Key Highlights

  • An iceberg order is a large trading order that is broken down into smaller segments, with only a limited portion shown publicly on the market at any given moment.

  • This strategy is used to conceal the full size of the order and to minimize its impact on market prices.

What is Iceberg Order?

An iceberg order is a large trading order that is broken down into smaller segments, with only a limited portion shown publicly on the market at any given moment. Only a small part of the overall order is displayed on the order book at a time, keeping the full size hidden from other traders. This strategy is used to conceal the full size of the order and to minimize its impact on market prices.

How Does It Work?

  • Order Splitting: The huge order is chopped into smaller bits, called “legs” or “sub-orders.” Only the first bit shows up in the market’s order book for everyone to see.

  • Gradual Execution: Once that visible chunk gets filled, the next hidden piece pops up automatically, and this keeps going until the whole order is done.

  • Concealment: Most of the order stays out of sight, so other traders can’t guess the full plan or size of the trade.

Purpose and Benefits

  • Minimizing Market Impact: By revealing only small parts of the order, it avoids big price swings that could happen if everyone saw the full order at once.

  • Avoid Price Slippage: Large trades can push prices away from what you wanted to pay or get. Iceberg orders keep things discreet to lock in better prices.

  • Reducing Impact Cost: Big orders can drive up trading costs by spooking the market. Smaller, hidden trades help keep these “impact costs” down.

Who Uses Them and When?

  • Institutional Investors: Large institutions such as hedge funds, pension funds, or market makers commonly use iceberg orders to execute significant trades without alerting the market to their intentions.

  • Day Traders and Market Makers: Day traders or market makers might spot iceberg orders and use them as clues about where prices could hold steady (support) or face resistance.
