Trading fractional shares allows you to invest in companies which you may not be able to afford the full share price. It also makes it easier for you to diversify your portfolio by allowing you to purchase fractional amounts in multiple companies when you otherwise may have only been able to purchase whole shares in one or two companies.
If you enable your account to trade in fractions, we will buy or sell a fraction of a share based on the amount of cash you specify. For example, if you want to spend $500 but one share of the stock you want to buy is currently $1000 you would end up with 0.5 shares.
Who is eligible for fractional share permissions?
All individual, standalone accounts (except those who reside in Israel, Canadian RRSP/TFSA accounts and Interactive Brokers Securities Japan Inc. ("IBSJ") entity accounts) are eligible for fractional share permissions.
Financial Advisors, Money Managers, and Introducing Brokers may enable their clients on an all-or-none basis.
How do I enable fractional shares?
If you are eligible then you can enable fractional share trading in Client Portal. Click the User menu (head and shoulders icon in the top right corner) followed by Settings. Under Account Settings find the section Trading and click on Trading Permissions. Scroll to "Stocks", click +Add and check the box next to "Global (Trade in Fractions)" and click on SAVE. Then click CONTINUE and follow the prompts on screen. You will then be able to trade in fractions in eligible stocks for which you have permission to trade. To trade fractions of eligible U.S. stocks, you will need to sign up to trade U.S. stocks, and to trade fractions of eligible European stocks, you will need to sign up to trade European stocks.
Please note, TWS Build Version 979 or later is required to trade fractional shares. This feature currently supports most order types.
What products can I trade in fractions?
We offer fractional share trading on eligible U.S., Canadian and European stocks and ETFs*.
A list of eligible stocks that can be traded in fractional shares is available via the following link. Please note, this list is subject to change without notice:
http://www.ibkr.com/download/fracshare_stk.csv
*Under EU regulations, EU retail clients generally cannot trade U.S. ETFs, in whole or fractional increments.
Can I short fractional shares?
IBKR does support short sales in fractional shares of eligible stocks as long as you have margin and approved trading permissions to trade fractional shares of stocks listed in the U.S. or in Europe.
What are the fees associated with fractional shares?
There is no additional fee to use fractional share trading. Standard commission rates (both IBKR Lite and IBKR Pro, where applicable) apply.
What order types can I choose for fractional trading?
IBKR will only accept certain types of orders for fractional shares (e.g., market orders, limit orders, stop orders, stop limit orders, etc.). If you choose to place an unmarketable limit order with a fractional share component, the fractional component may not execute until the order becomes marketable (and therefore may not execute at all), even if the order might have executed earlier if submitted for a whole share quantity.
How does IBKR handle fractional shares orders in European stocks?
Depending on the size and nature of the order, IBKR will direct orders in European stocks that include a fractional share component to a pool of execution venues which might be different than those utilized for other order types. You should review the applicable order execution policy for more details.
Can I transfer fractional shares to IBKR?
IBKR does not accept fractional shares through a position transfer.
Are fractional shares eligible for the Dividend Reinvestment Program (DRIP)?
Yes, it is possible to receive fractional shares for a reinvested dividend through the Dividend Reinvestment Program (DRIP) if the account has fractional share permissions.
Please note the above does not apply in the event of mutual fund dividends, which can be re-invested and may result in holding fractional shares of the fund.
Will I receive a fractional share position from a corporate action?
If your account has been approved for trading fractions and a US or European corporate action issues fractional shares, the fractional shares will remain in your account. However, if your account does not have permissions to trade in fractions or the corporate action is issuing non-eligible shares, the fractional shares will be liquidated.
Will I have voting rights for fractional shares in my account?
You will not have voting rights for any of the fractional shares held in your account, you will not be able to make voluntary elections on any corporate action (including, without limitation, any tender offers or rights offerings) with respect to such fractional shares, and we cannot provide you any other shareholder documentation for any holdings of less than one share.
Do I receive dividends on my fractional shares?
Your fractional shares positions are eligible to receive dividends in the same manner as your full positions on the same stocks.
Is fractional trading available for the API?
Fractional trading is supported via FIX/CTCI but not via API at this time.
BACKGROUND
In 2018, an EU regulation, intended to protect “Retail” clients by ensuring that they are provided with adequate disclosure when purchasing certain products took effect. This disclosure document is referred to as a Key Information Document, or KID, and it contains information such as product description, cost, risk-reward profile and possible performance scenarios.
This regulation is known as the Packaged Retail and Insurance-based Investment Product Regulation (MiFID II, Directive 2014/65/EU), or PRIIPs, and it covers any investment where the amount payable to the client fluctuates because of exposure to reference values or to the performance of one or more assets not directly purchased by such retail investor. Common examples of such products include options, futures, CFDs, ETFs, ETNs and other structured products.
The UK Financial Conduct Authority (FCA) has equivalent requirements for UK residents.
It’s important to note that a broker cannot allow a Retail client to purchase a product covered by PRIIPs unless the issuer of that product has prepared the required disclosure document for the broker to provide to the client. U.S. clients are not impacted by PRIIPs, so the issuers of U.S. listed ETFs do not as a rule create KIDs. This means that EEA and UK Retail clients may not purchase the product. Clients nevertheless have several options:
CLIENT CATEGORISATION
We categorize all individual clients as “Retail” by default as this affords clients the broadest level of protection afforded by MiFID. Client who are categorised as “Professional” do not receive the same level of protection as “Retail” but are not subject to the KIDs requirement. As defined under MiFID II rules, “Professional” clients include regulated entities, large clients and individuals who have asked to be re-categorised as “elective professional clients” and meet the MiFID II requirements based on their knowledge, experience and financial capability.
We provide an online step-by-step process that allows “Retail” to request that their categorisation be changed to “Professional". The qualifications for re-categorisation along with the steps for requesting that one’s categorisation be considered are outlined in KB3298 or, to directly apply for a change in categorisation, the questionnaire is available in the Client Portal/Account Management.
Boerse Stuttgart and Clearstream Banking have announced that they will no longer provide services for issues whose main business is connected directly or indirectly to cannabis and other narcotics products. Consequently, those securities will no longer trade on the Stuttgart (SWB) or Frankfurt (FWB) stock exchanges. Effective as of the 19 September 2018 close, IBKR will take the following actions:
Outlined in the table below are impacted issues as announced by the Boerse Stuttgart and Clearstream Banking as of 7 August 2018. This table includes a notation as to whether the impacted issue is eligible for transfer to a U.S. listing. Note that the clearinghouses have indicated that this list may not yet be complete and clients are advised to review their respective websites for the most current information.

IMPORTANT NOTES:
Utilization Metrics
Utilization is defined as loaned shares divided by available shares in the securities lending market, expressed as a percentage. The Utilization metric on TWS is not specific to IB. It is based on industrywide data provided by a securities finance data vendor. The metric is not conclusive however, as not every lender reports their Utilization to the vendor. In addition, although the source is believed to be reliable, IBKR does not warrant its accuracy.
Generally, Utilization is the ratio of demand to supply. For example, Apple Inc. (AAPL) may have utilization of less than 1% because the stock has vast availability relative to the demand to borrow shares for shorting. Roku Inc. (ROKU) may have utilization above 90% because of higher demand to short shares as compared to the number of available shares.
For accounts enrolled in the Stock Yield Enhancement Program, a high stock-specific Utilization percentage may increase the likelihood that IB may be able to lend your shares. Conversely, stocks with a low Utilization percentage are generally in lesser demand in the securities finance market, generally reducing IB’s ability to lend your shares.
Utilization can be added as a column in TWS.
Using Mosaic Market Scanner to Determine an Indication of Stock Utilization
TWS users can find stock utilization indications by using Mosaic Market Scanner filters. After opening the scanner, Select Custom Scanner and input parameters. Some useful filters include Price, Market Cap, Fee Rate and Utilization.

Introduction
To comply with regulations regarding the sale of unregistered securities and to minimize the manual processing associated with trading shares that are not publicly quoted, IBKR imposes certain restrictions on U.S. Microcap Stocks. A list of those restrictions, along with other FAQs relating to this topic are provided below.
Microcap Restrictions
Microcap FAQs
What is a U.S. Microcap Stock?
The term “Microcap Stock” refers to shares (1) traded over the counter or (2) that are listed on Nasdaq and NYSE American that have a market capitalization of between $50 million to $300 million and are trading at or below $5. For purposes of this policy, the term Microcap Stock will include the shares of U.S. public companies which have a market capitalization at or below $50 million, which are sometimes referred to as nanocap stocks or trade on a market generally associated with Microcap Stocks.
To avoid situations where minor, short-term fluctuations in a stock price cause repeated reclassification, any stock classified as U.S. Microcap will remain in that classification until both its market capitalization and share price exceed $300 million and $5, respectively, for a 30 consecutive calendar day period.
As Microcap Stocks are often low-priced, they are commonly referred to as penny stocks. IBKR may make exceptions, including for stocks traded at low prices that recently had a greater market cap. In addition, IBKR will not consider ADRs on non-US companies to be Micro-Cap stocks.
Where do Microcap Stocks trade?
Microcap Stocks typically trade in the OTC market, rather than on a national securities exchange. They are often electronically quoted by market makers on OTC systems such as the OTC Bulletin Board (OTCBB) and the markets administered by the OTC Markets Group (e.g., OTCQX, OTCQB & Pink). Also included in this category are stocks which may not be publicly quoted and which are designated as Caveat Emptor, Other OTC or Grey Market.
In addition, U.S. regulators also consider stocks listed on Nasdaq or NYSE American trading at or below $5 with a market capitalization at or less than $300 million to be Microcap Stocks.
What happens if IBKR receives a transfer from an Eligible Client where one or more of the positions transferred is a Microcap Stock?
If IBKR receives a transfer containing a block of a Microcap stock, IBKR reserves the right to restrict the sale of any Microcap position(s) included in the transfer unless the Eligible Client provides appropriate documentation establishing that the shares were either purchased on the open market (i.e., on a public exchange through another broker) or were registered with the SEC pursuant to an S-1 or similar registration statement.
Eligible Clients can prove that shares were purchased on the open market by providing a brokerage statement or trade confirm from a reputable broker reflecting the purchase of the shares on a public exchange. Eligible Clients can establish that the shares are registered by providing the SEC (Edgar system) File number under which their shares were registered by the company (and any documents necessary to confirm the shares are the ones listed in the registration statement).
NOTE: All customers are free to transfer out any shares we have restricted at any time.
What restrictions will IBKR apply to Prime accounts?
Clients whose activities include Prime services are considered Eligible Clients solely for the purposes of those trades which IBKR has agreed to accept from its executing brokers. However, while Prime accounts may clear U.S. Microcap Stocks at IBKR, those shares will be restricted until such time IBKR confirms that the shares are eligible for re-sale under the procedures discussed above.
To remove the restriction for shares purchased on the open market, please have the executing broker provide a signed letter on company letterhead or an official Account Statement stating that the shares were purchased in the open market. The letter or statement must also include the below required criteria. Alternatively, if the shares were acquired through an offering the letter or statement must provide documents or links to the relevant registration statement and state that the shares were part of it.
Required Broker Letter Criteria:
1) IBKR Account Number
2) IBKR Account Title
3) Trade Date
4) Settlement Date
5) Symbol
6) Side
7) Price
8) Quantity
9) Time of Execution
10) Exchange
11) Must be signed
12) Must be on Firm's official letterhead
To summarize: Sell Long trades will be accepted if the long position is no longer restricted. Sell Short trades will be accepted. Buy Long trades will be accepted and the position will be restricted until Compliance is provided with sufficient information to remove the restriction. Buy Cover trades and intraday round trip trades will not be accepted.
What happens if a stock you purchase gets reclassified as Grey Market or Caveat Emptor?
If you purchase a stock in your IBKR account that at a later date becomes classified as a Caveat Emptor or Grey Market stock, you will be allowed to maintain, close or transfer the position but will not be able to increase your position.
What are some of the reasons why Microcap Stock trading may be restricted in my account?
There are two primary reasons why you might be restricted from trading in a Microcap Stock:
If one of the above reasons apply, trading will be restricted in the security and a notification will be sent to the customer’s message center in Account Management. This notification will describe the reason for the restriction and the steps the customer must take before IBKR will consider lifting the restriction.
Why does IBKR consider me to be a potential affiliate of a Microcap Stock issuer?
An “affiliate” is a person, such as an executive officer, a director or large shareholder, in a relationship of control with the issuer.
Rule 144 applies to all securities, including Microcap Stocks. However, given the heightened risks associated with trading Microcap Stocks, if a customer’s trading and/or holdings in a Microcap Stock are close to the Rule 144 Thresholds, IBKR will restrict the customer’s trading in the Microcap Stock. This restriction will remain in effect pending a compliance review into the customer’s potential affiliate status.
For the Potential Affiliate review, why do I need to ask for a new review every two weeks?
A customer’s affiliate status may change soon after IBKR completes the above-referenced Potential Affiliate review. As such, IBKR believes it is appropriate to refresh a Potential Affiliate review every two weeks if a customer’s trading activity and/or holdings in the Microcap Stock remain close to the Rule 144 Thresholds.
Where can I find a list of stocks that IBKR has designated as U.S. Microcaps?
A list of stocks designated as U.S. Microcaps by IBKR is available via the following link: www.ibkr.com/download/us_microcaps.csv
Note that this list is updated daily.
Where can I find additional information on Microcap Stocks?
Additional information on Microcap Stocks, including risks associated with such stocks may be found on the SEC website: https://www.sec.gov/reportspubs/investor-publications/investorpubsmicrocapstockhtm.html

1This includes transfers by any method (e.g., ACATS, DWAC, FOP), conversion of Canadian listings to their U.S. equivalent via “Southbound” transfer, transfers to cover existing short positions, IB Prime customers executing with other brokers and clearing to IBKR, etc.
IEX offers a Discretionary Peg™ (D-Peg™) order type which is a non-displayed order that is priced at either the National Best Bid (NBB for buys) or National Best Offer (NBO for sells). D-Peg™ orders passively rest on the book while seeking to access liquidity at a more aggressive price up to Midpoint of the NBBO, except when IEX determines that the quote is transitioning to less aggressive price
How to Place a D-Peg Order
Please note, the IEX D-Peg order type is only available via the TWS version 961 and above. Instructions for entering this order type are outlined below:
Step 1
Enter a symbol and choose a directed quote, selecting IEX as the destination. Right click on the data line and select Trade followed by Order Ticket to open the Order Ticket window.
Step 2

Background
Effective October 3, 2016, securities exchanges registered with the SEC will operate a Tick Size Pilot Program ("Pilot") intended to determine what impact, if any, widening of the minimum price change (i.e., tick size) will have on the trading, liquidity, and market quality of small cap stocks. The Pilot will last for 2 years and it will include approximately 1,200 securities having a market capitalization of $3 billion or less, average daily trading volume of 1 million shares or less, and a volume weighted average price of at least $2.00.
For purposes of the Pilot, these securities will be organized into groups that will determine a minimum tick size for both quote display and trading purposes. For example, Test Group 1 will consist of securities to be quoted in $0.05 increments and traded in $0.01 increments and Test Group 2 will include securities both quoted and traded in $0.05 increments. Test Group 3 will include also include securities both quoted and traded in $0.05 increments, but subject to Trade-at rules (more fully explained in the Rule). In addition, there will be a Control Group of securities that will continue to be quoted and traded in increments of $0.01. Details as to the Pilot and securities groupings are available on the FINRA website.
Impact to IB Account Holders
In order to comply with the SEC Rules associated with this Pilot, IB will change the way that it accepts orders in stocks included in the Pilot. Specifically, starting October 3, 2016 and in accordance with the phase-in schedule, IB will reject the following orders associated with Pilot Securities assigned to Test Groups:
Clients submitting orders via the trading platform that are subject to rejection will receive the following pop-up message:
The following order types will continue to be accepted for Pilot Program Securities:
- Test Group 2 and 3 in .005
Other Items of Note
Please note that the contents of this article are subject to revision as further regulatory guidance or changes to the Pilot Program are issued.
How are executions allocated when an order receives a partial fill because an insufficient quantity is available to complete the allocation of shares/contracts to sub-accounts?
Overview:
From time-to-time, one may experience an allocation order which is partially executed and is canceled prior to being completed (i.e. market closes, contract expires, halts due to news, prices move in an unfavorable direction, etc.). In such cases, IB determines which customers (who were originally included in the order group and/or profile) will receive the executed shares/contracts. The methodology used by IB to impartially determine who receives the shares/contacts in the event of a partial fill is described in this article.
Background:
Before placing an order CTAs and FAs are given the ability to predetermine the method by which an execution is to be allocated amongst client accounts. They can do so by first creating a group (i.e. ratio/percentage) or profile (i.e. specific amount) wherein a distinct number of shares/contracts are specified per client account (i.e. pre-trade allocation). These amounts can be prearranged based on certain account values including the clients’ Net Liquidation Total, Available Equity, etc., or indicated prior to the order execution using Ratios, Percentages, etc. Each group and/or profile is generally created with the assumption that the order will be executed in full. However, as we will see, this is not always the case. Therefore, we are providing examples that describe and demonstrate the process used to allocate partial executions with pre-defined groups and/or profiles and how the allocations are determined.
Here is the list of allocation methods with brief descriptions about how they work.
· AvailableEquity
Use sub account’ available equality value as ratio.
· NetLiq
Use subaccount’ net liquidation value as ratio
· EqualQuantity
Same ratio for each account
· PctChange1:Portion of the allocation logic is in Trader Workstation (the initial calculation of the desired quantities per account).
· Profile
The ratio is prescribed by the user
· Inline Profile
The ratio is prescribed by the user.
· Model1:
Roughly speaking, we use each account NLV in the model as the desired ratio. It is possible to dynamically add (invest) or remove (divest) accounts to/from a model, which can change allocation of the existing orders.
Basic Examples:
Details:
CTA/FA has 3-clients with a predefined profile titled “XYZ commodities” for orders of 50 contracts which (upon execution) are allocated as follows:
Account (A) = 25 contracts
Account (B) = 15 contracts
Account (C) = 10 contracts
Example #1:
CTA/FA creates a DAY order to buy 50 Sept 2016 XYZ future contracts and specifies “XYZ commodities” as the predefined allocation profile. Upon transmission at 10 am (ET) the order begins to execute2but in very small portions and over a very long period of time. At 2 pm (ET) the order is canceled prior to being executed in full. As a result, only a portion of the order is filled (i.e., 7 of the 50 contracts are filled or 14%). For each account the system initially allocates by rounding fractional amounts down to whole numbers:
Account (A) = 14% of 25 = 3.5 rounded down to 3
Account (B) = 14% of 15 = 2.1 rounded down to 2
Account (C) = 14% of 10 = 1.4 rounded down to 1
To Summarize:
A: initially receives 3 contracts, which is 3/25 of desired (fill ratio = 0.12)
B: initially receives 2 contracts, which is 2/15 of desired (fill ratio = 0.134)
C: initially receives 1 contract, which is 1/10 of desired (fill ratio = 0.10)
The system then allocates the next (and final) contract to an account with the smallest ratio (i.e. Account C which currently has a ratio of 0.10).
A: final allocation of 3 contracts, which is 3/25 of desired (fill ratio = 0.12)
B: final allocation of 2 contracts, which is 2/15 of desired (fill ratio = 0.134)
C: final allocation of 2 contract, which is 2/10 of desired (fill ratio = 0.20)
The execution(s) received have now been allocated in full.
Example #2:
CTA/FA creates a DAY order to buy 50 Sept 2016 XYZ future contracts and specifies “XYZ commodities” as the predefined allocation profile. Upon transmission at 11 am (ET) the order begins to be filled3 but in very small portions and over a very long period of time. At 1 pm (ET) the order is canceled prior being executed in full. As a result, only a portion of the order is executed (i.e., 5 of the 50 contracts are filled or 10%).For each account, the system initially allocates by rounding fractional amounts down to whole numbers:
Account (A) = 10% of 25 = 2.5 rounded down to 2
Account (B) = 10% of 15 = 1.5 rounded down to 1
Account (C) = 10% of 10 = 1 (no rounding necessary)
To Summarize:
A: initially receives 2 contracts, which is 2/25 of desired (fill ratio = 0.08)
B: initially receives 1 contract, which is 1/15 of desired (fill ratio = 0.067)
C: initially receives 1 contract, which is 1/10 of desired (fill ratio = 0.10)
The system then allocates the next (and final) contract to an account with the smallest ratio (i.e. to Account B which currently has a ratio of 0.067).
A: final allocation of 2 contracts, which is 2/25 of desired (fill ratio = 0.08)
B: final allocation of 2 contracts, which is 2/15 of desired (fill ratio = 0.134)
C: final allocation of 1 contract, which is 1/10 of desired (fill ratio = 0.10)
The execution(s) received have now been allocated in full.
Example #3:
CTA/FA creates a DAY order to buy 50 Sept 2016 XYZ future contracts and specifies “XYZ commodities” as the predefined allocation profile. Upon transmission at 11 am (ET) the order begins to be executed2 but in very small portions and over a very long period of time. At 12 pm (ET) the order is canceled prior to being executed in full. As a result, only a portion of the order is filled (i.e., 3 of the 50 contracts are filled or 6%). Normally the system initially allocates by rounding fractional amounts down to whole numbers, however for a fill size of less than 4 shares/contracts, IB first allocates based on the following random allocation methodology.
In this case, since the fill size is 3, we skip the rounding fractional amounts down.
For the first share/contract, all A, B and C have the same initial fill ratio and fill quantity, so we randomly pick an account and allocate this share/contract. The system randomly chose account A for allocation of the first share/contract.
To Summarize3:
A: initially receives 1 contract, which is 1/25 of desired (fill ratio = 0.04)
B: initially receives 0 contracts, which is 0/15 of desired (fill ratio = 0.00)
C: initially receives 0 contracts, which is 0/10 of desired (fill ratio = 0.00)
Next, the system will perform a random allocation amongst the remaining accounts (in this case accounts B & C, each with an equal probability) to determine who will receive the next share/contract.
The system randomly chose account B for allocation of the second share/contract.
A: 1 contract, which is 1/25 of desired (fill ratio = 0.04)
B: 1 contract, which is 1/15 of desired (fill ratio = 0.067)
C: 0 contracts, which is 0/10 of desired (fill ratio = 0.00)
The system then allocates the final [3] share/contract to an account(s) with the smallest ratio (i.e. Account C which currently has a ratio of 0.00).
A: final allocation of 1 contract, which is 1/25 of desired (fill ratio = 0.04)
B: final allocation of 1 contract, which is 1/15 of desired (fill ratio = 0.067)
C: final allocation of 1 contract, which is 1/10 of desired (fill ratio = 0.10)
The execution(s) received have now been allocated in full.
Available allocation Flags
Besides the allocation methods above, user can choose the following flags, which also influence the allocation:
· Strict per-account allocation.
For the initially submitted order if one or more subaccounts are rejected by the credit checking, we reject the whole order.
· “Close positions first”1.This is the default handling mode for all orders which close a position (whether or not they are also opening position on the other side or not). The calculation are slightly different and ensure that we do not start opening position for one account if another account still has a position to close, except in few more complex cases.
Other factor affects allocations:
1) Mutual Fund: the allocation has two steps. The first execution report is received before market open. We allocate based onMonetaryValue for buy order and MonetaryValueShares for sell order. Later, when second execution report which has the NetAssetValue comes, we do the final allocation based on first allocation report.
2) Allocate in Lot Size: if a user chooses (thru account config) to prefer whole-lot allocations for stocks, the calculations are more complex and will be described in the next version of this document.
3) Combo allocation1: we allocate combo trades as a unit, resulting in slightly different calculations.
4) Long/short split1: applied to orders for stocks, warrants or structured products. When allocating long sell orders, we only allocate to accounts which have long position: resulting in calculations being more complex.
5) For non-guaranteed smart combo: we do allocation by each leg instead of combo.
6) In case of trade bust or correction1: the allocations are adjusted using more complex logic.
7) Account exclusion1: Some subaccounts could be excluded from allocation for the following reasons, no trading permission, employee restriction, broker restriction, RejectIfOpening, prop account restrictions, dynamic size violation, MoneyMarketRules restriction for mutual fund. We do not allocate to excluded accountsand we cancel the order after other accounts are filled. In case of partial restriction (e.g. account is permitted to close but not to open, or account has enough excess liquidity only for a portion of the desired position).
Footnotes:
Tick Size Pilot ("TSP" or "Pilot") Program:
Under the TSP Program, if IBKR 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), IBKR will REJECT that order, subject to limited exceptions. IBKR 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.

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 that 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 that 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 is added to Test Group due to a corporate action, IBKR will cancel the GTC order if it is priced in impermissible increments.
