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.

Note, these 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.

La vista previa de orden de WebTrader muestra solo el equivalente de los valores postnegociación de TWS.


Предпросмотр ордера / Проверка маржи


Функция "Предпросмотр ордера/влияния на маржу" позволяет увидеть прогноз стоимости, комиссий и влияния на маржу, прежде чем Вы отправите ордер. Эта возможность доступна как в TWS, так и WebTrader, однако TWS предлагает более высокий уровень детализации.

Trader Workstation (TWS)

Функция TWS "Проверить маржу" позволяет рассмотреть влияние создаваемого ордера на маржу отдельно от уже имеющихся позиций, а также отображает новые маржинальные требования на основании предполагаемого исполнения ордера. Сообщаются ключевые показатели маржи, включая начальные и минимальные требования, а также общая сумма капитала с кредитом. Чтобы воспользоваться этой функцией, наведите курсор на строку ордера, щелкните по ней правой кнопкой мыши и выберите Проверить маржу в открывшемся меню.

Пример: Покупка фючерса 1 ES June 2012 @ 1387.25


В первом разделе предпросмотра ордера отображается бид, аск и последняя цена ценной бумаги.


Второй раздел содержит базовое описание ордера.


Раздел "Сумма" (Amount) отражает стоимость ордера, а также расчет применимых комиссий.


Раздел "Влияние на маржу " содержит следующие пункты;

Текущ. (Current) = Текущие показатели счета, не включающие отправляемый ордер.

Изменение (Change) = Влияние ордера при отправке, без учета каких-либо позиций на счете.

После завершения торгов (Post Trade) = Прогнозируемые показатели счета после отправки/исполнения ордера и его последующего включения в портфель.



Предпросмотр в WebTrader отображает только информацию, доступную в пункте "После завершения торгов" в TWS.


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.

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.

Anteprima ordine/Verifica margine


La funzione Anteprima ordine/Verifica margine offre la possibilità di verificare il costo e l'impatto sulle commissioni e sul margine previsti per uno specifico ordine prima della sua trasmissione. Sebbene questa funzione sia disponibile sia in TWS sia in WebTrader, la versione per TWS è quella che offre più dettagli.

Trader Workstation (TWS)

La funzione Verifica margine di TWS offre la possibilità di isolare l'impatto sul margine dell'ordine proposto dalle posizioni in essere del dato utente e, inoltre, mostra il nuovo requisito di margine partendo dal presupposto che l'ordine venga eseguito.

Aperçu de l'ordre / Impact sur la marge


La fonctionnalité Aperçu de l'ordre/impact sur la marge offre la possibilité de voir le coût projeté, la commission et l'impact sur la marge d'un ordre avant sa transmission. Cette fonctionnalité est disponible à la fois dans TWS et WebTrader. La version de TWS est plus détaillée.
