Cboe Silexx platform enhances precision
Cboe Silexx, a multi-asset order execution management system (OEMS) that caters to the professional marketplace, goes for precision as indicated by the latest set of enhancements unveiled today.
The platform now supports four decimal places for tied orders. Furthermore, Bid / Ask Size columns reflect size across all options exchanges at the NBBO in aggregate.
Last week’s enhancements included availability of row filtering in Firm Accounts, Firm Users, and Complex Order Book. “Staged” has been added as status in Order Manager and Order History.
The platform has added new columns: “Created Date” column is available in Firm Accounts and Tag1 column is available in Trade Confirms.
Recently, Cboe Silexx has made available support for the new Cboe Options Exchange (C1) FLEX Delta Adjusted at Close (DAC) order type. The new orders are supported with effect from December 2, 2020.
The new order type will be accepted during the Regular Trading Hours (RTH) session. DAC orders are limit orders for FLEX options that execute intraday and receive a delta-adjusted price based on that day’s official closing price of the underlying security or index value.
Both simple and complex FLEX DAC orders will be supported. The maximum number of legs on a FLEX DAC order is 99. This differs from the number of legs supported on FLEX and non-FLEX orders without the DAC instruction, which is 100.
