What can be considered a major characteristic of Eurex Improve?

The major characteristic of Eurex Improve lies in its objective to enhance price execution for customer orders. This feature is designed to benefit market participants by ensuring that they receive better prices for their trades. Eurex Improve operates by allowing market makers to interact with incoming orders, providing an opportunity for better pricing compared to traditional execution methods. This mechanism ultimately fosters a more competitive trading environment, which can lead to increased liquidity and improved overall market efficiency.

The other options do not align with the core purpose of Eurex Improve. For example, limiting access to order executions would contradict the goal of facilitating better price discovery. Similarly, while non-public interactions might occur in some trading systems, Eurex Improve's primary function is not about secrecy but about enhancing execution quality for all participants. Lastly, focusing solely on large volume trades would restrict the advantages available to a broader range of orders, which contradicts the inclusive intent of improving execution across various order sizes.
