The importance of volume

The importance of volume

Why do professional traders pay so much attention to the trading volume? What is behind the Volume indicator? Why is the volume analysis important? We will try to answer these questions in this article in the popular-scientific form.

If you have never used the volume, you would, most probably, wish to try to include it into your trading system. You will definitely have some ideas on how to improve your efficiency after you read this article.

The first steps of beginner traders in the financial markets:

  1. registration with a Forex broker;
  2. opening a demo or real account;
  3. downloading a terminal – MetaTrader or Quik.

Then they start experimenting with strategies, looking for Grails and ‘walking on rakes’. Beginner traders fail to make a big profit fast, despite advertising promises of brokerage agencies, and they become disappointed. Their efforts to win back the growing losses by increasing the stakes result in blowing up the account.

A familiar story, yeah?

Many outsiders leave the market soon after just starting their careers. The most motivated and persistent ones try to find out where the trouble lies. Thus, looking for truth, traders start to pay attention to the Volume indicator. What is it about?


The absolute majority of the technical analysis indicators (MA, MACD, Stoch, RSI, BBands, CCI and hundreds of others) use previous price values in their calculations.

Indicators based on price values

The picture above shows examples of indicators based on price values (screenshot from MetaTrader).

The Volume indicator is a completely different story. The specific feature of volumes is that they do not use the price and are not its derivative. Volumes do not pass through formulas and are delivered to the terminal:

  1. in tick terms (each tick represents 1 executed trade), or
  2. in absolute terms (a number of executed trades), or
  3. in money terms (a sum of the costs of executed trades).

The first volume type – tick volume – is well-known mostly to MetaTrader users. The volumes in the absolute and money terms are real volumes of the trades, which are provided by official exchanges in real time.

The clients of Forex brokers, who trade through MetaTrader, often ask whether it is possible to use the tick volume as an alternative of the real one. In principle, the tick volume could be used for the analysis of trades, since both tick and real volumes show the market ACTIVITY.

However, the use of real volumes provides a more accurate analysis.


Look at the picture below. It is a graphical interpretation of the Law of Demand and Supply. Perhaps, you saw such a chart when you were a senior student at a high school or junior student at a higher economic school.

The Law of Demand and Supply

It seems like a very simple picture for beginner theoretical economists.

  • Blue line is the Demand curve.
  • Red line is the Supply curve.
  • Intersection of the curves is the Equilibrium point or fair price.
  • Price is the price axis.
  • Quantity is the axis of a number of bought/sold commodities/services.

However, this simple picture is meaningful. Dependencies of Demand (a wish and readiness to buy) and Supply (a wish and readiness to sell) are a cornerstone and sacred truth, which is the foundation of any commercial trading, including trading on the exchange.

A reader of the article called Volume Analysis may ask: “What has the volume indicator to do with it?” Just look at the Quantity axis. In fact, it shows the value of trading ACTIVITY, which is transmitted through the volume indicator.

While the picture above is a two-dimensional projection of the demand and supply interaction, the typical chart of an exchange trader is a three-dimensional projection, since the Time axis is added to Price and Quantity.

The exchange chart with the volume indicator

Thus, the exchange trading chart shows changes in the:

  1. price
  2. and trading volume
  3. in time.

And now we have a fertile ground for analysis of the demand and supply dynamics based on the interaction of the values of price and volume in time.


The idea of the trading volume analysis is reduced to the search for the most probable answers to the following questions:

  • Why did the price move up (down) and the volume increased (decreased)?
  • How much did the volume increased (decreased) when the price went up (down)?
  • Why does the volume increase and the price doesn’t move?
  • How did the delta (the difference between buys and sells) change?
  • How did the price behave when an abnormal volume emerged?
  • What happened after an abnormal volume emerged?
  • and so on.

Thus, analyzing the volume and its interrelations with the price, a trader forms his own opinion about the change of the demand and supply balance. Figuratively speaking, he ‘reads’ the dynamics of confrontation between buyers and sellers from the chart in real time.

Consequently, well founded trading ideas are developed.

For example:

  • The price grows slowly on falling volumes to the resistance level. The strength of buys is exhausted. It is a deficit of demandA signal for selling since the current price is, most probably, higher than the fair one.
  • The price falls slowly on falling volumes to the support level. The pressure of sells ‘dries out’. It is a deficit of supplyA signal for buying since the current price is, most probably, lower than the fair one.
  • The price refuses to grow despite a big volume of buys. It means that a major player sells out the asset using sell limit orders. It is  a signal for selling.

Here we touch the subject of the market rationality. Followers of this theory believe that the current price is always fair and the market automatically takes into account all factors of influence on the price.


The Wall Street business is financing corporations and selling securities. The public has a comparatively weak understanding of their real value.

Richard Wyckoff

The market prices are formed in the minds of human beings and Errare humanum est (everyone makes mistakes). You will be able to understand that the price is far from being fair in the pivot extreme points if you study price and volume charts, especially the moments of buying and selling climax patterns.

Splashes of volumes on the exchange are often accompanied with the media activity

Abnormal splashes of volumes on the exchange are often accompanied with media activity. The current price, most probably, moves far away from the fair one at such moments. The picture above shows:

  1. The buying climax in the bitcoin market in December 2017 when the price quote reached USD 20 thousand per one coin.
  2. The recent buying climax at the end of June 2019 when they asked USD 13 thousand per one coin.

You can find more examples of situations when the current market price may differ from the real asset value in ‘Extraordinary Popular Delusions and the Madness of Crowds’ by Charles Mackay (by the way, the favourite book of the greatest speculator Jesse Livermore).


Note that a trader who analyzes the volume doesn’t have to consider fundamental factors, track expert forecasts and process other additional sources. All the necessary information is already in the chart: time, price and volume.

This is the advantage of the volume analysis – the chart is a sufficient source for making conclusions regarding the forces of demand and supply and it provides all the necessary information in the form convenient for analysis. And it matters not what the motives are behind the actions of buyers and sellers – intersection of moving averages, deficit of demand in the overbought area, Trump’s tweet or ‘unexpected’ Flash Crash.

If a chart reader correctly interprets interaction of price and volume in time, he acquires the ability to act in harmony with strong players who rarely make mistakes. Major insiders already performed a correct fundamental analysis and their actions in the market (you can track them in the chart by volume splashes) lift the veil on their true intentions. The price and volume chart allows to do it. Let’s consider an example.


We already mentioned above the buying climax at the end of June 2019. Let’s analyze trading volumes at that period. Below is the footprint (what footprint is) from the BitMEX exchange with a 1D period.

Volume analysis in the cryptocurrency market
  1. The buying climax day. Surely it was accompanied with an avalanche of positive news in mainstream media. Note the buyers activity (massive green clusters) when the level of 12,500 was broken. If those green clusters were a true demand strength, why did then the bitcoin roll down so low in the next few days?
  2. July 10. Test of the level of 12,500. Note the clusters. There are ‘greenish’ buyers in a trap (these are traces of the stop-loss activation). The main candle body consists of red clusters, which means the sellers pressure.

Having compared facts in the price and volume chart, an analyst can make a conclusion that the market is not interested to move higher. It means that we should expect downward movement.

He can find a good entry point using the Smart DOM or Smart Tape data. This is how trading on facts is carried out.
