Which statements regarding on book matching are correct?

The statement regarding partial executions being possible in continuous trading and in auctions is accurate because both trading methods allow for the execution of orders in portions rather than as whole units. This feature is essential for liquidity, as it enables traders to fill large orders gradually without impacting the market price significantly. In continuous trading, orders can be executed in parts as they interact with incoming market orders, while in auctions, partial fills can occur if there is insufficient liquidity to meet the entirety of an order at the determined price.

The nature of how trades are executed, whether continuously or in an auction format, allows for this flexibility, ensuring that traders are able to effectively manage their positions and orders in line with market conditions. Understanding this capability is crucial for traders, as it impacts trading strategies and liquidity management on exchanges like Eurex.
