Frequently Asked Questions (FAQs)

What is the working of iceberg order?

Those traders employ iceberg orders who generally trade in large quantities in the stock market. Trade in large volumes has the potential to change the market prices of the security substantially as a large quantity of sell or buy orders creates pressure on the supply and demand function of the market respectively.

For instance, a single order to purchase 100,000 shares of a stock represents a substantial rise in the demand for that stock. As a result, the price of the stock can be pushed higher by the other traders. Similarly, when a single order to sell appears in the market, then the pressure on the supply side increases and the prices of the security can decline.

Traders who are indulging in large quantity trade generally utilise iceberg orders while implementing their sell or buy orders by dividing the transaction into smaller quantities. An iceberg order is adopted with the view that the single large transaction does not create a significant shift in the prices and causes a negative effect on their trading strategy, that is, selling or buying shares at the prices not desired by them.

While executing a large quantity trade, the traders have a concern that if in case the other market participants came to know about the transactions then they might further create a supply or demand pressure and the trader will not be able to execute the trade on the price desired by them.

For instance, if Mr. X comes to know about the large quantity trade which will be executed by an institutional investor then they will be able to predict the rise in the share prices. Therefore, they will make investments in that stock. This may result in an increase in the prices as Mr. X will also start making investments in that stock only. In effect, the institutional trader must pay higher prices for investing in the security.

The division in the smaller quantities ensures that the market is not tipped. At a specific time, only the smaller portion of the quantities traded are visible on order book’s level 2. By hiding the trade of larger quantities in the stock market, a significant and substantial amount of price movement can be avoided.
