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 EClient.reqPositionsMulti can be used.

To request model account updates, there is the function EClient.reqAccountUpdatesMulti.

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

modelOrder = Order()
modelOrder.account = "DF12345"
modelOrder.modelCode = "Technology" # model for tech stocks first created in TWS
self.placeOrder(self.nextOrderId(), contract, modelOrder)
