Model Portfolios and the API

Advisors can use Model Portfolios to easily invest some or all of a client's assets into one or multiple custom-created portfolios, rather than tediously managing individual investments in single instruments.

More about Model Portfolios

The TWS API can access model portfolios in accounts where this functionality is available and a specific model has previously been setup in TWS. API functionality allows the client application to request model position update subscriptions, request model account update subscriptions, or place orders to a specific model.

Model Portfolio functionality not available in the TWS API:

  • Portfolio Model Creation
  • Portfolio Model Rebalancing
  • Portfolio Model Position or Cash Transfer

To request position updates from a specific model, the function IBApi::EClient::reqPositionsMulti can be used: Position Update Subscription by Model

To request model account updates, there is the function IBApi::EClient::reqAccountUpdatesMulti, see: Account Value Update Subscriptions by Model

To place an order to a model, the IBApi.Order.ModelCode field must be set accordingly, for example:

  • Order modelOrder = OrderSamples.LimitOrder("BUY", 200, 100);
    modelOrder.Account = "DF12345"; // master FA account number
    modelOrder.ModelCode = "Technology"; // model for tech stocks first created in TWS
    client.placeOrder(nextOrderId++, ContractSamples.USStock(), modelOrder);
  • Order modelOrder = OrderSamples.LimitOrder("BUY", 200, 100);
    modelOrder.account("DF12345"); // master FA account number
    modelOrder.modelCode("Technology"); // model for tech stocks first created in TWS
    client.placeOrder(nextOrderId++, ContractSamples.USStock(), modelOrder);
  • Dim modelOrder As Order = OrderSamples.LimitOrder("BUY", 200, 100)
    modelOrder.Account = "DF12345" 'master FA account number
    modelOrder.ModelCode = "Technology" 'model for tech stocks first created in TWS
    client.placeOrder(increment(nextOrderId), ContractSamples.USStock(), modelOrder)
  • Order modelOrder = OrderSamples::LimitOrder("BUY", 200, 100);
    modelOrder.account = "DF12345";
    modelOrder.modelCode = "Technology";
    m_pClient->placeOrder(m_orderId++, ContractSamples::USStock(), modelOrder);
  • 1  modelOrder = OrderSamples.LimitOrder("BUY", 200, 100)
    2  modelOrder.account = "DF12345"
    3  modelOrder.modelCode = "Technology" # model for tech stocks first created in TWS
    4  self.placeOrder(self.nextOrderId(), ContractSamples.USStock(), modelOrder)
