The document provides a sequence diagram for the use cases of a smart stock business application. It outlines 9 use cases: 1) Request for opening account, 2) Successful login, 3) Sell order, 4) Buy order, 5) Fund withdrawal order, 6) Cancel order, 7) Approve request, 8) Reject request, and 9) Auto logout. For each use case, it identifies the actors and their interactions, such as a client requesting an account, logging in, making orders, and an admin approving or rejecting requests. It details the flow of activities and communications between actors like the client, admin, and system.
