Requesting
The IBApi.EClient.reqAccountUpdates function creates a subscription to the TWS through which account and portfolio information is delivered. This information is the exact same as the one displayed within the TWS' Account Window. Note this function receives a specific account along with a flag indicating whether to start or stop the subscription. In a single account structure, the account number is not necessary. Just as with the TWS' Account Window, unless there is a position change this information is updated at a fixed interval of three minutes.

Cancelling
Once the subscription to account updates is no longer needed, it can be cancelled by invoking the IBApi.EClient.reqAccountUpdates method while specifying the susbcription flag to be False:
-
client.reqAccountUpdates(false, "U150462");
-
client.reqAccountUpdates(false, "U150462");
-
client.reqAccountUpdates(False, "U150462")
-
m_pClient->reqAccountUpdates(false, "U150462");
-
1 self.reqAccountUpdates(
False, self.account)
Note: An important key passed back in IBApi.EWrapper.updateAccountValue after a call to IBApi.EClient.reqAccountUpdates is a boolean value 'accountReady'. If an accountReady value of false is returned that means that the IB server is in the process of resetting at that moment, i.e. the account is 'not ready'. When this occurs subsequent key values returned to IBApi::EWrapper::updateAccountValue in the current update can be out of date or incorrect.
Important: only one account at a time can be subscribed at a time. Attempting a second subscription without previously cancelling an active one will not yield any error message although it will override the already subscribed account with the new one. With Financial Advisory (FA) account structures there is an alternative way of specifying the account code such that information is returned for 'All' sub accounts- this is done by appending the letter 'A' to the end of the account number, i.e. reqAccountUpdates(true, "F123456A")
Identifying the Account Keys
Account values delivered via IBApi.EWrapper.updateAccountValue can be classified in the following way:
- Commodities: suffixed by a "-C"
- Securities: suffixed by a "-S"
- Totals: no suffix
For further information, please refer to the Account Window.
Account Value Update Subscriptions by Model
The IBApi.EClient.reqAccountUpdatesMulti can be used in any account structure to create simultaneous account value subscriptions from one or multiple accounts and/or models. As with IBApi.EClient.reqAccountUpdates the data returned will match that displayed within the TWS Account Window.
-
client.reqAccountUpdatesMulti(9002, "U150462", "EUstocks", true);
-
client.reqAccountUpdatesMulti(9002, "U150462", "EUstocks", true);
-
client.reqAccountUpdatesMulti(9002, "U150462", "EUstocks", True)
-
m_pClient->reqAccountUpdatesMulti(9002, "U150462", "EUstocks", true);
-
1 self.reqAccountUpdatesMulti(9005, self.account,
"",
True)
The resulting account and portfolio information will be delivered via the IBApi.EWrapper.accountUpdateMulti and IBApi.EWrapper.accountUpdateMultiEnd
