BuyLow Ren

Be free of the pain of watching stock prices change. Get stock updates straight to your email - but only ones that help you know when to buy low.

Features

• Easily Customizable
  • Choose stocks you want to follow
  • Set a minimum percentage drop that you want to be notified about
  • Set a percentage of the 52 Week High that you don't want to be over
• Get an email each time a stock price meets your filters AND reaches a new low for the day
• Deploy and schedule (every 5 minutes 9 am - 5 pm, M-F) with one command, for free
• Test it out locally without deploying

How it Works

• Uses the IEX API for stock price data
• Uses Webtask to deploy and schedule Buylow Ren
• Uses Mailgun to send you an email

Prerequisites

• Installed nvm or node.js v8.10+
• Get a free Webtask account.
• Get a free Mailgun account. You don't need to verify a domain. Just get a domain and add yourself as an email receiver.

Run It

Installation

$ git clone git@github.com:jdd1260/buylow-ren.git
$ cd buylow-ren
$ nvm install && npm install
$ cp .env-example .env

Then, open .env and replace the values that you would like to use - including your Mailgun API key and domain, stocks you want to follow, cutoffs for daily change and 52 week high, and your email address.

Run locally

$ npm start

Deploy

$ npm run deploy

As part of the deploy process you will need to login using your webtask account. By default it will run every 5 minues, from 9 am - 5 pm (New York) Monday-Friday.

Further Customization

• You can change your run schedule by editing the CRON string in the deploy script in package.json
• You could add, remove, or modify filters in webtask.js in the filterStocks method.
• You could change the structure of the email you received in webtask.js in the makeEmail method.
