There are many ways to make a living. Some try to speculate in the financial markets by looking at charts and numbers, in order to come up with a conclusion, which should lead to financial freedom and more.
This paper should explain a little about historical financial data and its limitations.
The Downloader downloads free financial quotes from public web portals.
It is extracting only the essential data, and is preparing and saving the gained data into a usable file, for further analysis.
Theoretical, we could download all kind of data. Weather, sports, lotto, statistics of all sorts. The problem is, that web portals which provide free data, any kind of data, change, like wind and fashion, from time to time.
This is making a constant download and extracting script for a program difficult or impossible, hence, man and brain power is required from time to time to adapt to the changes.
There are few things a project leader of gaining data can guide and plan. One is that he or she is selecting a web site or source which looks stable and constant for more than just few moments.
This means the programmer, also there might be hundreds of other possibilities and sources available, will limit him or herself to few major web portals, to keep work load to an acceptable level.
