Supply and demand are the fundamental forces that drive all price movements. Understanding them is essential for any trader.
Basic Concepts
What is Supply?
Definition:
- Amount available for sale
- Sellers in the market
- Willingness to sell
- At various prices
What is Demand?
Definition:
- Amount wanted for purchase
- Buyers in the market
- Willingness to buy
- At various prices
How Prices Move
Basic Principle
Price Movement:
- More buyers than sellers = price rises
- More sellers than buyers = price falls
- Balance = price stays stable
The Auction Process
Markets Work By:
- Buyers bid prices up to find sellers
- Sellers offer prices down to find buyers
- Where they meet = current price
- Imbalance causes movement

Zone Quality
Strong Zones
Characteristics:
- First time tested
- Strong move away
- Little consolidation
- Clear imbalance
Weak Zones
Characteristics:
- Multiple tests
- Slow move away
- Much consolidation
- Less reliable
Fresh vs Used
Fresh Zones:
- Never tested since creation
- Higher probability
- More reliable
Used Zones:
- Previously tested
- May still hold
- Lower probability each test

What to Mark
Zone Boundaries:
- Base of the move
- Small consolidation area
- Not too wide
- Clear edges
Factors Affecting Strength
Timeframe
Higher Timeframe:
- Stronger zones
- More significant
- More reliable
Lower Timeframe:
- Weaker zones
- Less significant
- More easily broken
Strength of Move
Strong Move Away:
- Indicates strong imbalance
- More unfilled orders
- Higher probability return
Weak Move Away:
- Less imbalance
- Fewer unfilled orders
- Lower probability
Time at Zone
Less Time:
- More unfilled orders remain

- Weaker zone
Supply/Demand vs Support/Resistance
Similarities
Both:
- Areas of price reaction
- Potential turning points
- Trading opportunities
Differences
| Supply/Demand | Support/Resistance |
|---|---|
| Origin-focused | Level-focused |
| Zones (areas) | Lines (precise) |
| Unfilled orders concept | Historical reaction |
| Freshness matters | Multiple touches OK |
Practical Application
Creating a Watchlist
Process:
- Mark zones on your charts
- Note zone quality
- Set alerts for price approach
- Prepare trading plan
Entry Strategies
