A Portfolio Model allows individual traders to create a portfolio of financial instruments that they can invest in using a single investment. Instead of setting up individual trades for each instrument, you invest in a model comprising a group of instruments, and the system buys shares for all instruments based on the rules of the model.
For example, you may want to create an investment model containing 10 high-dividend paying tech stocks. Imagine you set the Target Allocations to 10% for each stock in the model. Now, you invest $2000. Using your defined allocations, the system will purchase $200 of each stock (which is 10% of your investment).
