I find that many new people entering the market often overlook an important detail on the chart—that is, what trading volume (vol) is, which I want to share with you today.

Vol (trading volume) simply refers to the total amount of currency that is bought and sold within a certain period of time. For example, if today there are 1,000 BTC traded, that is the vol for that day. It may sound simple, but it’s very important for understanding the true strength behind a price movement.

When you look at the chart, you’ll see colored bars beneath the price chart. What vol means is reflected through these bars—blue bars indicate high buying volume, and red bars indicate high selling volume. An easy way to remember is: blue = more buyers, red = more sellers.

Why should you pay attention to vol? Because it helps you distinguish real movements from fake ones. If the price is rising but the vol is weak, it may just be a temporary trick. On the other hand, when the price rises together with high vol, that’s a sign of a real and strong trend. I also often use vol to spot reversal points—when vol increases sharply at support or resistance levels, it often signals that the price is about to change direction.

Vol is not only an indicator; it’s also the “voice” of the market, telling you what’s happening behind those price numbers. Don’t just look at the price—listen to the voice of vol to understand the market more deeply.
