Description :
The goal of this project was to learn to integrate python into a website and render information from a database in javascript
This project is composed of the following:
A python script that queries an api and extracts and modifies it so as to get the average price of the top 10 items being sold and saves it to a database.
The information in the database can then be used by the php server and create an API that will respond to Ajax requests.
Clientside javascript that will generate a graph and query the server for data via Ajax requests.
I am using the Warframe Market API here since data is easily available, often updated, exploitable and has a manageable amount of items (2478) as opposed to databases containing real life items and prices owned by big corporations.

What I learned from this project:
During this project I learned to use Ajax and how to make it "communicate" with a php server via JSON.
Python stuff like removing NaN values from an array in python using NumPy : a=np.nan_to_num(numlist[0:4])
Gained valuable experience using JQuery UI and JQuery
Discovered Chart.js and managed to apply a graph to represent a dataset
That you need to clean old data before clearing and refilling the graph otherwise you get old data polluting new graphs
Evolution of item prices over time

Stock Market Displaying 40/1827 items, ignoring items with 0% change.. (Refresh the page for different items) Sorted by difference
Possible improvements and further ideas
- Add a button to refresh the graph, to change the colors / fix errors
- Add a button to reset the graph
- Calculate the daily standard variation: here
- Add a graph showing the hourly price variations for all items (averaged) over the course of a day
- Make an application in Dart with Flutter.io to complement this page.
- Add a loading screen to this page since data in the stock market tends to take time to load..
- Apply seasonal adjustment to the data on the day to day basis.
