In point-form, identify the actors involved, identify each node, and describe the logic of the following workflow. For example: 1. There is 1 internal actor "Brokerage", and 1 external actor with multiple instances "Customer". 2. Start-Start message event catches "Order from investor received" from Customer. 3. Intermediate conditional catching event "Stock Price Above $100 " holds token until stock price is above $100. 4. Convergent XOR gateway. Token flows through. 5.
