Rithmic Enhancements

Significant enhancements have been added to our Rithmic connector (some of which have been described in the DOM Enhancements section: MBO, Bid/Ask Counts, Depth Levels and Position in Queue).

Native Order Types

The following native implementations have been added for the following types of orders:

  1. OCO – One Cancels Other

  2. Bracket (Attached) Orders – Limit/Stop orders with attached profile/stop orders

  3. Trailing Stop – Trailing stop orders

  4. LIT/MIT – Limit if Touched/Market if Touched

  5. Iceberg – Limit orders with the actual size hidden

@Bid/@Ask Values for Live Quotes

Live quotes use the “Aggressor Side” flag to determine a live quote was at the bid or ask price instead of relying on the Best Bid/Ask values (which are not guaranteed to be in sync). This will ensure that live quotes are correctly interpreted for Bid vs Ask volume and will match historical tick data.
