Volume Analysis

In one line: Volume tells you how many people believe in a price move, so it confirms strong moves and warns you about weak ones.

📘 Key concepts

What is volume?

Volume is the crowd behind the price. It is shown as bars under the price chart.

Volume — the number of shares (or contracts) traded in a set time (one day, one hour, or one candle).
Each bar shows how much trading happened in that period.
A tall bar = many people trading. A short bar = few people trading.
Think of a bazaar (market). A loud, crowded shop shows real demand. An empty shop is quiet, even if the price tag looks big.
Volume is conviction (how strongly people believe) and fuel (energy behind the move).

High volume confirms, low volume warns

Price alone can lie. Volume tells you if the move is real.

Breakout — when price moves past a clear level (a resistance line it kept failing to cross).
A breakout on high volume is more trustworthy. Many buyers pushed it up. The move has fuel.
A breakout on low volume is suspect. Few buyers. It often fails and falls back — this is a "fakeout".
A strong, healthy trend usually has healthy volume along the way.
Like a cricket team chasing a target: a big, roaring crowd (high volume) shows real momentum; an empty stadium (low volume) feels weak.

Read price and volume together

The pattern between them gives a clear message.

Rising price + rising volume = healthy uptrend. More buyers keep joining. Good sign.
Rising price + falling volume = warning. Price still goes up, but fewer buyers each day. The move is running out of fuel. It may soon stall or reverse.
Falling price + high volume = strong selling pressure. Sellers are serious.
A volume spike (a very tall bar, much bigger than usual) after a long, big move can mark a climax (exhaustion — everyone who wanted in has already jumped in). This can lead to a reversal (the trend turning the other way).

VWAP in one glance

A simple tool for people who trade within one day.

VWAP (Volume Weighted Average Price) — the average price for the day, but weighted by volume, so busy price levels count more.
It acts like a "fair value" line for the day.
Rough idea: price above VWAP = buyers in control; price below = sellers in control.
You do not need to master it now. Just know the name.

🔍 Example

Two stocks both break above ₹100 resistance today. Watch the volume.

 Stock A (real)        Stock B (fake)
 price: 100 -> 105     price: 100 -> 105
 volume bar:  █████    volume bar:  █
 (huge green bar)      (tiny bar)

Stock A: breaks ₹100 with a big green volume bar. Many buyers agree. The breakout has fuel and is more likely to hold.
Stock B: breaks ₹100 but on a tiny bar. Almost no one is buying. This move is weak and often falls back below ₹100 — a fakeout that traps buyers.
Lesson: same price move, very different meaning. The volume bar told the truth.

⚠️ Common mistakes

Looking only at price and ignoring the volume bars below the chart.
Trusting a breakout on low volume — these fail often and trap you.
Thinking any single tall bar always means "buy" — a spike can also mark a top (exhaustion).
Ignoring the warning when price rises but volume keeps falling day after day.
Comparing volume to nothing. Always compare to the recent average, not to one random day.

✅ Key takeaways

Volume = how many people traded — the conviction and fuel behind a move.
High volume confirms a move; low volume makes it suspect.
Rising price + rising volume = healthy; rising price + falling volume = warning.
A huge spike after a long move can mean a climax and possible reversal.
Always glance at volume before trusting a breakout or trend.

📝 Quick check

Q: A stock breaks its resistance but on very low volume. Is this move strong or weak? A: Weak and suspect. Low volume breakouts often fail (a fakeout). Wait for higher volume to trust it.
Q: Price keeps rising but volume keeps falling. What does this warn you about? A: The uptrend is losing fuel. Fewer buyers each day, so the move may stall or reverse soon.
Q: What does a healthy uptrend usually look like in price and volume? A: Rising price with rising (or steady, healthy) volume — more buyers keep joining the move.

Volume — the number of shares or contracts traded in a set period, shown as bars under the chart.
Breakout — when price pushes past a clear level it struggled to cross before.
Fakeout — a breakout that fails and quickly reverses, often on low volume.
Volume spike — a bar much taller than the recent average, meaning sudden heavy trading.
Climax / exhaustion — a burst of very high volume after a long move, when buyers or sellers are used up, often before a reversal.
Reversal — when the trend turns and price starts moving the other way.
VWAP (Volume Weighted Average Price) — the day's average price weighted by volume, used as an intraday fair-value line.
