Quick summary

  • Demand & supply zones are support and resistance from areas where a lot of buying or selling built up · price entering a demand zone is likely to rise · entering a supply zone is likely to fall
  • A sideways range (base) that is broken upward = demand zone (RBR, DBR) · broken downward = supply zone (DBD, RBD)
  • In an uptrend, BUY when price comes down to test a demand zone, SL below the zone · in a downtrend, SELL when price rises to test a supply zone, SL above the zone
  • A broken zone flips its role: demand broken down → supply · supply broken up → demand
  • An order block uses a single candle before a strong break (body + wick) as support or resistance. See examples in section 05

01Demand & Supply

What are demand & supply zones?

Demand & supply zones are a type of support and resistance that comes from areas where a lot of buying or selling built up in the past. When price comes back to test one of these zones, it often makes a significant move.

When price enters a demand zone (a buying zone), it is likely to move up · when price enters a supply zone (a selling zone), it is likely to move down
DEMAND

Sideways range broken upward = demand zone

When price moves sideways in a cluster, it shows hesitation and a fight between buyers and sellers. If price finally breaks out above the range = buyers win, and that sideways range becomes a demand zone straight away.

A demand zone is a sideways range that price breaks above; buyers beat sellers, so when price comes back to test the zone it is likely to rise

SUPPLY

Sideways range broken downward = supply zone

If price breaks out below the sideways range = sellers win, and that range becomes a supply zone straight away. When price comes back up to test it, it is likely to be pushed down.

A supply zone is a sideways range that price breaks below; sellers beat buyers, so when price comes back to test the zone it is likely to fall

Some traders call demand and supply zones the footprints left by big players. Whether or not that is true, these zones are very useful for reading charts and finding entries with an edge · See how to draw a sideways range (base) in EP2 How to trade a sideway market

02Demand Zone

What a demand zone looks like and its types

When price comes back to test a demand zone, there is a good chance it is pushed up. There are 2 types of demand zone:

TYPE 1 · RBR

Rally Base Rally (RBR)

Rally ↑→Base ▭→Rally ↑

Price rises first (rally), pauses to form a sideways range (base), then breaks out and keeps rising (rally) · the demand zone is the sideways range

TYPE 2 · DBR

Drop Base Rally (DBR)

Drop ↓→Base ▭→Rally ↑

Price falls first (drop), pauses to form a sideways range (base), then breaks out and rises (rally) · the demand zone is the sideways range

Demand zone types: Rally Base Rally (RBR) and Drop Base Rally (DBR), using the sideways base as the buying zone
2 demand zone types: top RBR · bottom DBR · tap to enlarge

Using a demand zone on a real chart → BUY with the trend

Blue/black box = demand zone

The gold chart (XAUUSD) on H1 is in an uptrend, with an RBR demand zone below price (the black box in the top image). When price comes down to test the demand zone, whether at the edge, the middle or the far side of the zone, you can BUY with the trend straight away, with your SL below the demand zone you used for the entry.

In the bottom image, price quickly rose to a new high with the uptrend.

Demand zone example on the gold chart XAUUSD H1: in an uptrend price tests an RBR demand zone, BUY with the SL below the zone, then a new high

Before trading demand and supply zones, get comfortable reading the trend first, because trading with the trend improves your chances · Review how to read trends in EP1 What is a trend

03Supply Zone

What a supply zone looks like and its types

When price comes back to test a supply zone, there is a good chance it is pushed down. There are 2 types of supply zone:

TYPE 1 · DBD

Drop Base Drop (DBD)

Drop ↓→Base ▭→Drop ↓

Price falls first (drop), pauses to form a sideways range (base), then breaks out and keeps falling (drop) · the supply zone is the sideways range

TYPE 2 · RBD

Rally Base Drop (RBD)

Rally ↑→Base ▭→Drop ↓

Price rises first (rally), pauses to form a sideways range (base), then breaks out and falls (drop) · the supply zone is the sideways range

Supply zone types: Drop Base Drop (DBD) and Rally Base Drop (RBD), using the sideways base as the selling zone
2 supply zone types: top DBD · bottom RBD · tap to enlarge

Using a supply zone on a real chart → SELL with the trend

Pink/purple box = supply zone

The gold chart (XAUUSD) on H1 is in a downtrend, with an RBD supply zone just above price (the lowest purple box in the top image). When price rises to test the supply zone, whether at the edge, the middle or the far side of the zone, you can SELL with the trend straight away, with your SL above the supply zone you used for the entry.

In the bottom image, price quickly fell to a new low with the downtrend.

Supply zone example on the gold chart XAUUSD H1: in a downtrend price tests an RBD supply zone, SELL with the SL above the zone, then a new low
XAUUSD H1: supply zone (RBD) test → SELL, SL above the zone → new low · tap to enlarge

Never forget that trading demand and supply zones only works once you can read the trend · in an uptrend, focus on BUY at demand zones · in a downtrend, focus on SELL at supply zones

04Zone Flip

Demand & supply zone role reversal

Demand and supply zones can switch roles when price breaks through them.

1
Demand zone broken – when price breaks below the demand zone, it turns into a supply zone straight away
2
Supply zone broken – when price breaks above the supply zone, it turns into a demand zone straight away
Demand and supply zone role reversal: a demand zone broken downward becomes a supply zone, and a supply zone broken upward becomes a demand zone
Role reversal: demand broken down → supply · supply broken up → demand · tap to enlarge

Role reversal on a real chart

On this H1 gold chart, a supply zone acting as resistance is broken to the upside, so the zone becomes a demand zone straight away. When price comes back down to test it, buyers are likely to push it higher.

05Order Block

What is an order block (OB)?

An order block (OB) is a type of support and resistance from an area where a lot of buying or selling built up in the past, just like a demand or supply zone, but it looks different.

An order block uses just a single candle to mark the zone · a demand & supply zone uses the whole sideways range
BULLISH OB

Bullish order block = support

1
Find the candle – the candle just before price breaks up strongly
2
Mark the zone – cover both the candle body and wick as a support zone
3
BUY on the test – when price comes back down to test it, leftover buying is likely to push it up · SL below the zone
Bullish order block: the candle before price breaks up strongly, marked over its body and wick as a support zone; price comes back to test it and rises
Bullish OB (purple box): support from the candle before a strong break up · tap to enlarge
BEARISH OB

Bearish order block = resistance

1
Find the candle – the candle just before price breaks down strongly
2
Mark the zone – cover both the candle body and wick as a resistance zone
3
SELL on the test – when price comes back up to test it, leftover selling is likely to push it down · SL above the zone
Bearish order block: the candle before price breaks down strongly, marked over its body and wick as a resistance zone; price comes back to test it and falls

The key to trading demand & supply zones: read the trend first, then pick zones on the same side as the trend (demand zones in an uptrend · supply zones in a downtrend), enter when price comes back to test the zone, and always place your SL outside the zone. Order blocks follow the same idea, but the zone is drawn from a single candle.

How many types of supply zone are there?

There are 2: Drop Base Drop (DBD), where price falls, pauses sideways, then breaks down again, and Rally Base Drop (RBD), where price rises, pauses sideways, then breaks down. Both use the sideways range (base) as the supply zone.
