SEC Tick Size Pilot Program FAQs

Tick Size Pilot ("TSP" or "Pilot") Program:

Under the TSP Program,  if IB receives any order in a Pilot Security that does not conform to the designated pricing increment (e.g., a limit price in a $0.01 increment for a security designated as trading $0.05 increments), IB will REJECT that order, subject to limited exceptions. IB strongly encourages a thorough review of your software or your vendor’s software to understand the criteria for what causes an order in a Pilot Security to be rejected to permit you or your vendor to make changes to correctly handle orders in Test Group Pilot Securities.
 

FREQUENTLY ASKED QUESTIONS:

Q: What is the Tick Size Pilot?
A: On May 6, 2015 the SEC approved an amended TSP NMS Plan. The Pilot will be two years in length. Data collection for the Pilot began on April 4, 2016, 6 months prior to the implementation of the trading and quoting rules for the Pilot. Implementation of the trading and quoting rules for the Pilot will begin on October 3, 2016.

The Pilot will be conducted using a Control Group and three Test Groups where variations in quoting and trading rules exist between each group. Please see the TSP NMS Plan for additional information.

 

Q: Will the Pilot quoting and trading rules apply during regular market hours, pre-market hours and post market hours?
A: The Pilot rules apply during all operational hours (pre-market, regular hours, and post market hours trading).

 

Q: Will the Pilot quoting and trading rules apply to odd-lot and mixed-lot sizes?
A: Yes, the Pilot rules to all order sizes.

 

Q: Will orders in Control Group Securities be accepted in price increments of less than $0.05?
A: Yes, orders submitted in price increments of less than $0.05 will continue to be accepted in Control Group securities.

 

Q: Will orders in a Test Group 1, 2 or 3 Pilot Securities be accepted in price increments of less than $0.05?
A: No, unless covered by an exception, orders submitted in price increments of less than $0.05 will be rejected.

 

Q: Which Pilot Security Orders in Test Groups will Interactive Brokers accept at other than $0.05 increments?
        Midpoint orders with no explicitly stated limit price or impermissible offsets will be accepted
        VWAP orders which do not have an explicitly stated limit price or impermissible offsets will be accepted.
        Interactive Brokers will accept Exchange operated Retail Price Improvement orders as follows:
                  Test Group 1 in $0.001 price increments
                  Test Groups 2 and 3 in $0.005 price increments.

 

Q: Will there be any changes to the Opening / Closing processes on Exchanges?
A: Please refer to each of the exchange rules for details but in general there will be no changes to the Opening / Closing process. All orders entered and eligible to participate in Exchange Opening / Closing Cross will be accepted in increments of $0.05. The Exchanges will begin publishing all quotes in increments of $0.05; however, Net Order Imbalance Indicator prices may be published in increments of $0.025.

 

Q: What will happen to my GTC order that was placed prior to October 3rd in a Pilot Stock that was priced in impermissible tick increments?
A: Interactive Brokers will adjust outstanding limit and stop GTC orders in Pilot stocks in Test Groups that are not in permissible tick increments (e.g., a buy limit order at $5.01 will be adjusted to $5.00 and a sell limit at $5.01 adjusted to $5.05).

 

Q: What will happen to my GTC order placed after October 3rd that was placed and accepted in a nickel tick increment but the Pilot Stock moves from a Test Group to the Control Group which permits non-nickel increments?
A: The GTC order will automatically be able to be revised by the user in non-nickel increments on the date the Pilot stock moves from the Test Group to the Control Group. Similarly, if a stock gets added to Test Group due to a corporate action, IB will cancel the GTC order if it is priced in impermissible increments.
