ICEBERG ORDERS
In recent years, electronic trading
platforms have added the capability to
place iceberg orders. What are they, and
are they helpful to the average retail
trader?
The reference to iceberg stems from
the idea that the tip of the iceberg is the
only visible part of a large mass of ice
emerging from a body of water. Accordingly,
the term iceberg order is defined
as the practice of breaking up an order to
buy or sell a large quantity of contracts
into multiple smaller orders through the
use of automated software. As the futures
markets moved from open-outcry execution
to electronic, this order type has
become more popular. This is because
traders — retail or commercial — who
trade large quantities typically prefer to
mask the true volume from view of others.
In other words, iceberg orders enable
the public to see only a small portion of
the actual order at a time.
Most futures trading platforms offer
the ability to view DOM (depth of
market) data in which it is possible to
observe the working buy limit and sell
limit orders of other traders. These working
orders on display are often referred to
as the “book.” Some traders monitor the
trading book for large-quantity orders.
In theory, large buy orders indicate the
market may be inclined to move higher,
or at least it suggests that large players
believe it will. These inferences, whether
right or wrong, can influence prices and
possibly prevent the entity placing the
large quantity to be filled at their desired
price. As a result, funds and institutions
placing sizable orders have incentive
to mask the true quantity of their order.
Simply put, those using iceberg orders do so under the belief that it will reduce the
impact the order has on price movement
as it is absorbed into the market.
When an iceberg order is placed, the
trader determines the disclosed volume,
which will be placed as a regular limit
order, and the hidden volume, which is
placed once the first trade is filled. For
most retail traders, iceberg orders are
not necessary, but the ability to execute
them is available on most futures trading
platforms, which is why it’s a good idea to understand what they are. However,
it’s typically not a good idea for average
retail traders to use this order type. Those
trading small quantities will have little or
no impact on prices, so there is no need
to disguise the quantity. Furthermore,
because the hidden quantity is placed
after the disclosed quantity, it will fall
to the bottom of the priority list in the
exchanges’ trade-matching system. In
other words, traders unnecessarily using
iceberg orders are reducing their odds of
getting filled at their limit price.
