FinnHub stocks analysis

This project is implemented as a part of a homework exercise for [077] - Real Time Embedded Systems course of ECE Department, AUTh.

This fetches stock information changes as they happen in real time, using websockets, runs some analysis and persists the information as it becomes available. It should consume the least cpu it can as it should be able to be deployed in a microcontroller.

Getting Started

Prerequisites

1. Rust

To install them on variant Linux distributions follow the instructions below

Fedora

$ sudo dnf upgrade --refresh # updates installed packages and repositories metadata
$ sudo dnf install rust openssl-devel # or use rustup https://www.rust-lang.org/tools/install

Ubuntu

$ sudo apt-get update && sudo apt-get upgrade # updates installed packages and repositories metadata
$ sudo apt-get install rust libssl-dev # or use rustup https://www.rust-lang.org/tools/install 

Build & Run

First, go to finnhub.io and get a free API Key. Save it for later use.

Then to build the application:

1. Compile the project

   $ cargo build --release # if you want a development build just drop the release flag.  

   To cross-compile for Raspberry Pi, you gotta install the toolchain via rustup as most package managers will only ship you the toolchain for your machine's architecture.

   $ cargo build --release --target=aarch64-unknown-linux-gnu 

   If you are compiling on the RP, just run the first command. Rust compiler should pick your architecture automatically.
2. Run the binary

   $ ./target/release/finnhub_ws  --token <your-finnhub-token> --stocks <stockSymbol> --stocks <stockSymbol>
