The DOM Buyer vs DOM Seller Fullscreen Chart is the most granular institutional order flow chart inside the Volume Whale Hunter component of the SPX Direction algorithm.
It displays the real-time battle between aggressive buyers and aggressive sellers directly at the Depth of Market (DOM) level. This allows members to see what is happening in real time without having to analyze DOM data.
Unlike:
Candlestick charts
Indicators
Oscillators
Standard volume charts
This chart measures:
Which side is initiating trades
Which side is forcing price movement
Which side has institutional urgency
The chart represents the underlying plumbing of price action itself.
It measures the pressure that causes price to move before the price actually moves.
The Core Concept — Depth of Market (DOM)
DOM stands for Depth of Market:
The live order book
Resting buy orders
Resting sell orders
Active order interaction
There are two types of participants:
Passive Participants
Place limit orders
Wait for fills
Provide liquidity
Aggressive Participants
Use market orders
Lift offers or hit bids
Consume liquidity
Force price movement
Volume Whale Hunter focuses on the aggressive side because aggressive execution is the clearest signal of institutional intent.
What the Two Lines Represent
Green Line — AVG DOM BUYER
Represents:
Aggressive buyers lifting offers
Initiative buying
Buyers willing to pay higher prices immediately
A rising green line means:
Buyers are becoming more aggressive
Institutions are pressing price upward
Buy-side urgency is increasing
Sustained elevation means:
Buyers are committed
This is not random retail flow
Institutions are actively executing
Red Line — AVG DOM SELLER
Represents:
Aggressive sellers hitting bids
Initiative selling
Sellers willing to accept lower prices immediately
A rising red line means:
Sellers are becoming more aggressive
Institutions are pressing price downward
Sell-side urgency is increasing
Sustained elevation means:
Distribution or short pressure is active
Institutions are controlling downside flow
Why This Matters More Than Raw Volume
Traditional volume tells you:
How much traded
DOM chart tells you:
WHO forced the trade
WHICH side initiated
WHO controls the auction
This distinction is critical.
Raw Volume
DOM Chart
Counts transactions
Measures initiative
Includes passive fills
Measures aggressive execution
Shows activity
Shows control
Lagging
Leading
