Delphi XE7 web scraping class for use with trading website

I need a Delphi XE7 code (a class) that is capable of retrieving the historical trading history from the user's account on this binary options broker: [login to view URL] Basically, the class must replicate the web pages functionality of reading the trade history online. Must handle login, data ranges, data types internally and store in memory (example using something like a TObjectList) so that the data can be used to populate a VCL form, a data grid or anything other form of output. I don't need a full application, just the class/unit code (please use elegant coherant coding style and comments in english) and a small working sample project. Third-party Internet connection components can be used. The broker allows for "demo account" so you can easily create a test account and make a few trades for testing purposes of the code. max budget: $100
