Your question - "What is an iceberg order?":

An iceberg order is when you put in a huge Bid order pretending to buy, or a huge Ask order pretending to sell, which has a big influence on moving the Bids and Asks in the market.

While i agree the process you go on to describe as icebergs is an method used by brokerage houses it is not to the best of my knowledge iceberg trading.

Below are two definitions fro iceberg orders

Canada Stockwatch (CS) offers the following definition.........

Iceberg Orders: An iceberg order is an order where the displayed volume is lower than the actual volume. This helps those wishing to trade large amounts of stock keep their intentions secret. While it is not possible to know for sure that an order is an iceberg order, we are identifying orders which may be iceberg orders. These are orders which have had trades applied to them, but the resulting volume after the trade was not as low as it should have been. In this case you will see the order volume displayed normally, with a red number underneath. This is the number of shares that have already traded on this order. It is impossible to know what the total desired volume is for an iceberg order.

As a side note CS identifies possible iceberg orders but "level II" as posted on here does not.

Investopedia.com offers the following definition...

Cedartree if I misread your definition I apologise, but IMO the size of the order or the placement of the order does not determine or constitute an iceberg order.

Iceberg orders appears on KXL sometimes but for example if might show an ask of 4,000 but if you look at true level II you might see that already 10,000 has been sold while the amount showing remains the same.

My apologies in advance for the formatting of the Investopedia.com definition.

cheers
