Wat is Pegged order, midpoint peg?

Ook bekend als: pegged order · midpoint peg

Definition 2.5 Microstructure and Execution · Hoofdstuk 2 — Order Types and Their Uses

A pegged order has no fixed price: the venue sets it from a reference quote and resets it whenever the reference moves, within an optional limit. A primary peg follows the best quote on its own side; a midpoint peg rests hidden at the midpoint of the best bid and best ask.

Two display conditions. Top: an iceberg shows one slice; when it is consumed, the venue shows the next slice at the back of the queue. Bottom: a midpoint peg rests, invisible, halfway between the best bid and ask.
