Which statement does not apply to Eurex EnLight transactions?

Eurex EnLight is a platform designed to enhance the trading experience by allowing participants to solicit quotes from responders. The statement that Eurex EnLight transactions cannot be canceled is not applicable because, in practice, requests for quotes can indeed be canceled by the requester before a response is accepted.

The other statements reflect the platform's functionalities accurately. For example, requesters have the capability to call for both firm and indicative quotes, allowing them to assess the market more effectively. Additionally, trades executed within the Eurex EnLight framework are categorized as on-book trades, indicating that they are recorded on the exchange's central order book, which ensures transparency and market integrity. Furthermore, requesters have the flexibility to accept multiple quotes from different responders, facilitating better decision-making and potentially more favorable trading outcomes. Thus, the option regarding the impossibility of canceling transactions does not align with the features of Eurex EnLight.
