Exchange name change

Overview:

Interactive Brokers is completing an effort to update and consolidate exchange names where appropriate. When this effort is complete, the following updates will be in effect:

GLOBEX and CMECRYPTO will be consolidated to a single exchange, ‘CME’
ECBOT will be updated to ‘CBOT’
COMEX listed metals (previously reflected as NYMEX) will be updated to exchange ‘COMEX’
NYMEX, no change

Given the breadth of products involved, we are migrating in four waves based on underlying products:

Key	Effective Trade Date	Products
Wave 1	October 30, 2022	GLOBEX: ZAR, LB, DA, IXE
Wave 2	November 6, 2022	GLOBEX: EMD, BRE, CHF, SOFR3, E7, NKD CMECRYPTO: BTCEURRR, ETHEURRR, MET
Wave 3	November 13, 2022	GLOBEX: All remaining products CMECRYPTO: All remaining products ECBOT: ZO, ZR, 2YY, 30Y NYMEX: ALI, QI, QC
Wave 4	December 4, 2022	ECBOT: All remaining products NYMEX: All remaining "Metal" products

I am trading via API, how does this impact me?

For API clients the only requirement would be to provide a new exchange name, for example: exchange=”CME”, for existing contracts for the affected exchanges.

Old exchanges names will no longer be available after the change.

More details can be found within our FAQs through the following link: Upcoming Exchange name Changes

Note: If you are using a third party software connected to TWS or IB Gateway and that software does not recognize the new contract definitions, please contact the third party vendor directly.

If you use RSA encryption in file exchange communication with Interactive Brokers, best practice requires that this key be backed up for security and retrieval purposes. Creating a backup is quick and ensures the longevity of your Key Pair.

Note: this tutorial assumes you have already set up a Key pair. If you need guidance to set up the Key pair please refer to this article, which is a prerequisite to the instructions below.

Please select one of the below links, according to your Operating System:

Windows
macOS

Windows

1. Launch the application Kleopatra and select the encryption key you want to transfer. Then right-click on the selection and choose Backup Secret Keys...

Note: Do NOT use Export..., as this will only export the public part of the Key while you need to have a backup of both public and private parts.

2. Select a folder of your preference (e.g. Desktop) and a file name of your preference (e.g. secret-key-KEYID.asc) for your backup copy. Then click Save.

3. Enter the passphrase you have set when you created the Key and click OK.

4. A pop-up will confirm the backup has been successfully created. Click OK.

macOS

1. On the machine where the encryption keys are stored, create a new folder (e.g., on your Desktop).

2. Launch the application GPG Keychain and select the encryption key you want to transfer. Please make sure that Sec/Pub is indicated in the Type column.

3. Click the icon Export on the top toolbar. In the field Where, select the folder you previously created. Make sure to check Include secret key in exported file and then click Save as illustrated in the above screenshot.

4. A backup copy of the key pair will be created in the folder you selected.

How to Set Up sFTP for Using Certificate Authentication on macOS

These instructions apply to users who are receiving their statements via sFTP. If you elected to receive your statements that way, you would first need to generate an RSA Key pair. If you need guidance to set up the Key pair, please refer to this article, which is a prerequisite to the instructions below.

Note: There are many sFTP Clients available for macOS, either licensed or freeware. In this procedure we will refer to FileZilla, which is free of charge, but you can use a different one. FileZilla for macOS can be downloaded here.

1. Once you have installed FileZilla, launch it.

2. Click on File in the top left and select Site Manager:

3. If you see an existing Interactive Brokers sFTP site in the list, jump directly to point 6. If you do not have such site configured yet, Click New Site and select SFTP – SSH File Transfer Protocol as Protocol:

4. Change Logon Type from Normal to Key File and click on Browse to select the corresponding Private Key file from the designated directory where it is saved.

5. Enter:

xfer.interactivebrokers.com in the Host field.
32 in the Port field.
The username given you by Interactive Brokers in the User field.

6. Click Connect. Once successfully connected, you will be able to drag files from the Remote site (right side panel) to the Local machine (left side panel). In this way you will download the files on your local machine.

Common issues and solutions

A. The Login Credentials Provided are Incorrect

Ensure the correct login details are being used to connect to the sFTP server. The username and password you are entering should match the ones you have received from the Reporting Integration Team.
Confirm you have configured your sFTP Client to use the Private Key file for the logon authentication (see step 4. of the above procedure.)

B. Server Refused Our Key

Try accessing the sFTP server using a different Client (FileZilla, WinSCP, CyberDuck, ect.)
Ensure the Private Key file being used to Authenticate the server login attempt is related to the Public Key you originally sent to the Reporting Integration Team.
Should the above checks be unable to resolve the issue, please generate a new RSA Public/Private Key pair and send only the Public part to the Reporting Integration Team, as per IBKB3842.

C. Connection Timed Out

In case you have an antivirus or a security software installed on your machine, make sure it is not blocking the FTP connection attempt. Normally, security software allows to set up exceptions for specific connections in order to whitelist them.
Verify that the public IP Address of the machine running the sFTP client, is the same you have originally provided to the Reporting Integration Team for being whitelisted. You can discover your public IP Address by searching the Internet for “what is my IP”. If your current IP Address is not the same you provided to us, please send it to our Reporting Integration Team for being whitelisted.
Ask your network administrator/s to confirm that your firewall allows both incoming and outgoing traffic from/to xfer.interactivebrokers.com on port TCP 32.
Should the above steps be unable to resolve the issue, please generate a new RSA Public/Private Key pair and send only the new Public part to our Reporting Integration Team, as per IBKB3842.

Меры предосторожности при отказе от "Системы безопасного входа"

Overview:

Владельцы счетов, отказавшиеся от "Системы безопасного входа" (Secure Login System, или SLS) IBKR, тем самым поступаются защитой, которую обеспечивает двухфакторная аутентификация. В таком случае мы настоятельно рекомендуем прибегать к альтернативным мерам предосторожности, одной из которых являются ограничения по IP-адресу. Выбирая эту настройку в "Портале клиентов", Вы сообщаете Interactive Brokers, что доступ к Вашим торговым платформам должен осуществляться только с указанного IP-адреса. Если у счета есть несколько уполномоченных трейдеров, то эти ограничения могут устанавливаться индивидуально для каждого из них главным пользователем счета.

Подготовка:

Прежде чем устанавливать ограничения по IP-адресу, Вам нужно:

Узнать свой WAN IP-адрес. Это IP-адрес, отображаемый при внешних интернет-соединениях; он отличается от Вашего локального IP-адреса (также называемого LAN IP-адресом). Если Вы ведете торговлю из офиса, то можете спросить WAN IP своего компьютера у системного администратора или работника отдела ИТ. Если Вы выходите в интернет посредством домашнего высокоскоростного/кабельного/спутникового соединения, то необходимую информацию можно выяснить у Вашего поставщика услуг (интернет-провайдера).
Убедиться, что Ваш IP-адрес статичен. Это означает, что у Вас всегда должен быть один и тот же IP-адрес, не меняющийся при перезагрузке роутера/модема или по прошествии определенного периода времени. Узнать, является ли Ваш адрес статичным, можно у того же человека, который сообщил Вам WAN IP-адрес.
Имейте в виду, что ограничения по IP начинают действовать не сразу. Наши системы применяют фильтры в ходе ночной перезагрузки. В зависимости от времени отправки запроса активация может занять до 24 часов. То же самое касается изменения или удаления ограничений. Просим учитывать это при планировании своих действий.
Ограничения по IP применяются ко ВСЕМ торговым платформам IBKR. Это не повлияет на "Портал клиентов" – он по-прежнему будет доступен с любого IP-адреса.

Примечание:

Обращаем внимание, что существуют технологии, позволяющие отображать ложный IP-адрес, и полная защита счета обеспечивается только при использовании двухфакторной аутентификации (ibkr.com/sls).

Если у Вас возникли вопросы, свяжитесь с центром технической поддержки IBKR.

Как установить ограничения по IP:

Войдите в Портал клиентов и нажмите на значок меню в левом верхнем углу.
В меню выберите Настройки, и затем Настройки пользователя. Далее нажмите на значок шестеренки (настройки) рядом с пунктом Ограничения по IP (IP Restrictions).
Вы увидите краткое описание этих ограничений. Чтобы установить новое ограничение, нажмите Добавить ограничение по IP (Add IP Restriction).
Выберите Трейдер в выпадающем меню и введите IP-адрес (в формате xxx.xxx.xxx.xxx), доступ с которого Вы хотите разрешить. Нажмите Далее.
Если Вы вошли в "Портал клиентов" без использования двухфакторной аутентификации, Вам на электронную почту придет письмо¹ с кодом подтверждения. Введите его в поле Номер подтверждения (Confirmation Number). Нажмите Далее, чтобы отправить запрос. Если Вы вошли в "Портал клиентов", используя устройство защиты, то сразу переходите к пункту 6.
В случае успеха Вы увидите подтверждение. Нажмите OK.
Система отобразит Ваши активные ограничения по IP. Если Вы хотите создать еще одно ограничение, снова нажмите Добавить ограничение по IP. В ином случае закройте этот раздел.

Торговля мелкими акциями при отказе от двухфакторной аутентификации

Клиенты, частично отказавшиеся от двухфакторной аутентификации и использующие ее только при доступе к "Порталу клиентов", должны активировать ограничения по IP-адресу, чтобы получить разрешение на торговлю мелкими акциями ("penny stocks").

Дополнительные рекомендации по защите Вашего компьютера и подключения

Находясь в окне входа в TWS, включите переключатель "Использовать SSL". Протокол SSL гарантирует защиту всей информации, которой Ваш компьютер обменивается с нашими серверами, с помощью 128-битного шифрования.
Используйте файрвол, чтобы предотвратить несанкционированный доступ к сервисам, уязвимым к внешнему воздействию через Вашу сеть или компьютер. При настройке файрвола обязательно убедитесь, что хосты/порты, указанные в разделе TWS ДЛЯ ПК статьи KB2816, разрешены.
Используйте антивирусные программы для удаления вирусов, которыми может быть заражен Ваш компьютер. Так как новые вирусы создаются постоянно, антивирус следует регулярно обновлять.
Используйте антишпионское ПО для распознавания и удаления программ-шпионов, которые способны собирать разные виды личных данных, следить за Вашей активностью в браузере и препятствовать контролю над Вашим компьютером. Многие современные антивирусы содержат встроенную защиту против таких вредоносных программ.
Избегайте использования публичных, незащищенных и чужих беспроводных подключений (Wi-Fi). Если Вам понадобилось подключиться к незащищенной сети (например, публичной точке Wi-Fi), не входите в свои финансовые учетные записи, включая счет в IBKR.

Примечания:

1. Если Вы не получили электронное письмо, убедитесь, что оно не попало в папку "Спам", а также добавьте адреса donotreply@interactivebrokers.com и help@interactivebrokers.com в список разрешенных отправителей. Затем Вы можете запросить отправку нового письма при помощи кнопки Отправить номер подтверждения заново.

Совместимость MetaTrader и Interactive Brokers

Overview:

Interactive Brokers (IBKR) обеспечивает клиентов бесплатным ассортиментом своих торговых платформ и поэтому не рекламирует и не предлагает системы или дополнительное ПО от других поставщиков. Тем не менее, поскольку основная торговая платформа IBKR, TraderWorkstation (TWS), поддерживает открытый программный интерфейс (API), некоторые сторонние разработчики создают свои собственные модули для ввода ордеров, построения графиков и выполнения других аналитических функций, работающие в комплексе с TWS и позволяющие производить сделки через IBKR. Такие приложения API, интегрируемые в TWS, публикуются независимо от нас, и мы не всегда знаем об их существовании, из-за чего мы открыли Площадку инвесторов - самостоятельное сообщество, объединяющее сторонних поставщиков, которые готовы предложить свои продукты и услуги клиентам IB и трейдерам с определенными нуждами.

Несмотря на то, что служба MetaQuotes Software не участвует в "Площадке инвесторов" IBKR, она предлагает представляющим брокерам приложение oneZero Hub Gateway, позволяющее использовать платформу MetaTrader 5 для торговли через счета IBKR^[1]. Заинтересованным лицам следует связаться с oneZero напрямую. Это можно сделать через функцию "Contact Us" в одном из разделов следующей страницы.

Примечание: Помимо oneZero Hub Gateway у нас также поддерживаются такие сторонние поставщики, как Trade-Commander, jTWSdata и PrimeXM, предлагающие ПО, которое соединяет MetaTrader 4/5 с TWS. Как и в случае с любыми другими сторонними приложениями, IBKR не имеет права предоставлять информацию или рекомендации касательно их совместимости или работы.

1: Служба oneZero недоступна для частных счетов. Дополнительные сведения о представляющих брокерах доступны здесь.

SEC Tick Size Pilot Program FAQs

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: Is the Tick Size Pilot program still ongoing?

A: On March 29, 2019 the data collection requirements under the National Market System (NMS) plan to implement a Tick Size Pilot Program (Tick Size Pilot) ended. As a result, the Pilot Security File and Change File will no longer be produced on a daily basis. At the conclusion of the pilot, a blank Tick Size Pilot Securities file will be produced and the Change File will be updated to show the deletion of securities from the Tick Pilot Size list.

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 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 3^rd 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 3^rd 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.

Q: Where can I find out more information?

A: See KB2752 or the FINRA website for additional details regarding the Pilot Program: http://www.finra.org/industry/tick-size-pilot-program

How to fix the error: "Library dbcapi.dll cannot be loaded"

Background:

TWS users may receive the following error message upon configuring TWS to use the eSignal data feed:

This error may appear for the following reasons:

Issue A - You are not using the 32 bit version of TWS and/or eSignal:

The 32-bit versions of both TWS and eSignal have to be installed for the integration to work. In the section below you will find the instructions for installing the 32-bit TWS.
