- Clone the project and run it on Xcode
** How does it work?**
- A Python microservice pulls data from the Yahoo Finance API, then performs the necessary calculations to create the data indicators: RSI, EMA100, and EMA200.
- The miscroservice then dumps this data into a JSON object, publicly accessible via a web endpoint.
- The SwiftUI app fetches that JSON object from the microservice endpoint and display the data in the app's interface.
Where does the data come from?
-
RSI (Relative Strengh Index), as well as EMA (Exponential Moving Averages) for 100 and 200 sessions are calculated using Python and data analysis modules here
