Understanding Order Books: A Visual Guide for Token Founders

If you're launching a token on centralized exchanges, understanding order books is essential. This visual guide will demystify the concepts and help you make informed decisions about your token's market structure.

What is an Order Book?

An order book is a real-time list of all buy and sell orders for a trading pair, organized by price. It's the foundation of price discovery on centralized exchanges.

ℹ️

Think of it like: An auction house where buyers and sellers publicly display their offers, and trades happen when prices match.

Key Concepts Explained

1. Bids and Asks

Term	Meaning	Example
Bid	Buy order price	"I'll buy at $1.02"
Ask	Sell order price	"I'll sell at $1.04"
Best Bid	Highest buy order	$1.02 in example
Best Ask	Lowest sell order	$1.04 in example

2. The Spread

The spread is the gap between the best bid and best ask.

Spread Calculation:
Best Ask: $1.04
Best Bid: $1.02
────────────────
Spread: $0.02 (absolute)
Spread: 1.94% (percentage)

⚠️

Why Spread Matters: Wide spreads cost traders money. A 5% spread means buyers immediately lose 5% of their value. This discourages trading.

Spread Benchmarks

Spread	Quality	Typical For
< 0.1%	Excellent	BTC, ETH on major exchanges
0.1-0.5%	Good	Top 100 tokens
0.5-2%	Acceptable	Mid-cap tokens
2-5%	Poor	Low liquidity tokens
> 5%	Very Poor	New/illiquid tokens

3. Market Depth

Market depth shows how much liquidity exists at each price level.

Depth Visualization:

$1.10 ████                           4,000 tokens
$1.08 ██████                         6,000 tokens
$1.06 ████████████                  12,000 tokens  ASKS
$1.04 ████████████████████          20,000 tokens  (SELL)
───── MID PRICE: $1.03 ─────────────────────────────
$1.02 ████████████████████████████  28,000 tokens  BIDS
$1.00 ████████████████              16,000 tokens  (BUY)
$0.98 ██████████                    10,000 tokens
$0.96 ██████                         6,000 tokens

Why Depth Matters

Depth	Impact
Deep order book	Large trades possible without slippage
Shallow order book	Small trades move price significantly
Balanced depth	Stable, two-way trading
One-sided depth	Price pressure in one direction

Order Types Explained

Market Orders

Execute immediately at the best available price.

Market Buy Example:
You: "Buy 50,000 tokens at market"

Order book eats through asks:
- 20,000 @ $1.04 = $20,800
- 15,000 @ $1.05 = $15,750
- 12,000 @ $1.06 = $12,720
-  3,000 @ $1.07 =  $3,210
────────────────────────────
Total: 50,000 tokens for $52,480
Average price: $1.0496 (slippage!)

ℹ️

Key Insight: Market orders guarantee execution but not price. The larger your order relative to liquidity, the more slippage you'll experience.

Limit Orders

Execute only at your specified price or better.

Limit Order Example:
You: "Buy 50,000 tokens at $1.00"

Your order joins the bid side:
$1.02 │   25,000
$1.01 │   18,000
$1.00 │   65,000 ← Now includes your 50,000

Trade only happens if someone sells at $1.00

Other Order Types

Type	Description	Use Case
Stop Loss	Triggers market order at price	Risk management
Stop Limit	Triggers limit order at price	Precise exits
IOC	Cancel if not immediate	Urgent trades
FOK	Fill completely or cancel	Large precise trades
Post Only	Only maker orders	Avoid taker fees

Impact on Your Token

Scenario 1: Thin Order Book

Problem: Only $50,000 liquidity within 5%

Effect:
- $10,000 buy → 1.5% price impact
- $25,000 buy → 4% price impact
- $50,000 buy → 8% price impact

Result: Whales can't enter, volatility high

Scenario 2: Healthy Order Book

Solution: $500,000 liquidity within 2%

Effect:
- $10,000 buy → 0.15% price impact
- $25,000 buy → 0.4% price impact
- $50,000 buy → 0.8% price impact

Result: Institutional interest possible

Reading Order Book Health

Green Flags

Tight spread (< 1% for your market cap)
Balanced bid/ask depth
Consistent order sizes
Regular order updates
Multiple price levels filled

Red Flags

Wide spread (> 3%)
One-sided depth (buy or sell wall)
Large gaps between prices
Stale orders (no updates)
Only orders at extremes

The Market Maker's Role

Professional market makers maintain healthy order books by:

1. Spread Management

Continuously placing tight bid/ask orders

Market Maker Orders:
BUY:  $1.019, $1.018, $1.017, $1.016, $1.015
SELL: $1.021, $1.022, $1.023, $1.024, $1.025

Spread: Only $0.002 (0.2%)

2. Depth Provision

Maintaining orders at multiple price levels

3. Continuous Updates

Adjusting orders as market moves

4. Inventory Management

Balancing buy/sell to avoid directional risk

ℹ️

Pro Tip: Good market making creates the illusion of natural liquidity. Traders see tight spreads and deep books without knowing a market maker is behind it.

Common Order Book Patterns

Buy Wall

Large buy orders at a specific price level.

$1.00 │ 500,000 tokens ← BUY WALL

Interpretation:
- Strong support at this level
- Could be whale accumulation
- Or market maker floor

Sell Wall

Large sell orders blocking price advance.

$1.50 │ 300,000 tokens ← SELL WALL

Interpretation:
- Resistance at this level
- Could be profit taking
- Or intentional suppression

Spoofing (Illegal)

Fake large orders designed to manipulate.

⚠️

Warning: Spoofing is market manipulation and is illegal on regulated exchanges. Large orders that disappear before execution are a sign of this practice.

Practical Tips for Projects

Conclusion

Understanding order books is fundamental for any token project engaging with centralized exchanges. The concepts of spread, depth, and order flow directly impact your token's tradability and attractiveness to investors.

Key takeaways:

Spread = trading cost (keep it tight)
Depth = capacity for large trades (keep it deep)
Balance = healthy two-way market (keep it even)
Activity = live, updating orders (keep it fresh)

Work with professional market makers to maintain healthy order books, and your token will be positioned for success on centralized exchanges.
