💵 Stock-Overflow 💶

🔎 Overview

Stock-Overflow is a stock recommendation system tailored for the Taiwanese stock market. It leverages various strategies and indicators to identify potentially lucrative stock investment opportunities. The system provides recommendations based on fundamental analysis, technical analysis, and chip analysis. Additionally, it utilizes web scraping to fetch real-time stock market data and sends recommendations to users via the LINE messaging platform.

📌 Features

• Highly Customizable Filtering Criteria: Tailor screening conditions to match specific investment preferences, allowing users to define criteria that align with their unique strategies.

• Convenient Daily Push Notifications via LINE: Enjoy the convenience of receiving daily stock recommendations directly through LINE messaging, ensuring users stay informed without the need for manual checks.

🪄 Deployment Tools

• Web Service: Render
• Scheduler: Cron-job
• LINE Chatbot: LINE Developers

🔖 How to Deploy the Service

1. Modify the render.yaml file in your repository. (You can also find the template here.)

   • Modify the value of name, repo, and maybe some values of envVars.

2. Go to Render's blueprint, create a new instance with the target repository and the render.yaml file.

   • The environment variables CHANNEL_ACCESS_TOKEN and CHANNEL_SECRET can be found from LINE Developers.
   • The environment variable API_ACCESS_TOKEN should be designated with a unique value to enhance the security.
   • The environment variable TZ should be configured to Asia/Taipei.

3. Upon creating and running the instance, you will receive a service URL for this web service from the dashboard (e.g., https://stock-overflow-api.onrender.com).

4. Append /callback to the service URL to construct the webhook URL. Paste this webhook URL into the LINE Webhook URL section on LINE Developers.

5. Configure the scheduler (e.g., Cron-job) to invoke the /wakeup API endpoint at designated times daily, ensuring users receive notifications.
