TL;DR: Master volume analysis - the secret indicator that confirms price moves and reveals institutional activity. Add volume indicator to bottom of your chart (usually bar chart).
Step-by-step guide
- Add volume indicator to bottom of your chart (usually bar chart)
- Calculate average volume (most platforms show this automatically)
- Look for volume 2x+ above average - these are significant
- Confirm price moves: uptrend with rising volume = healthy
- Watch for divergence: price rising but volume falling = warning
- At resistance, heavy volume + breakout = likely to continue up

The Concert Crowd: Understanding Volume as Market Enthusiasm
Meet the Visser Family
The Visser family loves attending concerts at the Ziggo Dome in Amsterdam. Father Jan, mother Anna, and daughter Marie have discovered something fascinating: the energy of a concert crowd tells you everything about whether the show will be memorable or forgettable.
Volume in trading works exactly the same way. It measures the crowd enthusiasm behind every price movement.
The Concert Analogy Explained
Imagine two concerts with the same ticket price of fifty euros:
- Concert A: Only 500 people show up (low volume)
- Concert B: 15,000 fans pack the arena (high volume)
Which artist is truly popular? Which show has real momentum? The answer is obvious from the crowd size.
Jan explains to Marie: When the price of a stock goes up, we need to ask the same question. Did 500 shares change hands, or 5 million? The number of shares traded is like counting the fans at a concert.
Volume Spikes: The Standing Ovation Moment
Anna notices something during their favorite band’s performance: when the lead singer hits the famous high note, the entire crowd jumps to their feet, screaming. This is a climax moment with maximum participation.
In trading, a volume spike works identically. When volume suddenly doubles or triples the normal amount, something significant is happening. Big institutions are either rushing to buy or scrambling to sell.
How to Calculate Relative Volume
Marie learns to calculate what traders call Relative Volume. Here is her step-by-step method:
Step 1: Find the average daily volume over the past 20 trading days Example: A stock trades an average of 2,000,000 shares per day
Step 2: Check today’s volume Example: Today, 5,000,000 shares have traded
Step 3: Divide today’s volume by the average 5,000,000 divided by 2,000,000 equals 2.5
This means today’s volume is 250 percent of normal, or 2.5 times the average. This is a significant volume spike that deserves attention.
The Visser Volume Scale
The family creates a simple reference chart:
- Below 0.7 (70 percent of average): Empty concert hall, ignore signals
- 0.7 to 1.3 (70 to 130 percent): Normal attendance, proceed with caution
- 1.5 to 3.0 (150 to 300 percent): Packed venue, signals are reliable
- Above 3.0 (300 percent plus): Standing ovation or mass exodus, expect dramatic moves
Practical Example with Numbers
Jan shows Marie a real calculation:
Stock ABC has traded 8,500,000 shares today. The 20-day average is 3,400,000 shares.
Relative Volume equals 8,500,000 divided by 3,400,000. 8,500,000 divided by 3,400,000 equals 2.5.
This is 250 percent of normal volume. The concert hall is packed. Whatever signal the price gives today carries real conviction behind it.
Volume Confirms Price: Reading the Crowd’s True Feelings
The Honest Crowd Principle
Anna teaches Marie an important lesson: crowds do not lie, but they can be quiet when uncertain. If the price of a stock moves higher, volume tells you whether the crowd genuinely believes in that move.
Four Scenarios the Visser Family Tracks
Scenario 1: Price Rising with Rising Volume (Healthy Uptrend)
Imagine more and more fans joining the concert as the night goes on. The energy builds, the crowd grows, and the excitement is genuine. This is a healthy uptrend.
Jan’s calculation example:
- Monday: Stock closes at 45 euros, volume is 1,200,000 shares
- Tuesday: Stock closes at 47 euros, volume is 1,500,000 shares
- Wednesday: Stock closes at 49 euros, volume is 1,800,000 shares
Each day the price rises AND the crowd grows. This trend has real support.
Scenario 2: Price Rising with Falling Volume (Warning Signal)
Now imagine fewer fans showing up each night even though ticket prices keep increasing. Something is wrong. The promoter might be artificially raising prices while interest fades.
Anna’s calculation example:
- Monday: Stock closes at 45 euros, volume is 2,000,000 shares
- Tuesday: Stock closes at 47 euros, volume is 1,400,000 shares
- Wednesday: Stock closes at 49 euros, volume is 900,000 shares
The price keeps climbing, but volume drops from 2,000,000 to 900,000. That is a 55 percent decrease in participation. The crowd is losing interest. This rally is likely to fail.
Scenario 3: Price Falling with Rising Volume (Panic Selling)
Fans are not just leaving quietly. They are rushing for the exits, pushing and shoving. This is a panic situation.
Marie’s calculation example:
- Stock drops from 50 euros to 45 euros (down 5 euros)
- Normal volume is 1,000,000 shares per day
- Today’s volume is 4,000,000 shares
Relative volume equals 4,000,000 divided by 1,000,000, which equals 4.0.
This is 400 percent of normal. Four times as many people are selling compared to a normal day. Major institutions are dumping shares. More downside likely follows.
Scenario 4: Price Falling with Falling Volume (Exhaustion)
The crowd has already left. Those who wanted to sell have sold. The remaining fans are loyal but few.
Jan explains: When volume dries up during a decline, it often signals the selling is nearly finished. Patient buyers might find opportunities soon.
The Visser Confirmation Rule
Before making any trade, the family asks one simple question:
Does volume confirm the price move?
- If YES (volume supports direction): Consider trading
- If NO (volume contradicts direction): Wait for clarity
Step-by-Step Confirmation Check
Step 1: Note the price direction (up or down) Step 2: Calculate today’s relative volume (today divided by 20-day average) Step 3: Compare to recent days
If price is rising AND volume is rising: Confirmation (bullish) If price is rising AND volume is falling: Divergence (warning) If price is falling AND volume is rising: Confirmation (bearish) If price is falling AND volume is falling: Potential exhaustion (watch closely)
Breakout Validation: When the Crowd Storms the Stage
The VIP Barrier Analogy
At every concert, there is a barrier between the general audience and the VIP section near the stage. Sometimes fans try to push through this barrier. Most attempts fail because not enough people are pushing. But occasionally, when enough fans surge forward together, the barrier gives way.
In trading, a breakout works exactly like this. The price tries to push through a resistance level. Whether it succeeds depends entirely on how many traders participate in the attempt.
The Breakout Checklist
Marie creates a checklist that the Visser family uses for every potential breakout:
Checkbox 1: Price must close above the resistance level Checkbox 2: Volume must be at least 200 percent of the 20-day average Checkbox 3: The candle must close in the top 25 percent of its range
If all three boxes are checked, the breakout is likely real. If any box is unchecked, the breakout is probably false.
Complete Calculation Example
Jan walks Marie through a real scenario:
The Setup: Stock XYZ has resistance at 100 euros. It has tried to break this level three times in the past month and failed each time. The 20-day average volume is 800,000 shares.
The Breakout Day:
- Stock opens at 99 euros
- High of the day is 104 euros
- Low of the day is 98.50 euros
- Stock closes at 103.50 euros
- Today’s volume is 2,100,000 shares
Checking the Boxes:
Checkbox 1: Did price close above 100 euros? 103.50 is greater than 100. YES, confirmed.
Checkbox 2: Is volume at least 200 percent of average? 2,100,000 divided by 800,000 equals 2.625 That is 262.5 percent. YES, confirmed.
Checkbox 3: Did price close in the top 25 percent of the range? Total range equals 104 minus 98.50, which equals 5.50 euros Top 25 percent starts at: 104 minus (5.50 times 0.25) equals 104 minus 1.375 equals 102.625 Did 103.50 close above 102.625? YES, confirmed.
All three boxes are checked. This breakout has strong volume confirmation.
False Breakout Warning Signs
Anna teaches Marie to recognize fake breakouts:
Warning Sign 1: Weak Volume If volume is only 110 percent of average (1.1 times normal), the crowd is not pushing hard enough. The barrier will likely hold.
Warning Sign 2: Poor Close Location If the stock touched 104 but closed at 100.50, it barely held above resistance. This is a weak breakout.
Warning Sign 3: No Follow-Through The next day’s volume should remain elevated. If volume drops back to normal immediately, the breakout may fail.
Volume-Based Entry Strategy
The Visser family uses this simple approach:
- Identify a resistance level that has been tested multiple times
- Wait for a breakout day with volume exceeding 200 percent of average
- Enter on the next day if the stock holds above the breakout level
- Place stop-loss just below the breakout level
- Target profit at 1.5 to 2 times the risk
Example trade calculation:
- Entry at 104 euros (day after breakout)
- Stop-loss at 99 euros (5 euros risk)
- Target at 112 euros (8 euros reward)
- Risk to reward ratio: 8 divided by 5 equals 1.6 to 1
Practice Quiz: Test Your Volume Reading Skills
The Visser Family Challenge
Jan, Anna, and Marie have prepared a quiz to test your understanding of volume analysis. Work through each scenario and calculate the answers before reading the solutions.
Question 1: Relative Volume Calculation
Stock ABC shows the following data:
- 20-day average volume: 1,500,000 shares
- Today’s volume: 4,200,000 shares
Calculate the relative volume. Is this considered high, normal, or low?
Work through it yourself before reading the answer.
Answer: 4,200,000 divided by 1,500,000 equals 2.8 Relative volume is 2.8, or 280 percent of normal. This is HIGH volume (above 1.5 threshold). Signals today are reliable.
Question 2: Volume-Price Divergence
Over three days, you observe:
- Day 1: Price 50 euros, volume 2,000,000
- Day 2: Price 53 euros, volume 1,600,000
- Day 3: Price 56 euros, volume 1,100,000
What is happening? Should you trust this uptrend?
Think about it before reading the answer.
Answer: Price rose from 50 to 56 euros (up 12 percent). But volume dropped from 2,000,000 to 1,100,000 (down 45 percent). This is a volume-price divergence. The crowd is losing enthusiasm even as prices rise. This uptrend is likely to reverse. Do NOT trust it.
Question 3: Breakout Validation
Stock XYZ has resistance at 75 euros. Today’s candle shows:
- Open: 74 euros
- High: 78 euros
- Low: 73.50 euros
- Close: 77.50 euros
- Today’s volume: 900,000 shares
- 20-day average volume: 500,000 shares
Is this breakout valid? Check all three criteria.
Calculate each criterion before reading the answer.
Answer: Criterion 1: Price closed at 77.50, which is above 75. PASS.
Criterion 2: Relative volume equals 900,000 divided by 500,000 equals 1.8 (180 percent). This is below the 200 percent threshold. FAIL.
Criterion 3: Range equals 78 minus 73.50 equals 4.50 euros. Top 25 percent starts at 78 minus (4.50 times 0.25) equals 78 minus 1.125 equals 76.875. Close of 77.50 is above 76.875. PASS.
Result: 2 out of 3 criteria pass. The volume is not strong enough. This breakout has a higher risk of failure. The Visser family would wait for stronger confirmation.
Question 4: Climax Detection
A stock has been rising for 8 days. On day 9:
- Price jumps 9 percent in one day
- Volume is 450 percent of the 20-day average
- The candle has a long upper wick
What is this pattern called? What should you do?
Consider the characteristics before reading the answer.
Answer: This is a climax top (also called a blowoff top). The characteristics match perfectly: huge single-day move, extreme volume (over 300 percent), and a long upper wick showing rejection. The crowd has exhausted itself. Everyone who wanted to buy has already bought. Expect a reversal. Do NOT buy here. If you hold shares, consider taking profits.
The Visser Family Golden Rules
- Always calculate relative volume before trading
- Volume should confirm price direction
- Breakouts need at least 200 percent volume to be reliable
- Extreme volume (over 300 percent) often marks reversals
- Declining volume during a trend signals weakness
Practice these calculations daily until they become automatic. The Visser family checks volume on every trade without exception.
Frequently asked questions
- Why does volume matter if I'm just following price action?
- Volume validates price action. Think of it this way: if a stock jumps 5% on 100,000 shares, it could be one whale manipulating the price. If it jumps 5% on 10 million shares, thousands of traders are participating—that move has conviction and is likely to continue. Price tells you WHAT is happening, volume tells you HOW STRONG it is. Professional traders never trade breakouts, reversals, or trends without volume confirmation. Studies show that breakouts with volume 2x+ above average have a 70% success rate, while low-volume breakouts fail 60% of the time. Volume is the difference between a sustainable move and a fake-out. Always ask: 'Is this price move backed by volume?' If not, skip the trade.
- What volume indicators should I use as a beginner?
- Start with just ONE: VWAP (Volume-Weighted Average Price). It's simple, powerful, and used by institutions. For day trading, buy when price dips below VWAP and crosses back above (institutions buying the dip). For swing trading, only take trades when price is above VWAP (confirms buyers in control). Once you master VWAP (6+ months), add OBV (On-Balance Volume) to spot divergences—when price makes new highs but OBV doesn't, smart money is exiting. Don't overwhelm yourself with 5+ volume indicators. More indicators = more confusion. Professionals use 1-2 max. The best volume indicator is actually just comparing today's volume bar to the 20-day average volume—if it's 150%+ above average on a breakout, that's your green light. Keep it simple until you're consistently profitable.
- How do I know if volume is 'high enough' for a trade?
- Use the 20-day average volume as your benchmark. Here's the rule: (1) For breakouts: volume must be 200%+ of the 20-day average. Anything less, and it's likely a fake-out. (2) For trend continuation: volume should be 120-150% of average. This confirms the trend has fuel. (3) For reversals: look for climax volume—300-500% of average—that exhausts the prior trend. (4) Avoid trading when volume is below 70% of average—low volume = low conviction, signals fail often. You can find 20-day average volume on any charting platform (TradingView, thinkorswim, etc.). Add a simple moving average to your volume bars (20-period SMA) and visually compare. If today's volume bar is touching or exceeding that SMA line by 2x, you have confirmation. Example: if the 20-day average is 5 million shares, a breakout should have 10+ million. That's your objective standard—no guessing.
- What's the difference between relative volume and normal volume?
- Relative volume (RVOL) compares current volume to the average at THIS specific time of day. Normal volume just shows total shares traded. RVOL is more accurate for day trading. Example: It's 10:30 AM. Stock XYZ has traded 2 million shares so far today. Is that high? You don't know until you check RVOL. If the stock normally trades 1 million shares by 10:30 AM, then RVOL = 2.0 (200% of normal). That's high—something unusual is happening. Use RVOL when day trading or scalping—it catches unusual activity early in the day. Use normal volume (compared to 20-day average) when swing trading—you're looking at the full day's volume anyway. Most scanners (Trade Ideas, Finviz, thinkorswim) show RVOL. Look for RVOL > 2.0 on breakout stocks—that means institutions are piling in. RVOL < 1.0 = below-average activity, skip it.
- Can I trade without looking at volume at all?
- Technically yes, but you'll lose money. Here's why: without volume, you can't tell the difference between a real breakout and a fake-out, between strong support and weak support, between institutional accumulation and retail gambling. You're flying blind. It's like driving a car by only looking at the speedometer and ignoring the fuel gauge—you might be going fast, but you don't know when you'll run out of gas. Volume shows you WHO is trading (institutions vs retail) and WHY (conviction vs noise). The most successful traders—Mark Minervini, William O'Neil, Stan Weinstein—all emphasize volume as a critical part of their strategies. O'Neil's CANSLIM system specifically requires 'breakouts on 50%+ above average volume.' If you ignore volume, you'll get trapped in fake breakouts, miss real opportunities, and wonder why your win rate is below 40%. Bottom line: checking volume takes 5 seconds. Not checking it costs you real money. Always check before entering a trade.
