In the fast-moving world of cryptocurrency trading, large orders can significantly impact market prices—especially when they’re fully visible on the order book. Traders seeking discretion and efficiency often turn to advanced order types like iceberg orders to execute sizable trades without tipping their hand. This guide dives deep into what iceberg orders are, how they work, and why they’re a powerful tool for both novice and experienced traders.
Understanding Iceberg Orders
An iceberg order is an algorithmic trading strategy that breaks a large order into smaller, manageable pieces. Only a fraction of the total order—referred to as the "visible portion"—is displayed on the public order book at any given time. As each small segment fills, the system automatically releases another slice, keeping the full size hidden from the broader market.
This method mimics the nature of an iceberg: just as only a small part of an iceberg is visible above water, only a portion of the order is exposed to other traders. The rest remains concealed beneath the surface, reducing the chance of price manipulation or front-running.

How Iceberg Orders Work
The system continuously monitors market conditions and replenishes executed or canceled segments based on predefined settings. Once a small order is fully filled or the price levels shift significantly, the bot evaluates the current market depth and places a new limit order accordingly.
Traders can customize several parameters to align with their execution goals:
- Amount per order: The size of each visible slice.
- Total order amount: The overall quantity to be traded.
- Number of visible orders: How many partial orders appear on the book simultaneously.
- Limit price: A ceiling (for buys) or floor (for sells) that controls when the bot operates.
- Execution preference: Determines how aggressively or passively orders are placed.
These settings give traders granular control over timing, price, and visibility—critical elements when navigating volatile digital asset markets.
Execution Modes: Balancing Speed and Price
When setting up an iceberg order, users choose one of three execution preferences, each designed to meet different trading objectives.
1. Quick Execution
Ideal for traders prioritizing speed, this mode uses a more aggressive approach:
- The first buy order appears at the best ask price.
- Subsequent orders step down toward the bid side.
This increases the likelihood of rapid fills but may sacrifice some price efficiency.
2. Price-Speed Balance
For those seeking a middle ground between cost and execution time:
- The initial buy order is placed midway between the best bid and ask.
- Following orders gradually move deeper into the bid ladder.
This balanced tactic helps avoid slippage while maintaining reasonable fill rates.
3. Passive Queuing (Better Price)
Designed for maximum price optimization:
- Orders are placed deep in the order book, often at or near the best bid.
- This improves average execution price but may result in slower fills.
Best suited for patient traders in stable market conditions.
Why Use Iceberg Orders?
Large market orders can send clear signals about a trader’s intentions—inviting adverse price movements driven by other market participants reacting to the visible demand or supply. Iceberg orders mitigate this risk by:
- Minimizing market impact: By revealing only small portions of the total order, they prevent sudden spikes or drops in price.
- Enhancing privacy: Competitors and algorithms can’t easily detect the full scale of your trade.
- Improving execution quality: Smoother entry or exit points lead to better average prices over time.
These benefits make iceberg orders especially valuable for institutional traders, high-net-worth individuals, or anyone managing large positions in low-liquidity pairs.

Setting Up an Iceberg Order on OKX
Whether you're using the mobile app or web platform, accessing and configuring an iceberg order is straightforward.
On Mobile
- Open the OKX app and enter exchange mode.
- Tap the bento menu (☰) in the top-left corner.
- Navigate to Trade > Bots > Slicing Bots > Iceberg.
Select your trading pair and input:
- Amount per order
- Number of visible orders
- Total order amount
- Adjust advanced settings if desired (e.g., limit price, start conditions).
- Review and confirm.
On Web
- Go to the OKX website and log in.
- Click Trade in the main navigation bar.
- Choose Trading Bots > Slicing Bots > Iceberg.
- Fill out the basic info and optional advanced settings.
- Confirm after reviewing all details.
Once active, your bot will appear under the Details tab, where you can monitor progress, view open orders, and access historical data.
Key Configuration Settings Explained
To get the most out of iceberg orders, it’s essential to understand each parameter:
Amount Per Order
Determines how much of the asset is placed in each visible segment. The actual amount may vary slightly—typically multiplied by a random factor between 0.5 and 1.0—to further obscure trading patterns.
Number of Visible Orders
Sets how many partial orders are active on the book at once. For example, setting this to five means five separate limit orders will be maintained across different price levels.
Limit Price
Acts as a safety boundary:
- For buys, orders pause if market price exceeds this level.
- For sells, placement stops if price falls below it.
Trading resumes automatically when conditions return to favorable levels.
Start Conditions
Choose when your bot activates:
- Instant: Begins immediately upon confirmation.
- Price Trigger: Waits for a specific market price.
- RSI Trigger: Launches when Relative Strength Index reaches a defined threshold (e.g., oversold/overbought).
Real-World Example
Suppose you want to buy 5 BTC when the price is below 35,000 USDT using an iceberg order:
- Set amount per order to 0.1 BTC
- Set visible orders to 5
- Choose price-speed balance preference
- Set limit price at 35,000 USDT
- Start immediately
The bot will:
- Maintain five active buy orders across mid-to-bid prices.
- Replenish filled or canceled orders dynamically.
- Halt activity if BTC/USDT rises above 35,000.
- Resume once price drops back below threshold.
This ensures stealthy accumulation without disrupting market equilibrium.
