Volume Indicator on TradingView Explained

The previous lesson covered ATR, a pure measure of volatility. This lesson closes out Module 5 with a different kind of measurement entirely: Volume - how much trading activity backed a given price move.

What the Volume Indicator Shows

The Volume indicator plots the number of shares (for stocks) or contracts (for Futures and Options) traded during each period, as a histogram below the price chart. Taller bars mean more trading activity during that period; shorter bars mean less.

Why Volume Is Used to Help Confirm a Price Move

A price move accompanied by noticeably higher-than-average volume is commonly viewed by many traders as more significant than a similar-looking move that occurred on unusually thin, low volume. The reasoning: a move with a large number of participants actively trading behind it is often treated as reflecting more genuine conviction than the same-looking move happening quietly, with relatively few shares or contracts changing hands.

What a Volume Spike Suggests - and What It Doesn’t

A volume spike - a bar noticeably taller than recent surrounding bars - is often watched as a sign that something significant may be happening at that moment. It’s worth being precise about the limits of this, though: volume describes how much activity occurred, not which direction price goes next. A spike can accompany a strong breakout, a sharp reversal, or simply a burst of short-lived, indecisive activity - volume alone doesn’t distinguish between these outcomes.

Combining Volume With This Module’s Other Indicators

Volume is rarely used entirely on its own - many traders check it alongside another signal from earlier in this module. For example:

• An RSI (Lesson 21) reading crossing into overbought/oversold territory, alongside a volume spike, is often treated as more noteworthy than the RSI reading alone.
• A MACD (Lesson 22) crossover accompanied by rising volume is commonly viewed with more attention than the same crossover on quiet, low volume.

Real-Life Example: Confirming a Breakout

Suppose a stock has been consolidating inside a rectangle (Lesson 16) for several weeks, then breaks cleanly above the top boundary. A trader checks the Volume panel at the moment of that breakout and sees a noticeably tall bar, well above the recent average. This volume confirmation adds to the trader’s overall read that the breakout may reflect genuine conviction, rather than a low-volume move that could reverse just as quickly - though, as with every indicator in this module, it’s one input, not a certainty.

Analogy: A Crowded vs Empty Room

Think of volume like the difference between a decision made in a packed, crowded room full of active discussion, versus the same decision made quietly by one or two people in an empty room. Both might arrive at the same outcome, but the crowded room’s decision often carries a different sense of weight and conviction, simply because of how much broader activity surrounded it - exactly the intuition many traders apply when checking volume alongside a price move.

Module 5 Recap: The Eight Indicators Covered

This module opened with Lesson 18’s foundational overlay-versus-oscillator distinction, then worked through:

1. EMA and SMA (Lesson 19) - two flavours of moving average
2. VWAP (Lesson 20) - an intraday, volume-weighted average price
3. RSI (Lesson 21) - a momentum oscillator
4. MACD (Lesson 22) - a trend and momentum indicator
5. Bollinger Bands (Lesson 23) - a volatility-based band
6. SuperTrend (Lesson 24) - a trend-following overlay
7. ATR (Lesson 25) - a pure volatility measurement
8. Volume (this lesson) - trading activity, used to help confirm a move’s significance

Common Beginner Mistakes

• Treating a volume spike as a guaranteed directional signal. It confirms activity, not which way price goes next.
• Ignoring volume entirely when reading a chart. Even a basic glance at whether a move looks “busy” or “quiet” adds useful context.
• Trying to master and combine all eight of this module’s indicators at once. Most traders build comfort with one or two before layering in more.
• Forgetting that volume, like every indicator in this module, describes the past and present - never a guaranteed future outcome.

Practical Tips

• Get in the habit of glancing at the volume panel whenever reviewing a notable price move, simply asking “was this busy or quiet?”
• Pick one or two indicators from this module to practice combining with volume, rather than trying to layer in all eight simultaneously.
• Carry the overlay-versus-oscillator distinction, and this module’s full set of eight indicators, forward into the rest of this course - later modules build on this foundation directly.

Conclusion

Volume closes out this module's tour of trend, momentum, volatility, and volume-based indicators - eight tools in total, each describing a different aspect of price and activity, none of them a standalone guarantee of what happens next. With this foundation in place, the next module shifts to a more organizational skill: building and maintaining watchlists.
