Account Updates

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. Just as with the TWS' Account Window, this information is updated every three minutes.

  • client.reqAccountUpdates(true, "U150462");
  • client.reqAccountUpdates(true, "U150462");
  • client.reqAccountUpdates(True, "U150462")
  • m_pClient->reqAccountUpdates(true, "U150462");
  • 1  self.reqAccountUpdates(True, self.account)

Receiving

Resulting account and portfolio information will be delivered via the IBApi.EWrapper.updateAccountValue, IBApi.EWrapper.updatePortfolio, IBApi.EWrapper.updateAccountTime and IBApi.EWrapper.accountDownloadEnd

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 When this occurs subsequent key values returned to IBApi::EWrapper::updateAccountValue in the current update can be out of date or incorrect.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.

Models

The IBApi.EClient.reqAccountUpdatesMulti can be used with multiple account structures to subscribe to updates in real time for multiple accounts and/or models. As with IBApi.EClient.reqAccountUpdates 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.

  • client.reqAccountUpdatesMulti(9002, "U150462", "EUstocks", true);
  • client.reqAccountUpdatesMulti(9002, "U150462", "EUstocks", true);
  • client.reqAccountUpdatesMulti(9002, "U150462", "EUstocks", True)
  • m_pClient->reqAccountUpdatessMulti(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
