture that level.

Learning to analyze volume isn't about predicting whether the price will rise or fall tomorrow, but about assessing the 'credibility' of the current trend. In this field full of uncertainty, by choosing well-known and regulated platforms for observation and learning, and combining it with the 'volume precedes price' mindset, you will find that the once-boring candlestick charts begin to read like a novel with a plot, where every bar tells you a story about where the money is going.
