What Volume Tells You, and What It Does Not

Key takeaway

Volume is a participation count, not a direction. It never tells you which way price is going — only how much agreement was behind the move that already happened.
Two identical candles can mean opposite things. The one nobody traded is not news.
The one correction to the video: forex has no central tape, so the volume on your chart is your broker's tick count, not the market's.

What the bars underneath actually are

One bar = the number of shares that changed hands in that period.

On a daily chart, a bar is that day's traded shares. The colour follows the candle: green means the period closed up, red means it closed down. That is the entire mechanic.

The tallest bar marks the day the most people had to transact. It says nothing about tomorrow — it says a lot about how seriously to take today.

The same candle, twice, meaning different things

A move nobody participated in is a move that costs nothing to reverse.

Identical price gain. On the left, a million shares had to change owners to produce it; on the right, ten thousand did. Only one of these is evidence.

This is why volume is the cheapest filter available to a beginner. It does not require a new indicator or a new theory — it is already on your chart, and it downgrades half the signals you were about to take.

Trend health: loud on the push, quiet on the pullback

In a healthy uptrend, volume expands with the moves up and dries up on the pullbacks.

The pullbacks are people stepping back, not people selling out. When the pattern inverts — heavy pullbacks, thin pushes — the trend is being funded by fewer and fewer participants.

This is the modern version of a very old rule. Dow theory said the same thing a century ago: volume should confirm the trend.

Breakouts: the one place volume earns its keep

A level breaking on ordinary volume is usually not a break. It is a poke.

Two breaks through the same resistance. On the left, a wide candle on volume far above the recent bars. On the right, an average candle on average volume — and a red candle straight back inside.

Look for two things together: a decisive candle and a volume bar clearly taller than its neighbours.
One without the other is a warning, not a signal.
Volume confirms, it does not predict — you get the read after the candle closes, which is the price of the information.

Pair this with support becoming resistance and you have the two questions worth asking about any break: does the level matter, and did anyone show up for it?

The correction: forex volume is not volume

There is no central exchange in forex, so nobody can count the whole market.

The video describes forex volume as the number of currency traded in a period. In practice, what your platform draws is tick volume — how many times the price your broker quoted changed — from that one broker's feed.

Stocks trade on an exchange that records everything. Forex is a network of venues, and your chart sees one of them.

Tick volume still tracks activity well enough that the trend and breakout reads above usually survive. But treat it as a proxy: do not compare it across brokers, and do not build a rule on an exact threshold.

Try this week

Turn the volume indicator on for every chart you look at this week.
Find three breakouts on a daily chart and mark the volume bar on each break — then check what happened next.
Find one trend and check whether the pullback bars are shorter than the push bars.
On a forex chart, note that the number is your broker's ticks and stop comparing it to a stock's.

Common questions

What does volume mean in trading?

The number of units that changed hands in a period — shares for a stock, contracts for a future, coins for a crypto pair. It measures participation, not direction: a green bar means the period closed up, not that buyers outnumbered sellers, since every trade has both.

Is high volume bullish or bearish?

Neither on its own. It amplifies whatever the candle did. High volume on a strong up candle says a lot of people agreed on the move up; the same volume on a sharp down candle says the same thing about the move down.

How do I use volume to spot a fake breakout?

Compare the breakout bar's volume with the recent bars. A break through a level on volume no larger than the last few sessions has the same crowd behind it as the sideways action that preceded it, which is a common way for a break to fail and reverse.

Does volume work in forex?

Partly. Forex has no central exchange, so charts show tick volume from a single broker's feed rather than true traded volume. It correlates with real activity well enough for trend and breakout reads, but it is a proxy and it differs between brokers.

What is a volume divergence?

Price makes a higher high while volume makes a lower high — the new high was reached with fewer participants than the last one. It is a caution flag rather than a signal, and like all divergences it can persist for a long time before anything happens.
