• Node.js
• Your own domain name
• Mailgun account
• (Optional) a GNU/Linux VPS

We need Maingun to notify you when target prices are available. Mailgun needs a personal domain name to set a custom mail address.

To run the bot periodically, deploy it at a remote GNU/Linux VPS, invoking it as a cron job.

$ git clone https://github.com/cwchentw/twse-price-notify.git
$ cd twse-price-notify
$ npm install
$ npm run prod
$ npm install -g

Then, twse-price-notify should be available in your console environment.

Write a .env for environment variables used in this app:

MAILGUN_DOMAIN=example.com
MAILGUN_KEY=enter-mailgun-api-key-here
[email protected]

Write your target prices of stocks or ETFs in a config file. Let's say it is assets.json:

{
    "0050": [75.0, 80.0],
    "0056": [25.0, 27.0]
}

Run this app:

$ twse-price-notify /path/to/assets.json

To invoke the notification bot periodically, write a cron job like this:

5 9-13 * * 1-5 user twse-price-notify assets.json
