Layer 2 – Business logic – Users management &
security

StockWatch uses ASP.NET Built-in Users Management
mechanism.

The mechanism generate memberships data tables in the
database.

Built-in User controls offer easy login (Login control) ,
registration (CreateUserWizard) , Password recovery and
Dynamic content according to the user state (LoginView
control).

Roles management – StockWatch uses the roles
mechanism in order to distinguish between Admin user
(management page) and regular user.
Layer 2 – Business logic – News feeds

StockWatch collect news feeds from Yahoo finance , Google
finance & Msn money.

News feeds are dynamic according to the presented stock
or stocks in current portfolio.

News feeds are being displayed using Google feed Ajax
API. (client side).
Layer 2 – Business logic – American Bulls data
parsing

Everyday at 2 am a data parsing process gets data from
American Bulls web pages.

The process has 3 stages :
◦ Page download
◦ Data parsing and saving into data base
◦ Grading process:
 Grade = (Stock hits / Stock predictions)
 The information for the stock grade is based on
predictions results history from American bulls.
Layer 3 – Presentation layer – AJAX
We used Ajax auto complete control for symbol search, this
control use Web Service function. The use of Web Service helps
the System run smoothly, and enhance the system performance.
