Cboe Silexx, a multi-asset order execution management system (OEMS) that caters to the professional marketplace, has announced a series of enhancements as part of version 24.8.

• FLEX Ticket | Theoretical Pricer

Theoretical prices and greeks are now available in the FLEX ticket for fixed price type options. The theo prices are powered from Hanweck by fitting a vol surface to determine the IV and price based on user defined parameters. Prices can be applied on a leg-by-leg basis by double clicking or applied all at once by clicking ‘Apply Leg Prices’.

To enable the pricer, navigate to the FLEX ticket settings gear icon in top right corner of the ticket.

• Silexx API

Cboe announces the production release of the new gRPC, REST, and .NET API. This enables traders to place orders, monitor transactions, and get portfolio updates. The API is also available in Cboe’s certification environment for developers to build and test prior to deploying in live markets.
