Requesting
A limitation of the function IBApi.EClient.reqAccountUpdates is that it can only be used with a single account at a time. To create a subscription for position updates from multiple accounts, the function IBApi.EClient.reqPositions is available.
Note: The reqPositions function is not available in Introducing Broker or Financial Advisor master accounts that have very large numbers of subaccounts (> 50) to optimize the performance of TWS/IB Gateway v973+. Instead the function reqPositionsMulti can be used to subscribe to updates from individual subaccounts. Also not available with IBroker accounts configured for on-demand account lookup.
After initially invoking reqPositions, information about all positions in all associated accounts will be returned, followed by the IBApi::EWrapper::positionEnd callback. Thereafter, when a position has changed an update will be returned to the IBApi::EWrapper::position function. To cancel a reqPositions subscription, invoke IBApi::EClient::cancelPositions.

-
m_pClient->reqPositions();

Receiving
After invoking the above, the positions will then be received through the IBApi.EWrapper.position callback. After the initial callback (only) of all positions, the IBApi.EWrapper.positionEnd function will be triggered.
- For futures, the exchange field will not be populated in the position callback as some futures trade on multiple exchanges

Cancelling
To cancel the reqPosition subscription, invoke IBApi::EClient::cancelPositions:
-
client.cancelPositions();
-
client.cancelPositions();
-
-
m_pClient->cancelPositions();

Position Update Subscription by Model
The function IBApi.EClient.reqPositionsMulti can be used with any account structure to subscribe to positions updates for multiple accounts and/or models. The account and model parameters are optional if there are not multiple accounts or models available. It is more efficient to use this function for a specific subset of accounts than using IBApi.EClient.reqPositions. If using TWS v983+ a profile name can be accepted in place of group in the account parameter. See Unification of Groups and Profiles
-
client.reqPositionsMulti(9003, "DU74649", "EUstocks");
-
client.reqPositionsMulti(9003, "DU74649", "EUstocks");
-
client.reqPositionsMulti(9003, "DU74649", "EUstocks")
-
m_pClient->reqPositionsMulti(9003, "U150462", "EUstocks");
-
1 self.reqPositionsMulti(9006, self.account,
"")
After invoking IBApi.EClient.reqPositionsMulti data will be returned to the IBApi.EWrapper.positionMulti function. After the initial callback of all positions matching the supplied criteria to reqPositionsMulti, the IBApi.EWrapper.positionMultiEnd function will be triggered. Thereafter, there will only be messages sent to positionsMulti when there is a change. To cancel a positionsMulti subscription the function IBApi.EClient.cancelPositionsMulti is invoked with the same request ID used to create the subscription.
