  • 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.

  • Technology and notions:

    PHP, Laravel 4.2, Python, NumPy, JQuery UI, Ajax, Bootstrap, Chart.js, JSON

  • Duration of the project :

    2nd February 2019 - 14th February 2019, in my free time.

  • 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

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 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.
