How to use

---

• 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

• More details about the RSI technical implementation
