Lesson 6: Reading Volume

📘 Day Trading in 5 Minutes · Lesson 6 of 10

In Lesson 5 you learned to read the direction of a chart from its highs and lows. This lesson adds the conviction behind that direction. Volume tells you how much real money is backing a move, and it is the difference between a price change you can trust and one that is about to fizzle.

What Volume Is

Volume is the number of shares traded during a given bar. On most charts it shows up as the row of vertical bars along the bottom, one under each candle. A tall bar means a lot of shares changed hands. A short bar means few did.

Price tells you what happened. Volume tells you how many people cared. A one percent move on huge volume means a crowd agreed on the new price. The same move on tiny volume means almost nobody was involved, so it carries far less weight.

Why It Confirms or Warns

The core idea is simple: strong moves should come with strong volume. When price makes a big push and the volume bar towers over the recent ones, real buyers or sellers are driving it. That move has fuel behind it, and it tends to continue.

When price makes a big push but volume stays thin, treat it as a warning. The move lacks participation, which means it can reverse the moment the few traders involved change their minds. A rally nobody is buying is a rally that usually fades.

Breakouts Versus Pullbacks

This is where volume earns its keep for a day trader. The same chart event means very different things depending on the volume.

On a breakout, when price clears a resistance level you marked back in Lesson 4, you want to see volume surge. A breakout on heavy volume says demand is real and the level broke for a reason. A breakout on light volume is the classic trap, often called a false breakout, where price pokes above the level and then sinks right back in.

On a pullback, you want the opposite. When a stock in an uptrend dips back toward support, light volume on that dip is healthy. It means sellers are not aggressive, just a few traders taking profit. If volume swells on the pullback instead, that is a sign real selling has arrived, and the trend may be in trouble.

The Dry-Up Before a Move

One of the most useful volume signals is quiet. When a stock has been consolidating and volume slowly fades to almost nothing, it often means the sellers are exhausted and the stock is coiling for its next move. Traders call this a volume dry-up.

Think of it as pressure building. Activity dries up, the range tightens, and then a single high-volume bar breaks the stock out of its sleepy range. That shift from very quiet to suddenly loud is one of the cleaner cues that a move is starting. Watch for the calm, then act when the volume returns.

Next up

You now have the four building blocks: candles, timeframes, levels, trend, and the volume that confirms them. Lesson 7 puts them together into the chart patterns that actually matter, the recurring shapes that signal where price is likely headed.
