VOLUME – Calculation of Shares Traded

At first glance, the number of shares executed in a given time period would seem to be a straightforward calculation. The simplest definition of volume is the number of shares traded from one point in time to another point in time. However, several variables affect the calculation.

Market conditions may cause a calculation of volume to differ among data providers. For example, the two plans that manage the US Consolidated equities market have different number of, and definition for, trade reporting codes. In addition, data distributors often include variables such as odd lots, corrections, cash trades, or pre-/post-market trades in the volume calculation.

Numbers can become more visible in light volume or over time. For example, what was volume as of 09:37?

Time Symbol Quantity Price
9:35 XYZ 1000 19.90
9:36 XYZ -1000 19.90
9:37 XYZ 1000 19.80

Depending on the distributor, the volume at 09:37 could be:

  • 1000 shares if the distributor corrects the volume for corrections
  • 2000 shares if the distributor only counts positive numbers
  • 3000 shares if the distributor reflects the total of all prints expressed as a positive number

This may be a simplified example, but understanding how a distributor calculates volume will help the volume calculation serve as an indicator of market direction.

Alternative Streaming Quotes for US Equities


The SEC Vendor Display Rule requires that brokers give clients access to the NBBO at the point of order entry. In order to provide users with free live streaming market data, we cannot display this free stream when entering an order without the client subscribing to the paid NBBO.


Under the Rule 603(c) of Regulation NMS (Vendor Display Rule), when a broker is providing quotation information to clients that can be used to assess the current market or the quality of trade execution, reliance on non-consolidated market information as the source of that quotation would not be consistent with the Vendor Display Rule.

Therefore and according to FINRA's enforcement of the SEC rule, any client of a broker that is purchasing real-time quotes must buy the NBBO real-time services when making trading decisions.

All clients have access to streaming US equity quotes from the four CBOE exchanges and IEX at no charge. Since this data does not include all markets, we cannot show this quote when entering parameters for a US stock quote. Order routing will not change based on what is shown on the screen. If one is subscribed to NBBO quotes or not, by default the trade will still take place with the assistance of the SMART order router designed to provide the best price for the order.

Please see the sample screenshots below from TWS Classic and TWS Mosaic for what occurs when placing an order without the NBBO streaming subscription for US equities.

FTSE Indices at IBKR

IBKR does not make available real-time index levels for indices published by the FTSE Group. This is due to the disproportionately high licensing fees FTSE would require of IBKR.

Affected indices are the FTSE 100 and the FTSE MIB 40.

You may instead refer to the “Last” prices for IBKR CFDs IBGB100 and IBIT40 respectively, which are the mid-points of the CFD quotes, and an accurate real-time reflection of traded prices for the futures contracts related to these indices.

Specifically, the Index CFD quotes are based on synthetic indices calculated by back-adjusting the price of the related near-month future for fair value.

In the futures market, fair value is the equilibrium price for a futures contract. It is the price at which an investor effectively pays the appropriate rate of interest, and is compensated for the dividends he forgoes by holding the future rather than the underlying shares. To create the synthetic indices, the fair value adjustment is reversed.

The result is not necessarily exactly the same value as the cash index, in particular because the future may trade above or below its fair value. But as noted above, it is an accurate real-time reflection of the markets related to the index.

While you cannot compare e.g. the IBGB100 directly to the FTSE 100 in TWS (since we do not display the latter), you can observe the relationship between other Index CFDs and cash indices by comparing, for example, the IBUS500 to the S&P 500 index.

Market Data - Minimum Equity Threshold


As a matter of policy, and to minimize the likelihood of a low-balance account falling out of margin compliance and being subject to forced liquidations, IBKR enforces a minimum equity requirement as a prerequisite for subscribing to real-time market data.

This requirement works as follows: Once an account has met the minimum equity requirement necessary to subscribe to data, it is allowed to maintain those subscriptions as long as it has the funds available to pay for those subscriptions and its equity remains above the minimum level.  Once equity falls below the minimum level, it will be required to restore equity to at least the minimum level before resuming subscriptions.

While clients are not required to subscribe to real-time quotes through IBKR as a condition of trading, those that do are encouraged to maintain equity well above the maintenance level to avoid any fluctuations that would impair continuity of subscriptions.

Minimum equity thresholds vary by account type and are outlined in the table below.



Market Data Equity Thresholds1
Account Type


Individual (unless listed below) $500

Individual client of IB India $100

1 Denominated in USD, but applied in USD equivalent for accounts with a Base Currency other than USD.

2 Represents amount necessary to qualify for subscription renewal in any month following initiation.

Connecticut Sales and Use Tax

The state of Connecticut imposes a sales and use tax which is applicable to online access to information including all data and access fees.

The tax rate as of 2017 is 1% and is applicable to clients with the state of legal residency of Connecticut or a Connecticut permanent/resident address.

The sales and use tax will be applied to all research and market data subscriptions as well as special connections such as VPN, IB Gateway, Extranet and Dedicated Leased Lines.

The sales and use tax will be passed through to client accounts at the time of the subscription billing. The tax is only applicable if a monthly fee is charged, therefore should an account receive a waiver the sales and use tax will similarly be waived.



Delayed Market Data Timing


Market data vendors typically offer exchange data in two categories, real-time and delayed. Real-time market data is disseminated as soon as the information is publicly available. Delayed market data is on a time lag that is usually 10-20 minutes behind real-time quotes.

Some exchanges allow delayed data to be displayed without any market data subscription, free of charge. A list of the exchanges we provide delayed data for at no cost and without formal request (i.e., the delayed data will be displayed upon entry of the product symbol on the trading platform) are outlined in the table below. The table also includes the corresponding real-time subscription, the fees for which are posted on IBKR's public website

Please Note:

  • Delayed quotes are not provided for U.S. stocks in IBLLC accounts or any IBKR account where the client resides in the U.S. due to FINRA regulations.
  • Delayed quotes should be used for indicative purposes and not necessarily for trading. The times mentioned may be subject to further delays without notice.

Chicago Personal Property Tax

Chicago has a personal property tax which applies to a non-possessory computer lease by a Chicago resident. The Chicago tax authorities have ruled that tax is to be applied in cases where a customer pays for electronic research/use of an interactive site. The passive receipt or streaming of information is not subject to the tax.

Clients whose permanent residential address or principal business address is Chicago will have this tax passed through to their accounts.

The tax rate, as of October 2017, is 9%. The tax will be charged on the research and news feeds a client is subscribed to. Should a research and news feed be eligible to a waiver based upon commissions generated, the tax will not be applied.

As of October 2017, research and news subscriptions which would be subject to the tax would include

Base IBIS Research Platform and the IBIS Research Essentials Subscription Bundle
Dow Jones News Service
Dow Jones Real Time News
US Press Release Feed
Reuters Global Newswire
Reuters StreetEvents Calendars
Reuters Fundamentals
Reuters Basic Newfeed
Morningstar Equity, ETF and Credit Reports
Wall Street Horizons
Zacks Equity Research Reports

The above list is provided on a best efforts basis and is subject to change. Clients will be responsible for any pass through tax regardless of any discrepancy from the list provided above.
