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.


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.


Q: Where can I find out more information?

A: See KB2752 or the FINRA website for additional details regarding the Pilot Program:

Additional Information Regarding the Use of Stop Orders

U.S. equity markets occasionally experience periods of extraordinary volatility and price dislocation. Sometimes these occurrences are prolonged and at other times they are of very short duration. Stop orders may play a role in contributing to downward price pressure and market volatility and may result in executions at prices very far from the trigger price. 

Investors may use stop sell orders to help protect a profit position in the event the price of a stock declines or to limit a loss. In addition, investors with a short position may use stop buy orders to help limit losses in the event of price increases. However, because stop orders, once triggered, become market orders, investors immediately face the same risks inherent with market orders – particularly during volatile market conditions when orders may be executed at prices materially above or below expected prices.
While stop orders may be a useful tool for investors to help monitor the price of their positions, stop orders are not without potential risks.  If you choose to trade using stop orders, please keep the following information in mind:
·         Stop prices are not guaranteed execution prices. A “stop order” becomes a “market order” when the “stop price” is reached and the resulting order is required to be executed fully and promptly at the current market price. Therefore, the price at which a stop order ultimately is executed may be very different from the investor’s “stop price.” Accordingly, while a customer may receive a prompt execution of a stop order that becomes a market order, during volatile market conditions, the execution price may be significantly different from the stop price, if the market is moving rapidly.
·         Stop orders may be triggered by a short-lived, dramatic price change. During periods of volatile market conditions, the price of a stock can move significantly in a short period of time and trigger an execution of a stop order (and the stock may later resume trading at its prior price level). Investors should understand that if their stop order is triggered under these circumstances, their order may be filled at an undesirable price, and the price may subsequently stabilize during the same trading day.
·         Sell stop orders may exacerbate price declines during times of extreme volatility. The activation of sell stop orders may add downward price pressure on a security. If triggered during a precipitous price decline, a sell stop order also is more likely to result in an execution well below the stop price.
·         Placing a “limit price” on a stop order may help manage some of these risks. A stop order with a “limit price” (a “stop limit” order) becomes a “limit order” when the stock reaches or exceeds the “stop price.” A “limit order” is an order to buy or sell a security for an amount no worse than a specific price (i.e., the “limit price”). By using a stop limit order instead of a regular stop order, a customer will receive additional certainty with respect to the price the customer receives for the stock. However, investors also should be aware that, because a sell order cannot be filled at a price that is lower (or a buy order for a price that is higher) than the limit price selected, there is the possibility that the order will not be filled at all. Customers should consider using limit orders in cases where they prioritize achieving a desired target price more than receiving an immediate execution irrespective of price.
·         The risks inherent in stop orders may be higher during illiquid market hours or around the open and close when markets may be more volatile. This may be of heightened importance for illiquid stocks, which may become even harder to sell at the then current price level and may experience added price dislocation during times of extraordinary market volatility. Customers should consider restricting the time of day during which a stop order may be triggered to prevent stop orders from activating during illiquid market hours or around the open and close when markets may be more volatile, and consider using other order types during these periods.
·         In light of the risks inherent in using stop orders, customers should carefully consider using other order types that may also be consistent with their trading needs.

Delivery Settings for Shareholder Materials

IB’s default setting for distributing shareholder communications (e.g., proxy materials and annual reports) from U.S. and Canadian issuers is electronic delivery.  Under this method the account holder will receive an email notice when information becomes available for a security they hold from our processing agent, Mediant Communications. This notification will provide the necessary links for accessing the information and voting through the Internet in lieu of receiving these documents via postal service. The technology which you will need to secure the information includes access to the Internet and a web browser supporting secure connections. In addition, you will need to be able to read the documents online and print a copy provided your system supports documents in a PDF format.


Other items of note:

 -  We recommend that you add the following addresses to your email address book to minimize the possibility of communications being routed to your junk folder or rejected by your email provider as spam:,,,
-  Issuers reserve the right, and are sometimes required by regulation, to send certain shareholder communications via postal mail regardless of the account holder’s preference for electronic delivery. This will most often be the case for interim or special meetings or for contested voting matters.
-  Account holders may withdraw their consent to electronic delivery and revert to postal delivery at any time by submitting a request through the Message Center located with Account Management.  Note that changes to delivery settings are not applied to shareholder materials where the record date has already been sent. Account holders may, therefore, continue to receive deliveries for certain securities via the existing method for a period of 2 to 4 weeks after requesting a change.

-  The information above applies solely to shareholder communications associated with U.S. and Canadian issuers. The delivery of communications for securities issued outside of these two countries is typically electronic, but managed directly by the issuer or its agent (i.e., not Mediant).

¿Cuales son las fechas claves en relación con los dividendos de acciones?


Las fechas claves en relación con los dividendos de acciones son las siguientes:

1. Fecha de declaración: fecha en la que la junta de directores de la empresa aprueba el pago de dividendos y designa la fecha de pago y la fecha de cierre de registro.

2. Fecha de cierre de registro: la fecha que determina los accionistas con derecho a recibir el pago del dividendo. Debe ser titular de acciones al final del día de la fecha del cierre de registro para recibir el dividendo.

3. Fecha exdividendo: la fecha en la que las acciones se negociarán sin el derecho a recibir el dividendo. Debido a que la mayoría de las operaciones en acciones en Estados Unidos se liquidan de forma regular, es decir tres días hábiles tras la operación, una persona física debe comprar las acciones tres días hábiles antes de la fecha de cierre de registro para cualificarse para el dividendo. La fecha exdividendo es, por lo tanto, dos días hábiles anterior a la fecha de cierre de registro.

4. Fecha de pago: fecha en la que el dividendo declarado se paga a todos los accionistas que tengan acciones en la fecha de cierre de registro.

Inversiones cualificadas para cuentas RSP y TFSA

La normativa de la Canadian Revenue Agency (“CRA”) impone restricciones sobre los tipos de posiciones que pueden mantenerse en cuentas RSP y TFSA con elegibilidad limitada para aquellas que cumplan la definición de “Inversión Cualificada”. Las posiciones mantenidas en dichas cuentas que no cumplan con esta definición se referirán como "inversiones no cualificadas" y estarán sujetas a un impuesto CRA igual al 50% del valor justo de mercado de la propiedad en el momento en que se adquirió o se convirtió en no cualificada.

Las inversiones no cualificas incluyen los siguientes instrumentos: inversiones en propiedades, incluidos capital, certificados de inversión garantizada (GIC), bonos gubernamentales y corporativos, fondos mutuos y valores cotizados en un mercado designado. Tenga en cuenta que ciertas inversiones, aunque sean cualificadas, pueden no ser ofrecidas por IB debido al propio tipo de producto o no se admite el mercado designado.1

Las inversiones no cualificadas incluyen cualquier propiedad que no esté clasificada como Inversión Cualificada. Ejemplos de esto incluyen la negociación en acciones en NEX en Canadá, así como acciones en PINK y OTCBB en los Estados Unidos.

Si desea información adicional, consulte los siguientes enlaces de la página web de CRA:


1 Tenga en cuenta que aunque IB no ofrece acceso al mercado de valores canadiense (CNSX), las acciones que se coticen en ese mercado designado pueden transferirse y mantenerse en cuentas RSP o TFSA mantenidas en IB, pero deben transferirse a otra cuenta para el cierre.

Qualified Investments in RSP & TFSA Accounts

Canadian Revenue Agency (“CRA”) regulations place restrictions upon the types of positions that may be held in RSP and TFSA accounts with eligibility limited to those meeting the definition of a “Qualified Investment”. Positions held in such accounts that do not meet this definition are referred to as “Non-Qualified Investments” and are subject to a CRA tax equal to 50% of the fair market value of the property at the time it was acquired or it became Non-Qualified.

Qualified Investments include the following instruments: an investment in properties, including money, guaranteed investment certificates (GICs), government and corporate bonds, mutual funds, and securities listed on a designated stock exchange.  Note that certain investments, while Qualified, may not be offered by IB due to the product type itself or its designated exchange not being supported.1

Non-Qualified investments include any property that is not is not classified as a Qualified Investment.  Examples include stocks trading on NEX in Canada, as well as on PINK and OTCBB shares in the US.

For additional information, please refer to the CRA website links below:


1 Note that while IB does not offer access to the Canadian Securities Exchange (CNSX), shares which are listed on that designated exchange may be transferred into and held in a RSP or TFSA account held with IB, but must be transferred elsewhere to close.

Determining Buying Power

Buying power serves as a measurement of the dollar value of securities that one may purchase in a securities account without depositing additional funds. In the case of a cash account where, by definition, securities may not be purchased using funds borrowed from the broker and must be paid for in full, buying power is equal to the amount of settled cash on hand. Here, for example, an account holding $10,000 in cash may purchase up to $10,000 in stock.

In a margin account, buying power is increased through the use of leverage provided by the broker using cash as well as the value of stocks already held in the account as collateral. The amount of leverage depends upon whether the account is approved for Reg. T margin or Portfolio Margin. Here, a Reg. T account holding $10,000 in cash may purchase and hold overnight $20,000 in securities as Reg. T imposes an initial margin requirement of 50%, which translates to buying power of 2:1 (i.e., 1/.50). Similarly, a Reg. T account holding $10,000 in cash may purchase and hold on an intra-day basis $40,000 in securities given IB’s default intra-day maintenance margin requirement of 25%, which translates to buying power of 4:1 (i.e., 1/.25).

In the case of a Portfolio Margin account, greater leverage is available although, as the name suggests, the amount is highly dependent upon the make-up of the portfolio. Here, the requirement on individual stocks (initial = maintenance) generally ranges from 15% - 30%, translating to buying power of between 6.67 – 3.33:1. As the margin rate under this methodology can change daily as it considers risk factors such as the observed volatility of each stock and concentration, portfolios comprised of low-volatility stocks and which are diversified in nature tend to receive the most favorable margin treatment (e.g., higher buying power).

In addition to the cash examples above, buying power may be provided to securities held in the margin account, with the leverage dependent upon the loan value of the securities and the amount of funds, if any, borrowed to purchase them. Take, for example, an account which holds $10,000 in securities which are fully paid (i.e., no margin loan). Using the Reg. T initial margin requirement of 50%, these securities would have a loan value of $5,000 (= $10,000 * (1 - .50)) which, using that same initial requirement providing buying power of 2:1, could be applied to purchase and hold overnight an additional $10,000 of securities. Similarly, an account holding $10,000 in securities and a $1,000 margin loan (i.e., net liquidating equity of $9,000), has a remaining equity loan value of $4,000 which could be applied to purchase and hold overnight an additional $8,000 of securities. The same principals would hold true in a Portfolio Margin account, albeit with a potentially different level of buying power.

Finally, while the concept of buying power applies to the purchase of assets such as stocks, bonds, funds and forex, it does not translate in the same manner to derivatives. Most securities derivatives (e.g., short options and single stock futures) are not assets but rather contingent liabilities and long options, while an asset, are short-term in nature, considered a wasting asset and therefore generally have no loan value. The margin requirement on short options, therefore, is not based upon a percentage of the option premium value, but rather determined on the underlying stock as if the option were assigned (under Reg. T) or by estimating the cost to repurchase the option given adverse market changes (under Portfolio Margining).

Determining Tick Value

Financial instruments are subject to minimum price changes or increments which are commonly referred to as ticks. Tick values vary by instrument and are determined by the listing exchange. IB provides this information directly from the Contract Search tool on the website or via the Trader Workstation (TWS). To access from TWS, enter a symbol on the quote line, right click and from the drop-down window select the Contract Info and then Details menu options.  The contract specifications window for the instrument will then be displayed (Exhibit 1).

To determine the notional value of a tick, multiple the tick increment by the contract trade unit or multiplier.  As illustrated in the example below, the LIFFE Mini Silver futures contact has a tick value or minimum increment of .001 which, when multiplied by the contract multiplier of 1,000 ounces, results in a minimum tick value of $1.00 per contract.  Accordingly, every tick change up or down results in a profit or loss of $1.00 per LIFFE Mini Silver futures contract.


Exhibit 1

SPY - Dividend Recognition

Unlike the case of a stock, in which a dividend is taxable in the year in which it is paid, the SPDR S&P 500 ETF Trust (Symbol: SPY) represents itself as a Regulated Investment Company and its dividend is deemed taxable in the year in which the record date is determined.  As such, SPY dividends declared in either October, November or December and payable to shareholders of record on a specified date in one of those months will be considered taxable income income in that year despite the fact that such dividend will generally be paid in January of the following year.

Margin Treatment for Foreign Stocks Carried by a U.S. Broker

As a U.S. broker-dealer registered with the Securities & Exchange Commission (SEC) for the purpose of facilitating customer securities transactions, IB LLC is subject to various regulations relating to the extension of credit and margining of those transactions. In the case of foreign equity securities (i.e., non-U.S. issuer), Reg T. allows a U.S. broker to extend margin credit to those which either appear on the Federal Reserve Board's periodically published List of Foreign Margin Stocks, or are deemed to have a have a "ready market" under SEC Rule 15c3-1 or SEC no-action letter.

Prior to November 2012, "ready market" was deemed to include equity securities of a foreign issuer that are listed on what is now known as the FTSE World Index. This definition was based upon a 1993 SEC no-action letter and was premised upon the fact that, while there may not have been a ready market for such securities within the U.S., the securities could be readily resold in the applicable foreign market.  In November of 2012, the SEC issued a follow-up no-action letter ( which expanded the population of foreign equity securities deemed to have a ready market to also include those not listed on the FTSE World Index provided that the following four conditions are met:


1. The security is listed on a foreign exchange located within a FTSE World Index recognized country, where the security has been trading on the exchange for at least 90 days;

2. Daily bid, ask and last quotations for the security as provided by the foreign listing exchange are made continuously available to the U.S. broker through an electronic quote system;

3. The median daily trading volume calculated over the preceding 20 business day period of the security on its listing exchange is either at least 100,000 shares or $500,000 (excluding shares purchased by the computing broker);

4. The aggregate unrestricted market capitalization in shares of the security exceed $500 million over each of the preceding 10 business days.

Note: if a security previously meeting the above conditions no longer does so, the broker is provided with a 5 business day window after which time the security will no longer be deemed readily marketable and must be treated as non-marginable.

Foreign equity securities which do not meet the above conditions, will be treated as non-marginable and will therefore have no loan value. Note that for purposes of this no-action letter foreign equity securities do not include options.
