What Are Iceberg Orders?
Iceberg orders are a sophisticated trading strategy used by investors executing large-volume trades. This approach prevents substantial market impact by automatically splitting a large order into multiple smaller orders. The system executes these smaller orders based on the current best bid/ask prices and the trader's predefined pricing strategy.
Key characteristics:
- Automatically splits large orders into smaller "iceberg tips"
- Replaces orders when previous ones are fully filled or prices deviate significantly
- Minimizes market impact and price slippage
- Preserves anonymity of large trades

How Iceberg Orders Work: A Practical Example
Let's examine a real-world scenario demonstrating iceberg order execution:
Case Study: A trader wants to purchase 1,000 BTC without significantly affecting the market price.
The iceberg order would:
- Split the 1,000 BTC order into smaller portions (e.g., 50 BTC per order)
- Set the order price at: Best Bid Price × (1 - Order Depth)
- Place new orders only after previous ones are fully executed
- Automatically cancel and replace orders if the price moves beyond: Order Depth × 2
Stop execution when:
- Total filled quantity reaches 1,000 BTC
- Market price exceeds the $20,000 "max buy price" threshold
- Resume orders if price drops back below $20,000
Benefits of Using Iceberg Orders
- Reduced Market Impact: Prevents large orders from moving the market against you
- Better Execution Prices: Achieves more favorable average entry prices
- Trade Anonymity: Conceals your full position size from other market participants
- Automated Execution: Removes emotional decision-making during volatile periods

| Parameter | Description | Example Value |
|---|---|---|
