Live Bookmap DOM Liquidity Heatmap

Live Bookmap DOM Liquidity Heatmap is a real-time market-analysis tool that visually shows where buy and sell orders are sitting in the order book and how that liquidity changes over time.

In simple terms:

It is a live map showing where traders have placed visible limit orders around the current price.

What is DOM?

DOM = Depth of Market.

The DOM displays the available buy and sell orders at different prices.

Example:

Price	Side	Visible Liquidity
$102,000	Sell	1,800
$101,500	Sell	3,500
$101,000	Sell	1,100
$100,000	Current Price	—
$99,500	Buy	2,400
$99,000	Buy	5,700

The large orders around $101,500 and $99,000 are potential liquidity zones.

What is the heatmap?

Instead of displaying only numbers, a heatmap represents the size of orders visually.

For example:

PRICE

102,000    ░░░░████
101,500    ░██████████   ← Large sell liquidity
101,000    ░░░████
100,500    ░░░░
100,000    ─── CURRENT PRICE ───
 99,500    ░░████
 99,000    ███████████  ← Large buy liquidity
 98,500    ░░░████

The stronger/brighter bands generally represent larger visible resting orders.

Why is it called “Live”?

The visualization continuously updates as:

• New limit orders appear
• Existing orders are cancelled
• Orders move to different prices
• Market orders execute against liquidity
• Bid/ask depth changes
• Price moves through the order book

So you can observe not just where liquidity is, but also how it behaves over time.

What can traders observe?

A live liquidity heatmap can help visualize:

Liquidity walls
Large concentrations of visible buy or sell orders.

Liquidity stacking
Liquidity repeatedly appearing around particular price levels.

Liquidity pulling
Orders disappearing before price reaches them.

Absorption
Large amounts of buying or selling occurring while price moves relatively little.

Liquidity shifts
Large orders moving closer to or farther from the current price.

Market-order activity
Aggressive buying and selling interacting with resting liquidity.

Bookmap vs. ordinary DOM

A traditional DOM might show:

SELL
101.50   3,500
101.25   1,200
101.00   900
---------
100.75   700
100.50   2,400
100.25   5,700
BUY

A Bookmap-style heatmap adds historical time:

Price
  ↑
102 ┃ ░░████████░░░
101 ┃ ░██████████░░
100 ┃ ───── PRICE ─────
 99 ┃ ░░████████░░░
 98 ┃ ███████████░░
    └────────────────→ Time

That makes it possible to see whether liquidity appeared, stayed, moved, or disappeared.

Important limitation

A liquidity heatmap normally shows visible order-book liquidity. It does not necessarily reveal hidden orders or every trader’s intentions.

A large liquidity wall can also be cancelled before execution. Therefore:

Large liquidity ≠ guaranteed support or resistance.

For a finance website
