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.

Risk Navigator: Alternative Margin Calculator


IB routinely reviews margin levels and will implement changes which serve to increase requirements above statutory minimums as market conditions warrant.  To assist clients with understanding the effects of such changes on their portfolio, a feature referred to as the "Alternative Margin Calculator" is provided within the Risk Navigator application. Outlined below are the steps for creating a “what-if” portfolio for the purpose of determining the impact of such margin changes.

Step 1: Open a new “What-if” portfolio

From the Classic TWS trading platform, select the Analytical Tools, Risk Navigator, and then Open New What-If menu options (Exhibit1).

Exhibit 1

From the Mosaic TWS trading platform, select New Window, Risk Navigator, and then Open New What-If menu options.

Step 2: Define starting portfolio

A pop-up window will appear (Exhibit 2) from which you will be prompted to define whether you would like to create a hypothetical portfolio starting from your current portfolio or a newly created portfolio. Clicking on the "yes" button will serve to download existing positions to the new “What-If” portfolio.

Exhibit 2

Clicking on the "No" button will open up the “What – If” Portfolio with no positions.

Risk Dashboard

The Risk Dashboard is pinned along the top of the product tab-sets, and is and is available for what-if as well as active portfolios. The values are calculated on demand for what-if portfolios. The dashboard provides at-a-glance account information including:

1) Net Liquidation Value: The total Net Liquidation Value for the account
2) P&L: The total daily P&L for the entire portfolio
3) Maintenance Margin: Total current maintenance margin
4) Initial Margin: Total initial margin requirements
5) VAR: Shows the Value at risk for the entire portfolio
6) Expected Shortfall (ES): Expected Shortfall (average value at risk) is expected return of the portfolio in the worst case


Alternative Margin Calculator

The Alternative Margin Calculator, accessed from the Setting menu and clicking on the Margin Mode (Exhibit 3), shows how the margin change will affect the overall margin requirement, once fully implemented.

Exhibit 3


Step 3: Selecting Margin Mode Settings

A pop-up window will appear (Exhibit 4) entitled Margin Mode Setting. You can use the drop-down menu in that window to change the margin calculations from Default (being the current policy) to the new title of the new Margin Setting (being the new margin policy). Once you have made a selection click on the OK button in that window.

Exhibit 4

Once the new margin mode setting is specified, the Risk Navigator Dashboard will automatically update to reflect your choice. You can toggle back and forth between the Margin Mode settings. Note that the current Margin Mode will be shown in the lower left hand corner of the Risk Navigator window (Exhibit 5).

Exhibit 5


Step 4: Add Positions

To add a position to the "What - If" portfolio, click on the green row titled "New" and then enter the underlying symbol (Exhibit 6), define the product type (Exhibit 7) and enter position quantity (Exhibit 8)

Exhibit 6


Exhibit 7


Exhibit 8


You can modify the positions to see how that changes the margin. After you altered your positions you will need to click on the recalculate icon () to the right of the margin numbers in order to have them update. Whenever that icon is present the margin numbers are not up-to-date with the content of the What-If Portfolio.


20-Minute Reconnect Grace Period, Unless Fingerprint/PIN Device Lock is Enabled

We recently introduced 30-hour Extended Trading access for mobile users (see the Android or iOS release notes).

For your protection, this feature requires that fingerprint or PIN/Pattern security be enabled on your mobile device. If not enabled, a 20-minute inactivity grace period applies, after which you are disconnected from your trading session and logged into Read-Only mode (which can be disabled), and must perform a full login for trading access.
While we remain diligent in our efforts to keep your account protected, we understand that good security is also about striking a balance between safety and convenience. If you feel strongly that this change adds undue burden to your trading setup - we'd like to hear from you.  Please vote on the Enhancement Request available through our Features Poll.


IB TWS for Mobile - Extended Trading Access


Get extended trading access in IB TWS for Mobile when you enabled fingerprint security on your device.

Once logged in to TWS for Mobile, all users have a 20-minute grace period during which they can take a call or use another app and still retain full access to their trading session without having to perform a full login (username/password + second factor authentication). After this grace period, users who have fingerprint security enabled on their device will enjoy secure trading for up to 30 hours without having to complete the full login.

When you enable a fingerprint to unlock your device, you are automatically enrolled for TWS Fingerprint authentication. This means that once you log in to TWS, you are able to securely re-access your trading session for up to 30 hours using just your fingerprint as authentication. If your fingerprint authentication fails or if you tap “Cancel,” you will be logged in to read-only mode. After 30 hours without using fingerprint authentication, you will be required to complete a full login. This means that if you access mobile TWS at least every 30 hours, you can maintain your trading access for an entire week without a full login. For added security, all mobile trading sessions are disconnected each Sunday at 1:00 AM local time, requiring you to complete a full login.
Users who use a PIN or pattern instead of a fingerprint to unlock their device will be able to re-access their trading session with this authentication for up to 12 hours before a full login is required.
If you do not want to enable the above forms of trading access and prefer to complete the full login process each time, disable “Secure reconnect” (Android) or "Auto-reconnect" (iOS) in IB TWS for Mobile Configuration.

How to adjust font size in TWS


By default, Trader Workstation (TWS) is designed to display in a font size and style which can be read comfortably for the average user across various screen sizes and resolutions. With the advent of new technologies, there has been an exponential push to make monitors with higher display sizes and your layout may need to be further adjusted manually. This document serves to explain how to manually adjust the font size for TWS.


To adjust font size throughout TWS:

  1. From the Anchor window, click the Font Size Adjustment icon.
  2. Check the button Adjust window & column widths to ensure all windows will resize automatically to keep the same font:window ratio. (If unchecked, only font size will change but window size will remain the same).
  3. Click the button Smaller or Larger until the font size is correct.
    Notice that the font size will change immediately as you click the button.
  4. Click the Font Size Adjustment icon   when done.

Note: It is possible that currently not all windows will be adjusted in the same way.

Ordervorschau/Marginauswirkung prüfen


Die Funktion „Ordervorschau/Marginauswirkung prüfen“ bietet die Möglichkeit, die voraussichtlichen Kosten und Provisionen und die Marginauswirkung einer Order zu überprüfen, ehe Sie diese übermitteln. Diese Funktion steht sowohl in der TWS als auch im WebTrader bereit, wobei die TWS-Variante mehr Details bereitstellt.

Trader Workstation (TWS)

Die TWS-Funktion „Margin überprüfen“ ermöglicht es Ihnen, die Marginauswirkung einer bestimmten geplanten Order von den bestehenden Positionen zu isolieren und zudem die neue Margin-Anforderung anzuzeigen, die bei Ausführung der betreffenden Order gelten würde. Die wichtigsten Marginwerte, wie zum Beispiel die Anforderungen für den Ersteinschuss und Mindesteinschuss, sowie das Eigenkapital mit Beleihungswert, werden hier ausgewiesen. Wenn Sie diese Funktion verwenden möchten, richten Sie den Mauszeiger auf eine Orderzeile, führen Sie einen Rechtsklick aus und wählen Sie die Option „Margin überprüfen“ aus dem Drop-Down-Menü aus.

Beispiel: Kauf von 1 ES Juni 2012 Future @ 1387.25


Im ersten Abschnitt der Ordervorschau werden der Geldkurs, der Briefkurs und der letzte Handelskurs des Wertpapiers angezeigt.


Im zweiten Abschnitt sehen Sie die wichtigsten Orderdetails.


Im Kontoabschnitt sehen Sie den Wert der Order sowie einen Schätzwert für die anfallenden Provisionen.


Der Abschnitt Marginauswirkung zeigt eine Aufstellung der folgenden Werte an:

Aktuell = Die aktuellen Marginwerte, ohne Berücksichtigung der Order, die platziert werden soll.

Veränderung = Die Auswirkung der Order, wenn diese übermittelt wird, ohne Einbeziehung jeglicher im Konto bestehender Positionen.

Nach Ausführung = Die Kontowerte, die sich voraussichtlich nach Übermittlung und Ausführung der Order und Aufnahme der Position ins Portfolio ergeben.



In der WebTrader-Ordervorschau sehen Sie lediglich äquivalente Werte zum Abschnitt „Nach Ausführung“ aus der TWS.


IEX Discretionary Peg Order


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

D-Peg™ combines elements of Midpoint Peg, Primary Peg, and traditional discretionary order types.
Information about slow and predictable changes in the NBBO are detected in IEX's Crumbling Quote Indicator and provides D-Peg™ orders with an instruction to stop seeking access to liquidity at a more aggressive price until the quote returns to a stable state.


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

Select the REL order type from the Order Type drop down menu.


Step 3

Click on the Miscellaneous tab (Misc.) and at the bottom there will be a checkbox for "Discretionary up to limit". Check this box. The price that you set in the Limit Price field will be used at the discretionary price on the order.



Step 4 

Hit Preview to view the Order Preview window.

Additional details regarding this quote service is provided below. 


The Snapshot quote includes the following data:        

  • Last price
  • Last size
  • Last exchange
  • Current bid-ask

1Delayed 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.

2Cost is per snapshot quote request and will be assessed in the Base Currency equivalent, if not USD.



  • Accounts must maintain the Market Data Subscription Minimum and Maintenance Equity Balance Requirements in order to qualify for Snapshot quotes.
  • The Users must operate TWS Build 976.0 or higher to access Snapshot quote functionality.



  • Clients will receive $1.00 of snapshot quotes free of charge each month. Free snaphots may be applied to either U.S. or non-U.S. quote requests and charges will be applied, without additional notice, once the free allocation has been exhausted. Clients may review their snapshot usage as of the close of each business day via the Client Portal.
  • Quote fees are assessed on a lag basis, generally in the first week after the month in which Snapshot services were provided. Accounts which do not have sufficient cash or Equity With Loan Value to cover the monthly fee will be subject to position liquidations.
  • The monthly fee for snapshots will be capped at the related streaming real-time monthly service price. At which time the streaming quotes will be provided at no additional cost for the remainder of the month.  The switch to streaming quotes will take place at approximately 18:30 EST the following business day after reaching the snapshot threshold. At the close of the month, the streaming service will automatically terminate and the snapshot counter will reset. Each service is capped independently of the others and quote requests for one service cannot be counted towards the cap of another. See table below for sample details.

Dokumentation zu IB Hosts und Ports


Die TWS verbindet sich mit IBKR-Servern über die Ports 4000 und 4001 und falls SSL verwendet wird, wird sie über keinen anderen Port aktiv sein. Falls Sie einen Proxy-Server verwenden, muss es sich um einen transparenten mit sowohl eingehenden als auch ausgehenden offenen Ports handeln, damit die TWS ordnungsgemäß funktionieren kann.

Nachstehend finden Sie alle Gateways sowie den zugehörigen Destination-Host, der unter Umständen von der TWS verwendet wird, wenn Sie unsere Dienste nutzen. Bitte gewähren Sie den Zugang zu diesen Hosts.

Ob Ihre Verbindung eine besondere Einrichtung erfordert bzw. korrekt konfiguriert wurde, können Sie am einfachsten herausfinden, indem Sie die Testseite von IBKR verwenden, die einen dynamischen Test Ihrer Netzwerkverbindung zu unseren wichtigsten Trading- und Marktdatenservern ermöglicht. Falls Sie „Erfolg“ (success) als Rückmeldung erhalten, müssen Sie nichts weiter unternehmen. Falls die Rückmeldung „Fehlgeschlagen“ (failure) lautet, empfehlen wir, eine Ausnahme für die neuen Hosts zur Konfiguration Ihres Netzwerks hinzuzufügen oder Ihre Änderungen zu prüfen.

Hinweis: Falls Ihr Netzwerk einen Browser-Proxy verwendet, ist es möglich, dass die Testseite ein fälschlich positives Ergebnis ausgibt. In diesem Fall, oder wenn Sie nicht genau wissen, wie Ihre Netzwerkeinrichtung aussieht, sollten Sie sich an Ihren Netzwerkadministrator wenden. Dieser kann Ping- und Telnet-Tests zu den nachstehend aufgeführten Hosts durchführen, um die Konformität mit den Verbindungsanforderungen zu überprüfen.
























1: Standardkommunikation: TCP-Port 80 | SSL-Kommunikation: TCP-Port 443.

2: Dieser IB-Serverhost unterstützt keine Ping-Anfragen.

Wichtiger Hinweis: Falls Sie auf das Client Portal von einem Unternehmensnetzwerk aus zugreifen, bei dem der Internetzugang über einen Lastenausgleich bereitgestellt wird, ist es möglich, dass Sie Fehlermeldungen zu abgelaufenen/ungültigen Sitzungen und/oder fehlenden Webinhalten im Zuge oder nach der Login-Phase erhalten. Das Lastenausgleichsmodul leitet Ihre abgehenden Verbindungen über zwei oder mehrere Netzwerkoberflächen weiter, um die Netzwerkauslastung auszugleichen. Aufgrund dieses Mechanismus erreichen Ihre HTTP-Anfragen unsere Systeme aus unterschiedlichen IP-Adressen und machen Ihre Client-Portal-Sitzung somit ungültig.
In diesem Szenario bitten wir Sie, als Lösung Ihren Netzwerkadministrator oder IT-Abteilung Ihre Maschine/Ihr Gerät dahingehend zu konfigurieren, dass das Lastenausgleichsmodul umgangen wird. Dies wird dazu beitragen, dass Ihre Sitzung gültig und aktiv bleibt.
