QuantBlock is a web app inspired by Scratch, built for beginners to play around with algorithmic stock trading strategies without writing any code. The web app also backtests these strategies and outputs the returns. Users can build strategies using simple drag-and-drop elements. Right now, there are 8 indicators and 2 operators, but soon more will be added. The UI is inspired by early 2000s GUIs and the Bloomberg terminal.The front-end is written using the HTML, CSS, and JavaScript stack. The front-end simply converts the user-defined strategy and sends it to a Python backend where all the processing happens. This backend then returns the final portfolio value, the percentage return, and the daily portfolio value in an array so that it can be displayed on a graph.Disclaimer: The demo is not fully functional yet.Future work:-Better Documentation-More indicators and the ability to create custom indicators-Bug Fixes
