Supply & Demand Zones

In one line: Price often turns around inside a small area (a zone) where big buyers or big sellers left orders behind — not at one exact line.

🎯 What you'll learn

A demand zone is a price area where buyers were very strong last time.

A supply zone is a price area where sellers were very strong last time.

Think of shopkeepers who all decide "this price is too high, sell now."
On a chart, this shows as a spot where price dropped down fast.
Those sellers may sell again if price returns.
So a supply zone often acts like resistance (a ceiling that pushes price down).

Look for two things together:

A base — a small area where price stays flat and quiet for a few candles (a "candle" is one price bar for a fixed time). This is calm, tight, and narrow.
An explosive move — right after the base, price runs strongly away (up = demand, down = supply).
The base itself is your zone. Draw a box around it (top and bottom of that quiet area).
Big players parked their orders there, then price left in a hurry. That is why it matters.

A fresh (untested) zone has not been touched since price left it. It is the strongest.
Each time price comes back and taps the zone, some orders get used up.
So a zone gets weaker every visit. After 2–3 tests, treat it as tired.
Difference from plain support/resistance: S/R is one line you touch many times; a zone is an area (a box) drawn at the origin of a strong move.

Reliance is trading near ₹1000.

For a few candles it sits quietly between ₹1000 and ₹1010. This is the base.
Then it jumps fast to ₹1080. That fast up-move tells you buyers were strong.
So ₹1000–₹1010 is your demand zone. Draw a box there.

Days later, price falls back down toward ₹1010.

You wait for it to enter the box.
You look for a reversal signal (a sign buyers are stepping in — like a strong green candle bouncing up).
You may buy near ₹1005, and place a stop-loss (an auto-exit if you are wrong) just below the box, say ₹995.
Risk is small (about ₹10), reward can be larger (back toward ₹1080). This is good risk-reward.

₹1080  ┌── strong move up
       │
₹1010 ┌┴┐  ← demand zone (the box)
₹1000 └─┘  base, then price returns to test it

Drawing a huge box. Keep it tight — only the quiet base area.
Buying the moment price nears the zone. Wait for it to enter and show a reversal.
Trusting old, tired zones tested many times.
Ignoring the trend. A zone works better when it agrees with the overall direction.
Skipping the stop-loss. A zone is a probability, not a promise. Price can break through.

Demand zone = strong buyers below = acts like support.
Supply zone = strong sellers above = acts like resistance.
Find a tight base, then a fast move away; the base is the zone.
Fresh zones are strongest; each test weakens them.
Wait for price to return + a reversal, then use a tight stop for good risk-reward.

Q: Price sits flat, then drops sharply. Is that a demand or supply zone? A: A supply zone — the sharp drop shows strong sellers, so it acts like resistance.
Q: Why is a fresh zone stronger than one tested three times? A: Each test uses up some of the waiting orders, so an untested zone still has full strength.
Q: What is the main difference between a zone and a plain support line? A: A zone is an area (a box) at the origin of a strong move; support is a single line that price touches.

Demand zone — a price area with strong waiting buyers; acts like support.
Supply zone — a price area with strong waiting sellers; acts like resistance.
Base — a small, quiet, flat area of candles before a big move.
Candle — one price bar showing movement over a fixed time.
Reversal signal — a chart sign that price may be turning direction.
Stop-loss — an order that auto-exits your trade to limit loss if you are wrong.
Risk-reward — how much you might lose compared to how much you might gain.
