First, be sure that you are logged into the correct version of TWS; i.e. If you read about a feature in the TWS Beta notes, you must log into the TWS Beta version to use it. To find features within TWS, use the "Help/Ticker Lookup" search box in the upper right corner of both Mosaic and Classic TWS.
The nightly log off is required for maintenance and cannot be disabled. However, you can modify the log off time from the Lock and Exit page of Global Configuration.
Find margin information for options on the Options tab of the Margin page.
You need to set the timing to "Allow order to be activated, triggered or filled outside of regular trading hours." You can define this setting from the Timing section of the Order Preset for a specific asset type, or on a per-order basis from the Time in Force field checkbox "Fill outside RTH.". If outside regular trading hours is not available for the specific order you are submitting, you will not be allowed to populate the checkbox.

Find download instructions and the necessary files on the Installation Instructions page.
If you have a slower computer or Internet connection, we recommend that you use the standalone version of TWS.
If you use the browser-based version, you can access TWS from any internet PC, and do not have to manually update to get the latest version. Both require that you install the minimum recommended version of Java..
Go to the Java Upgrade Instructions page and select the Windows or Mac operating system. Follow instructions for upgrading the Java plugin. Note that if you want to upgrade to a newer Java version, you must first remove the existing plugin and then install the upgraded version.
The beta release is a pre-production version of an upcoming release that allows you to actively trade while you test new features. You must deliberately elect to use the beta at your own risk when you log in. Since the beta is under construction until production release, we welcome your input on its performance. The beta will be promoted to production after it has been tested both in-house and externally over a specified time period. Please note that although the software is "in beta," you are still trading your IB account and are responsible for all transactions.
The login page includes links to both the beta and production release notes. These notes briefly describe new features that have been added and problems that have been fixed.
If you are running the standalone version, the update wizard will automatically check for TWS updates each time you log in to your computer. You can also manually check for updates from the Start menu by selecting Programs and then Startup and clicking Check for TWS Updates. Customers running the browser-based version can get the most recent production release by selecting Trader Workstation Latest from the Login menu.
First, uninstall TWS by going to add/remove programs and removing TWS. You can then reinstall TWS from the TWS Software page.
You will receive this message for one of the following reasons:
IB has two distinct departments that handle specific types of TWS questions:
In the US, call 877-442-2757 during regular business hours for support.
You can also email us at email@example.com. Please include the following information:
You may experience problems with TWS if you are running the software without meeting the minimum system requirements. When troubleshooting problems, start by making sure that your computer meets our minimum system requirements.
A. Your Internet connection may drop off due to connectivity or Internet Service Provider (ISP)-based issues.
Consult our connectivity FAQ if you suspect if this is an issue.
B. This problem has also been known to occur with problematic Ethernet cards.
This may be due to a corrupted or improper install of TWS or the Java Applet.
Outdated or corrupted browsers can cause this to occur. Please upgrade or uninstall if necessary.
Or, your browser display settings may be preventing you from viewing the entire screen.
Your browser's cache may have a problematic page stored in it.
Dial-in customers or customers with a poor connection may periodically experience problems loading an applet through a browser. Browser download and installation of applets tend to stall on slower connections.
This typically occurs if:
Your ports are being blocked by either:
This may happen for a variety of reasons. Try the following:
This may happen for a couple of reasons. Try the following:
This indicates there is a problem with your network connection. Refer to our Network FAQ and your system Administrator to check for latency and network problems.
This may be the result of a problematic Ethernet card, or improper driver installation of display adapters. Download the latest version of your video drivers. You may have other PC problems which require immediate attention by an authorized PC technician.
This occurs when the page file becomes corrupt from a disk error.
To open the Control Panel, click Start, then select Settings>Control Panel.
With Windows XP, click Start>Control Panel.
Depending on the version of Windows you are using, its appearance may vary slightly from what we describe.
If you need to uninstall software, you should only do it from Add/Remove Programs window accessible from the Control Panel. Use this window to remove Trader Workstation or Java, or to repair your browser. When you uninstall a program, you will usually get a confirmation message ensuring that you do indeed want to remove the item that you have selected.
Note: Java does not support automatic upgrades. Before you upgrade Java, you must uninstall the current version.
Important: If you are uninstalling for reinstall purposes, Windows may ask you to restart your computer. DO NOT IGNORE THIS REQUEST. Shut down and restart your computer to allow files to be unlocked and removed from memory.
From the Trading menu on the IB website, select Trading Platforms and then choose the application your would like to install.
Whether you're downloading an encryption upgrade, a new browser or a service pack, all official Windows upgrades can be acquired from http://windowsupdate.microsoft.com/, shown above. Click on the "products update" link on the left-hand side, select the updates you wish to install, and follow the instructions.
Note: If you are running a non US-English version of Windows, you need to install the international plug-in.
Depending on the amount of data you are receiving (number of ticker symbols entered) most TWS sessions will function properly on a reliable 56k connection. However, the use of other network applications while you are using TWS may slow down your connection. The typical TWS client will utilize 6.5k/second to retrieve market data for 100 symbols of data.
TWS does not use any UDP.
TWS will function in a shared environment, provided that a reliable connection exists. The connection that a TWS machine receives must have sufficient bandwidth to operate. Users should take care when using NAT (Network Address Translation) and DHCP. While TWS will work if NAT and/or DHCP are configured properly, data loss and unpredictable behavior can result from improper configurations. For more information on NAT and DHCP, review the section below on those topics.
There are many types of broadband available. Cable, xDSL, Corporate Networks (T1, T3, Frac-T), Dial-on-demand ISDN and Satellite are all broadband solutions. All of these services provide much higher throughput (compared to a dial-in line) and typically use routers or special modems to become part of a hardwired network. Some services emulate this method rather than actually performing this way. Availability of different services may be limited in certain areas; contact vendors in your area for a list of available services.
TWS connects to our servers via ports 4000 and 4001; it will not function on any other port. To use TWS from behind a firewall, users should download the standalone version, and will be prompted during installation to specify proxy settings that will be used by TWS for all http requests. For details on configuring standalone TWS for use through a firewall, refer to Steps 7 and 8 in the Installation Instructions page.
Testing with these systems has proved inconclusive. Some satellite providers list trading software (or anything that requires a reliable connection) as an "at your own risk" practice. Customer feedback has indicated that satellite services are sometimes unreliable.
As with any type of connection, be sure the provider allows TCP/IP routing with open access to Internet service ports. TWS connects to our servers via port 4000 using a source port in the publicly addressable space above port 1024. Our servers listen on port 4000; it will not function on any other port. For users behind firewalls, the installed version of TWS includes provisions for using a specified outbound port.
Be aware of the protocols and network devices that may affect you. The following is information about your TWS connection that you or your Network Administrator will want to know when troubleshooting your connection to us.
DHCP (Dynamic Host Configuration Protocol) is a way of automatically assigning IP addresses. If your DHCP server is assigning a private address (addresses which are not associated with the Internet) the server may be doing NAT (Network Address Translation) to get to the outside Internet Depending on the particular configuration, the router or server may be trapping requests from our server to your computer.
TCP/IP is the basic protocol from an Internet service provider. This, along with DNS (Dynamic Name System) and basic socket access are all that is required for a "functioning Internet connection" and for running TWS software.
NAT (Network Address Translation) is one of the basic components behind home routers (and some professional private routers). Done properly this should be transparent; the address on the outside should translate to your internal (non-Internet) addresses without your PC knowing the specifics of the routing.
Extraneous network adapters and drivers which are not connected, are inoperative or unnecessary should be removed from your system. These can cause unpredictable network behavior.
Latency due to physical distance from your ISP, routing within your ISP's network, packet loss and many other factors can affect the reliable operation of your TWS. Please review the connectivity troubleshooting tips below to test the quality of your connection.
The Ping command will test the quality and latency of your connection. If it shows 4 round-trip reports without a reply (does not say not found, timed out, etc.) your connection is healthy. To use this, type ping gw1.ibllc.com at the command prompt. A healthy ping should look as follows:
If the ping results show excessive latency (>500ms), timeouts/packet loss, or no replies, a network problem exists between you and the IB network.
The tracert command is used to isolate routing issues. This will show you all of the "hops" from your connection to our network. A timeout, indicated by "*" or time above 200, indicates a slow or dead hop and may be a problem. Over 15 hops can also be a problem.
To look at a traceroute, type tracert gw1.ibllc.com at the command prompt.
The following are sample traceroutes. Included is an explanation and suggested course of action. This traceroute is an example of a healthy connection. The ping times and the number of hops are low (lower is better). No course of action required.
This is an example of a marginal connection. The ping times and number of hops are fairly high, but the connection should still be usable. Contact your ISP to see if this is a common occurrence. If this is what you can expect, you may want to shop around for another provider. Higher times indicate line latency (slowness) and the high (17) number of 'hops' results in a higher potential for outage, in the event that one of the providers involved experiences a problem.
The next example shows a network outage. The connection fails between hop 8 and 9. In the event that this occurs, you should contact your ISP and give them this information. These types of outages are very obvious and are the easiest for an ISP to troubleshoot.
The last example is possibly the hardest to troubleshoot and the most frustrating. The occasional timeout (marked with *s) appears several places in the traceroute. This indicates that intermittent packet loss is taking place. These types of errors are elusive and may not have been reported yet. Contact your ISP about this issue.
Not for TWS. IB does support HTTP proxies for WebTrader, but this application has limited capabilities.
IB supports proxies that can emulate open sockets.
Create a snapshot of your computer screen and e-mail it to IB.
Try logging in and testing with another computer that you know works (with the same account) to see if the problem is the same on both computers.
If you have multiple Accounts, try another one of your accounts on your machine. If you don't have a second account, try using our demo system, or having a friend try their account on your machine will help to determine if there is a common issue among accounts (or systems) and where that problem may be.
Trying both systems may indicate that the problem is with a component installed on your computer or somewhere else.
