What are demand and supply zones, and how do you find them?
A demand zone is a narrow price area where a stock paused briefly and then rallied sharply, suggesting big buy orders. A supply zone is the opposite: a pause before a sharp fall. When price returns to a fresh zone, it often reacts again. Mark the zone from the base candles just before the sharp move.
- Demand zone₹310.15 – ₹314.00Tested on day 45
- Supply zone₹360.90 – ₹363.60Tested on day 69
- Demand zone₹335.40 – ₹338.00Fresh — not tested yet
- 1Drag the time slider to the start, then forward slowly. Watch each zone appear after the sharp move away from its base.
- 2Stop when price comes back to a zone. Did it react the first time?
- 3Turn off supply zones and look only for places where buyers stepped in.
What demand and supply zones are
A sharp move rarely starts from nowhere. Usually price pauses for a day or a few — the base — and then leaves in a hurry. That burst suggests large orders were filled in the base, and some may still be waiting.
- Demand zone: a base followed by a sharp rise. Buyers overwhelmed sellers there.
- Supply zone: a base followed by a sharp fall. Sellers overwhelmed buyers there.
When price comes back to that area, the remaining orders can make it react again. That is the whole idea.
How to identify demand and supply zones
- 1Find a sharp move on the daily chart: several long candles in one direction, clearly bigger than the candles around them.
- 2Look just before it for the base — usually one to three small candles where price went sideways.
- 3For a demand zone, mark from the lowest low of the base up to the top of the base candles' bodies.
- 4For a supply zone, mark from the highest high of the base down to the bottom of the base candles' bodies.
- 5Extend the zone to the right. That's where you wait for price to return.
The sharper the move away and the shorter the base, the stronger the zone tends to be. A slow drift away tells you little.
- Base candles
- Two small days: lows ₹612 and ₹615, body tops ₹620 and ₹621
- Move away
- Three long green days, closing at ₹668
- Zone bottom
- Lowest low of the base: ₹612
- Zone top
- Highest body top of the base: ₹621
- Zone
- ₹612 to ₹621, extended to the right
The zone is ₹9 wide, so a stop just below it keeps the risk small. If price drifts back to ₹621 weeks later, that is where you start paying attention.
Fresh zones and tested zones
A fresh zone is one price hasn't come back to since it formed. A tested zone has been revisited at least once. Each visit fills some of the orders waiting there, so a fresh zone usually deserves more attention than one that has been tested several times.
Use the time slider in the lab above to move the chart forward and watch a fresh zone become a tested one.
The four zone shapes
Traders often name zones by what came before and after the base. The names help you judge strength at a glance.
| Shape | Move in | Move out | What it suggests |
|---|---|---|---|
| Drop-base-rally | Down | Up | A demand zone where a fall was reversed. Reversal zone. |
| Rally-base-rally | Up | Up | A demand zone inside an uptrend. Buyers added more on the pause. |
| Rally-base-drop | Up | Down | A supply zone where a rise was reversed. Reversal zone. |
| Drop-base-drop | Down | Down | A supply zone inside a downtrend. Sellers added more on the pause. |
For swing traders who buy, the rally-base-rally zone in an established uptrend is usually the cleanest setup: you are buying a pause in a move that is already working, not guessing at a turn.
Scoring a zone before you trade it
Not every base is worth a trade. Before you mark a zone as tradeable, run through these questions. The more yes answers, the more attention it deserves.
- 1Strong departure: did price leave the base with long candles, clearly bigger than the ones before?
- 2Short base: is the base one to three candles? A long, messy base tells you less about where the orders sit.
- 3Fresh: has price not come back to it yet?
- 4Trend: does the zone point the same way as the bigger trend on the weekly chart?
- 5Room to run: is the next supply zone far enough above to give at least twice the risk?
- 6Volume: was volume on the departure candles above its recent average?
Treat this as a filter, not a formula. A zone that scores well can still fail. The stop is what keeps a failed zone small.
Ways to enter at a zone
There are two common entries. Both have a cost.
- Limit order at the zone: you place a buy order at the top of the zone and let price come to you, with the stop below the zone. You get the best price, but you take the trade even if price is falling hard into the zone. A GTT order can hold this for you; see GTT orders.
- Wait for a reaction: you let price touch the zone, then buy only after a bullish candle closes, such as a hammer or engulfing candle. You give up some price, and sometimes the move leaves without you, but you skip zones that are being broken.
Beginners usually do better with the second method. It forces you to see buyers return before you commit money.
Common mistakes with zones
- Marking every pause as a zone. Only the base before a sharp, clear move counts.
- Drawing the zone too wide. A wide zone means a wide stop, and that means fewer shares for the same risk.
- Trading zones against the trend. A demand zone in a stock making lower lows on the weekly chart is a weaker idea.
- Re-trading a tested zone again and again. Each visit uses up orders. After two or three tests, a zone often breaks.
- Moving the stop when price enters the zone. The stop below the zone is where the idea is wrong. Leave it there.
Demand zone vs support
| Support | Demand zone | |
|---|---|---|
| Built from | Repeated swing lows | The base before one sharp rally |
| Shape | A line, read as a small zone | A box with a top and a bottom |
| Strongest when | Touched several times | Fresh, with a sharp move away |
| Stop-loss | Below the level | Below the bottom of the zone |
They often overlap, and when they do, the area carries more weight. If you haven't drawn levels before, start with support and resistance.
Planning a trade from a demand zone
- Zone
- ₹300 to ₹306
- Entry
- ₹307, as price returns to the top of the zone
- Stop-loss
- ₹297, below the bottom of the zone
- Risk per share
- ₹10
- Risk you allow
- ₹1,000, so 100 shares
- Target
- ₹327, twice the risk, below the next supply zone
If the zone holds, the target is ₹20 a share away. If price closes through the zone, the stop takes you out for about ₹1,000 plus charges.
Check the numbers with the position size calculator. A zone is also a natural place to look for a confirming candlestick pattern before you enter.

Common questions
Is a demand zone the same as support?
Not quite. Support comes from repeated turning points; a demand zone comes from the base of one sharp rally. They often overlap, and that overlap is worth noting.
Which timeframe should I use to find zones?
The daily chart for swing trading. A zone that also shows on the weekly chart carries more weight.
What if price goes straight through a demand zone?
Then the zone has failed and your stop-loss takes you out. That's why the stop always goes just beyond the zone, decided before you enter.
How wide should a zone be?
As wide as the base candles, no wider. A very wide zone means a wide stop, which means fewer shares for the same risk.
How many times can a demand zone be used?
There's no fixed number. The first return to a fresh zone usually gets the strongest reaction. Each later test fills more of the waiting orders, so the zone weakens.
Do demand and supply zones work for intraday trading?
The idea works on any timeframe, but short-term zones are smaller and break more often. Swing traders mark zones on the daily chart and check the weekly chart for the bigger picture.
What is the difference between a supply zone and resistance?
Resistance comes from several highs at about the same price. A supply zone is the base of one sharp fall. Where they overlap, sellers have shown up in two different ways, so the area deserves respect.
Demand zone kya hota hai?
Woh chhota price area jahan stock thodi der ruka aur phir tezi se upar gaya. Wahan bade buy orders ho sakte hain, isliye price wapas aane par aksar phir react karta hai.
