nyitóaukcióban

A nyitóaukcióban, in English "opening auction," refers to the initial trading period on a stock exchange where the opening price of a security is determined. This price is established based on the buy and sell orders that have accumulated during the pre-opening phase. The goal of the opening auction is to set a fair and efficient price for a security at the start of the trading day, allowing trading to commence smoothly.

During the pre-opening period, investors can submit orders to buy or sell securities. These orders are collected and matched by the exchange's trading system. If there is an imbalance between the number of buy and sell orders, or if the prices are too far apart, a single price is calculated that best satisfies the most orders. This calculated price becomes the opening price. Once the opening price is determined, the exchange transitions into the continuous trading session, where buy and sell orders are matched in real-time.

The opening auction is a crucial part of the trading day, as it provides liquidity and price discovery for securities. It helps to avoid excessive price volatility at the beginning of trading and ensures that all market participants have access to the same opening price. Different exchanges may have slightly varying rules and procedures for their opening auctions, but the fundamental principle of price determination through order matching remains consistent.
