Supply and Demand ZonesS&D
Supply and demand zones are price areas, drawn as bands rather than lines, where price previously turned sharply because of heavy selling (supply) or buying (demand).
When price leaves an area in a hurry, it often means one side overwhelmed the other there. Supply and demand traders mark those areas as zones and watch what happens when price comes back. It is a framework for reading the chart, not a guarantee.

Zones in plain words
A supply zone is where selling pressure previously overwhelmed buying, so price dropped.1 A demand zone is the reverse and can act as a potential floor, with no guarantee.1
Zones are bands, not lines: support often develops in a price zone rather than at one price.2
They are close cousins of Support and Resistance.
How to draw a zone, step by step
Find a sharp move
Find a sharp move away from an area — large candles, gaps or heavy volume point to a strong imbalance.1
Find the base
Locate the sideways consolidation just before that move.1
Draw the band
Draw the zone from the top to the bottom of the pause before the move.1
Grade the zone
Judge how quickly price left, how strong the move was and whether the zone has been tested.3
Prefer fresh zones
Many traders prefer zones price has not revisited since they formed.1
Plan for failure
Put the stop just beyond the zone, since even a fresh zone can fail the first time it's tested.1
Worked examples
Example 1 — Drawing a demand zone
Demand zone $42–43Price ranges between $42.00 and $43.00 for four bars, then jumps to $48.
| Zone top | $43.00 |
| Zone bottom | $42.00 |
| Zone height | $1.00 |
The zone spans the high and low of the pause before the breakout.1
Example 2 — Trade plan on the return
3:1 planPrice later falls back to $43. You buy there with a stop at $41.50 and a target at $47.50.
| Risk | $43 − $41.50 = $1.50 |
| Reward | $47.50 − $43 = $4.50 |
| Reward:risk | 3:1 |
Demand zones are potential floors with no guarantee of holding, so the stop sits below the zone.1
Example 3 — Zone fails
−$1.50 per sharePrice returns to the zone and closes at $41.20.
| Entry | $43.00 |
| Stop hit | $41.50 |
| Loss | −$1.50 per share |
Even a fresh zone can fail on its first test.1 The stop kept the loss to the planned amount.
Supply zone vs demand zone
| Aspect | Supply zone | Demand zone |
|---|---|---|
| Formed by | Sharp drop from a base | Sharp rally from a base |
| Acts as | Potential ceiling | Potential floor |
| Typical trade | Look to sell on return | Look to buy on return |
| Invalidated by | Close above the zone | Close below the zone |

Floors and ceilings
Beginner
A supply zone formed where sellers overwhelmed buyers; a demand zone is a potential floor.1
Fresh vs tested
Intermediate
Traders often prefer fresh zones not yet revisited, and weigh how strongly price left the area.3
Subjectivity
Advanced
Different traders draw different zones on the same chart, and even fresh ones can break straight away.1 Test your drawing rules with Backtesting.
Common mistakes
Zones too wide
Drawing huge bands that make risk impossible to control.
Trading every zone
Ignoring the trend and zone quality.
No stop
Assuming the zone will hold.
Using stale zones
Trading zones from years ago that no longer matter.
Check your understanding
Test yourself before moving on. Each answer comes with an explanation.
