Iceberg order
An iceberg order is a type of large trading order that is divided into smaller, more manageable chunks to conceal the true size of the order from the market. This technique is used to minimize the impact on the market price and to avoid alerting other traders to the presence of a large order. Only a small portion of the total order is visible in the order book at any given time, with the rest remaining hidden, much like the bulk of an iceberg beneath the surface of the water.
