Module 1 · Why Volume Profile
What a Volume Profile Is
A histogram of volume traded at each price — and 'volume is votes'.
In this lesson you'll
- Define a volume profile precisely
- Understand 'volume = votes' (two participants agreeing)
- Distinguish wide bars (participation) from narrow bars
Every transaction requires two participants agreeing on a price — a buyer and a seller. So you can think of each unit of volume as a vote for “this price is fair.” Where votes pile up (wide bars), the market strongly agreed. Where there are few votes (narrow bars), it didn't.
Platforms can assign a bar's volume to price rows in different ways. The most accurate (“distribute across high–low”) spreads each bar's volume across all the prices it covered; a simpler method dumps it all at the close. The choice slightly shifts the POC and value area — know which your platform uses.
Key takeaways
- A volume profile = a histogram of volume traded at each price.
- It is price-based (vertical), not time-based (horizontal).
- Volume = votes: every contract is two participants agreeing on price.
- Volume-distribution settings slightly change the profile — know your platform's.

Why that's off: It's a metaphor for agreement via transactions, not literal voting.
Why that's off: Volume marks agreement/acceptance, not a directional forecast.
Why that's off: Exchanges report traded volume, not 'votes'.
Each trade requires a buyer and seller to agree on a price. Volume clustering at a level therefore marks strong agreement that the price was fair.
Why that's off: Both can be 'correct' under different, valid distribution settings.
Why that's off: Time zone affects session boundaries, not the within-session distribution method here.
Why that's off: It's deterministic from the data and the chosen method.
How each platform assigns a bar's volume to price rows (spread across the bar vs dumped at one price) shifts the histogram and can move the POC/value area slightly.
