Q17: DOES LEVEL ATS UTILIZE INDICATIONS OF INTEREST (IOI) IN ANY WAY? A17: LeveL ATS accepts both Firm Orders and Conditional Orders. Conditional Orders, which function similarly to IOIs, never execute and, instead, are instructions to the LeveL ATS that the subscriber wishes to interact with the LeveL ATS order book on a conditional basis. In the event eligible contra party interest exists, the subscriber that submitted the Conditional Order will be sent an invitation to submit a Firm-Up Response Order to the LeveL ATS.

LeveL's default system setting for Firm Orders is to not generate invitation requests, (IOIs). Subscribers have the option to request that this default setting be removed for their orders. Once removed, subscribers may designate, on an order-by-order basis, which of their Firm Orders are ineligible to generate a Firm-Up Invitation (IOI) to Conditional Orders.
Q18: HOW DOES LEVEL ATS HANDLE CONDITIONAL ORDERS? A18: A Conditional Order is an instruction to the ATS that the participant wants to interact with the order book on a conditional basis. A Conditional Order never executes; instead, when a Conditional Order would have otherwise matched with a contra party, the Conditional Order will be canceled by LeveL ATS and an invitation will be sent to the originating participant, inviting them to send a Firm-Up Response Order.

  • LeveL ATS will honor all execution instructions on an order-by-order basis for Conditional Orders and Firm-Up Response Orders; however, executions will only occur at the midpoint of the NBBO at the time of the execution.
  • All Participants in good standing are allowed to place Conditional Orders.
  • All Fills on Conditional Order Firm-Up Responses will only be non-aggregated fills.
Q19: HOW DOES CANCEL-REPLACE AFFECT MY ORDERS PRIORITY? A19: A reduction in quantity is the only change that will maintain an orders current priority in the LeveL ATS book. All other changes will result in the order being treated as a new order. Q20: DOES LEVEL ATS SUPPORT ODD LOTS OR MIXED LOTS? A20: LeveL ATS does not support Odd Lots. Odd Lots will be rejected. Mixed Lots will be accepted; however, only the Round Lot portion will be available for execution. The remaining Odd Lot will be canceled back to the user following the last Round Lot execution.Q21: DOES LEVEL ATS SUPPORT MIN QTY? A21: Yes. By default LeveL ATS allows aggregation to satisfy MinQty, however; subscribers, can include an execution instruction on an order-by-order basis to achieve only non-aggregated fills. Subscribers can also choose from several other execution instructions to further control how their leaves are handled in relation to their MinQty instructions. Please contact LeveL ATS at Helpdesk@LeveLATS.com or 800-958-4813 for more details.Q22: HOW ARE ORDERS HANDLED IN A LOCKED MARKET? A22: LeveL ATS will execute in a locked market by default; however, users can include an execution instruction on an order-by-order basis to prevent order matching in a locked market. Please contact LeveL ATS for more details Helpdesk@LeveLATS.com or 800-958-4813.Q23: HOW DOES LEVEL ATS DETERMINE PRICE IMPROVEMENT A23: LeveL ATS is designed to split price improvement equally between both sides of an execution of Firm Orders.

Firm-Up Response Orders will only execute at the Midpoint of the NBBO at the time of the execution.

Where two Firm orders are eligible to match at multiple price levels, LeveL ATS will seek to match the orders at or within the NBBO at the midpoint of the trading range as determined by each order's instructions.


Example:
Where the NBBO is $10.00 X $10.01, a midpoint pegged buy order is sent ($10.0050). The seller enters a market sell order at $10.00. LeveL ATS will match the orders at $10.0025, splitting the price improvement equally between both orders.
Q24: DOES LEVEL ATS OFFER THE ABILITY TO CUSTOMIZE THE TYPE OF FLOW I INTERACT WITH? A24: Yes. LeveL ATS offers all users the ability to customize their eligible contra party interaction. For more information please contact our Sales Desk at Salesdesk@levelats.com or 617-203-3156.
Q25: DOES LEVEL ATS PROVIDE CUSTOMIZED REPORTS? A25: Upon request, LeveL will review any such request and, when appropriate, provide customized reports. For more information please contact our Help Desk at Helpdesk@levelats.com or 800-958-4813.
