DOM & Level 2 Data Reading — Complete Guide

What is DOM (Depth of Market)?

The Depth of Market (DOM), also known as Level 2, the Order Book, or the Ladder, shows all pending limit orders at each price level in real-time. It's the closest you can get to seeing institutional intent before price moves.

DOM Structure

PRICE    |  BID (Buy Limits)  |  ASK (Sell Limits)
---------|--------------------|-----------------
1.0955   |                    |  450 contracts
1.0954   |                    |  320 contracts
1.0953   |                    |  180 contracts  ← Best Ask
1.0952   |  220 contracts     |                 ← Best Bid
1.0951   |  380 contracts     |
1.0950   |  850 contracts     |                 ← Large support
1.0949   |  290 contracts     |

Reading the DOM

Key Observations

1. Thick levels: Large order clusters = potential support/resistance
2. Thin levels: Few orders = price can move through quickly
3. Refreshing orders: Orders that keep appearing = institutional algo
4. Pulling orders: Orders disappearing before being hit = spoofing

Bid/Ask Imbalance

• More bids than asks = bullish pressure building
• More asks than bids = bearish pressure building
• Sudden disappearance of one side = imminent move

DOM Trading Patterns

1. Absorption

When a large limit order "absorbs" aggressive orders without price moving:

Scenario: 500-lot limit buy at 1.0950
- Market sellers hit it: 100 lots... 200 lots... 300 lots...
- Price STAYS at 1.0950 (the limit order absorbs selling)
- Eventually sellers exhaust → price bounces UP

Interpretation: Strong institutional buyer at that level

2. Iceberg Orders

Large orders hidden as small visible quantities:

Visible: 10 lots at 1.0950
Reality: 500 lots total, showing only 10 at a time
Sign: The same level keeps "refreshing" after being hit

3. Spoofing / Layering

Fake orders placed to manipulate perception:

Spoofer places 1000 lots on bid side (looks like strong support)
Retail/algos see this and buy
Spoofer cancels bids AND sells into the buying
Price drops — spoofer profits

4. Stacking

Multiple limit orders placed in sequence to create a "wall":

1.0960: 200 lots
1.0959: 200 lots
1.0958: 200 lots
1.0957: 200 lots  ← "Stacked" sell wall

This creates resistance. If price breaks through = strong signal.

DOM Trading Rules

For Scalping

1. Identify levels with unusual order size (3x+ average)
2. Watch if aggressive orders can break through
3. If absorbed → fade the aggressor
4. If broken → join the breakout

For Confirmation

1. Have your SMC/ICT bias first (HTF direction)
2. Drop to DOM at your entry level
3. Confirm institutional presence (absorption, iceberg, stacking)
4. Enter with confidence when DOM confirms

DOM Limitations

• Only shows LIMIT orders — market orders are invisible until executed
• Orders can be cancelled — what you see may not execute
• Crypto DOM is fragmented — multiple exchanges = incomplete picture
• Speed required — DOM changes in milliseconds
• Not suitable for swing trading — short-term tool only
