This is a notification and not a true error condition, and is expected on first establishing connection.Ī notification that connection to the Security definition data server is ok. Outside of the nightly IB server reset, this typically indicates an underlying ISP connectivity issue.Ī notification that connection to the market data server is ok. Indicates a connectivity problem to an IB server. Wait until the order has been fully processed before modifying it. If you attempt to modify an order before it gets processed by the system, the modification will be rejected. Unable to modify this order as it is still being processed. If a client application invokes when there is an active subscription started by a different client, the TWS will reject the new subscription request with this message. Unable to subscribe to account as the following clients are subscribed to a different account. If the client application attempts to subscribe to a second account without canceling the previous subscription, the new request will override the old one and the TWS will send this message notifying so. The TWS only allows one request at a time. API client has been unsubscribed from account data. The port number in the TWS/IBG settings has been changed during an active API connection. TWS socket port has been reset and this connection is being dropped. Your market data requests have been recovered and there is no need for you to re-submit them. The TWS/IB Gateway has successfully reconnected to IB's servers. Your market data requests have been lost and need to be re-submitted.Ĭonnectivity between IB and TWS has been restored- data maintained.

CodeĬonnectivity between IB and the TWS has been lost. It is not recommended to operate during the scheduled reset times. Existing orders (native types) will operate normally although execution reports and simulated orders will be delayed until the reset is complete. Important: during a reset period, there may be an interruption in the ability to log in or manage orders. Note that after the system reset, the TWS/IB Gateway will automatically reconnect to our servers and you can resume your operations normally. You are very likely to loose connectivity to our servers at least once a day due to our daily server maintenance downtime as clearly detailed in our Current System Status page. Your client application must pay special attention to them and handle the situation accordingly. They are notifications about the connectivity status between the TWS and itself and our servers. The messages in the table below are not a consequence of any action performed by the client application. It is your responsibility to provide reliable connectivity between the TWS and your client application. Remember that the TWS API simply connects to a running TWS/IB Gateway which most of times will be running on your local network if not in the same host as the client application. All messages delivered by the TWS are usually accompanied by a brief but meaningful description pointing in the direction of the problem. Below is a table with all the messages which can be sent by the TWS/IB Gateway. This is done mostly for simplicity's sake. The TWS uses the method not only to deliver errors but also warnings or informative messages.
