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.

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.
