Iceberg orders are large single orders that have been divided into smaller limit orders, usually through the use of an automated program, to conceal the actual order quantity. The term “iceberg” signifies that the visible lots are merely the “tip of the iceberg,” with a greater number of limit orders ready to be placed. These orders are also known as reserve orders.
Key Insights
- Iceberg orders are substantial orders split into smaller, visible and hidden portions, with parts transitioning to visibility upon execution of the visible segment.
- They are usually initiated by large institutional investors to avoid market disruption caused by a single, large order.
- Traders can capitalize on iceberg orders by buying shares just above the price levels supported by the initial batches of an iceberg order.
Essentials of Iceberg Orders
Iceberg orders are primarily utilized by institutional investors to buy and sell significant securities volumes without alerting the market. At any given moment, only a fragment of their full order is visible on Level 2 order books, helping mitigate the price fluctuations caused by substantial changes in a stock’s supply and demand.
For instance, an institutional investor might avoid placing a large sell order to circumvent market panic. Alternatively, a series of smaller limit sell orders could disguise selling pressure more effectively. Likewise, investors looking to purchase shares at the lowest possible price might refrain from placing large buy orders that day traders could spot and leverage, potentially driving up the stock price.
Previous research indicates that traders often place orders simulating the iceberg orders’ amount and pattern, thereby enhancing liquidity and minimizing the iceberg order’s market impact.
Spotting Iceberg Orders
Skilled traders can identify iceberg orders by observing a series of limit orders from a single market maker that consistently reappear. An institutional investor might split a one-million-share order into ten smaller orders of 100,000 each. Traders must remain vigilant to recognize these patterns and understand that these orders are filling in real-time.
Traders aiming to profit from these dynamics might purchase shares slightly above these levels, acknowledging that strong support from the iceberg order exists. Consequently, these orders can act as dependable support and resistance areas within a broader analysis of other technical indicators.
As an illustrative scenario, a day trader might observe elevated selling volume at a certain price. Checking the Level 2 order book, they notice this volume predominantly originates from a sequence of similarly-sized sell orders by the same market maker. Interpreting this as a potential iceberg order, the trader might decide to short sell the stock due to unceasing selling pressure from successive limit sell orders.
Markets typically prioritize orders based on their receipt sequence; hence, the visible segment of an iceberg order executes first. The hidden segment only becomes executable once it appears on the order book. If other traders have placed similar-sized orders, they will execute after the visible segment of the iceberg order.
Concrete Example of an Iceberg Order
Imagine a large pension fund aims to invest $5 million in stock ABC. Publicizing this investment could skyrocket ABC’s price within a brief window. To prevent market disruption, the fund designs an iceberg order that divides its initial order into $500,000 increments.
