Module 4: Technical Analysis for Crypto
Volume, the Fuel Behind the Move
Chapter 7 of 16 · about 6 minutes
7.1 Two breakouts
Mint noticed two tokens breaking above resistance on the same day. Both rose about 8%. A week later, one had climbed another 30%. The other had fallen back below where it started.
"They looked identical," said Mint.
"Not quite," said Hash, and pointed to the bars at the bottom of each chart. "The first breakout happened on three times its usual volume. The second happened on barely normal volume. One move had fuel. The other was running on fumes."
7.2 What volume tells you
Volume is the amount of an asset traded during a period. On a daily chart, each volume bar shows how much traded that day. It's usually shown at the bottom of the chart, coloured to match the candle.
Price tells you what happened. Volume tells you how much conviction was behind it. A move on high volume involved many participants and a lot of money. A move on low volume involved few.
Think of an election. A candidate winning with 80% of the vote on a 90% turnout is a strong mandate. The same 80% on a 5% turnout tells you much less about what people really think.
7.3 The basic rules
| Price | Volume | Interpretation |
|---|---|---|
| Rising | Rising | Healthy uptrend with strong participation |
| Rising | Falling | Uptrend losing participation; may be weakening |
| Falling | Rising | Strong selling pressure |
| Falling | Falling | Selling pressure fading; decline may be slowing |
| Breakout above resistance | Well above average | More likely to be genuine |
| Breakout above resistance | Below average | Higher risk of a fakeout |
These aren't laws, but they're useful defaults.
Chapter 7 · Reading price with volume
A two-by-two matrix pairs price rising or falling with volume rising or falling. Price up on high volume signals healthy strength; price down on high volume signals strong selling; moves on low volume in either direction are weaker and less reliable.
7.4 Measuring "high" volume
"High" only means something compared to normal. Many traders compare current volume to the average over a recent period, such as the last 20 days. Charting platforms let you add a volume moving average to make this easy.
| Bitcoin daily volume (illustrative) | |
|---|---|
| 20-day average | 30,000 BTC |
| Breakout day | 75,000 BTC |
| Ratio | 2.5 times average |
A breakout on 2.5 times average volume shows strong participation. A breakout on 0.8 times average is much less convincing.
7.5 Climax volume
Sometimes a long trend ends with an explosion of volume.
A selling climax happens after an extended decline, when panic peaks. Volume spikes enormously, often with a long lower wick, as the last holders give up and buyers absorb everything. It can mark a bottom, at least temporarily.
A buying climax happens after an extended rally, when euphoria peaks. Volume spikes as late buyers rush in and early holders sell to them. It can mark a top.
In crypto, climax volume often coincides with large liquidation cascades, as forced selling or buying piles on top of voluntary trading.
7.6 Volume divergence
When price makes a new high but volume is much lower than at the previous high, it's called a volume divergence. Fewer participants are pushing price higher, which can mean the trend is running out of buyers.
| Price high | Volume at the high | |
|---|---|---|
| First peak | $3,800 | 2.0 million ETH |
| Second peak | $3,950 | 1.1 million ETH |
The price is higher, but participation is much lower. It's a warning sign, not a sell signal on its own.
7.7 Volume profile
Standard volume bars show when trading happened. Volume profile shows at what prices trading happened, displayed as horizontal bars along the price axis.
| Term | Meaning |
|---|---|
| Point of control (POC) | The price level with the most trading in the selected period |
| High-volume node | A price zone with heavy trading, where many traders hold positions |
| Low-volume node | A price zone with little trading, which price tends to move through quickly |
High-volume nodes often act as support or resistance (Chapter 5), because many traders have positions there and react when price returns. Low-volume areas often see fast moves, because there's little interest to slow price down.
7.8 Crypto volume problems
Volume analysis is harder in crypto than in traditional markets, for several reasons.
Fragmentation. Crypto trades on hundreds of venues. A single exchange's volume shows only part of the picture. A breakout may look weak on one exchange and strong across the market.
Fake volume. Some exchanges, particularly smaller or less regulated ones, have been found to inflate their volume through wash trading, where the same party buys and sells to itself. This creates the appearance of activity without real participants. Research by several analytics firms over the years has suggested that a substantial share of reported volume on some venues wasn't genuine.
Spot versus derivatives. Perpetual futures volume is often several times larger than spot volume. Leverage-driven perp volume can tell a different story from spot buying. A rally driven mostly by perps can be more fragile than one driven by spot demand.
Base versus quote volume. Some charts show volume in the asset (for example, BTC), and others in dollars or stablecoins. When price rises sharply, dollar volume rises even if the number of coins traded doesn't. Make sure you know which you're looking at.
Thin tokens. For small tokens, a few large trades, or bots, can dominate volume.
Practical habits:
- Use volume from reputable, high-volume exchanges, or aggregated volume across major venues.
- Compare spot and perp volume when both are available.
- Be skeptical of volume on small tokens and lesser-known exchanges.
- Focus on relative changes, compared to the same source's average, rather than absolute numbers.
7.9 Node's question
"If volume is so unreliable in crypto, why use it at all?" Node asked.
"Because it's still one of the best clues to conviction, when you use clean sources and compare like with like," said Hash. "An unreliable measure you understand is better than ignoring the information entirely. You just weigh it accordingly."
7.10 Try it yourself
Find three breakouts above resistance on the daily Bitcoin chart over the past year. For each, compare the breakout day's volume with the 20-day average volume. Note which breakouts held and which failed.
Then add a volume profile to a three-month chart, if your charting tool supports it. Identify the point of control and one low-volume area, and check how price behaved around them.
Key takeaways from this chapter
- Volume shows conviction behind price moves. High volume means broad participation.
- Rising prices with rising volume are healthy; rising prices with falling volume can signal weakness.
- Compare volume to its recent average. Breakouts on well-above-average volume are more reliable.
- Climax volume can mark exhaustion at the end of long trends.
- Volume profile shows where trading happened by price. High-volume nodes often act as support or resistance.
- Crypto volume is fragmented, sometimes fake, split between spot and derivatives, and can be shown in different units.
- Use clean sources, compare like with like, and treat volume as evidence, not proof.
