Coinbase Recurring Buys

This script allows you to automatically purchase or sell cryptocurrencies on Coinbase using market or limit orders. The script can be scheduled to run at regular intervals using a cronjob.

Prerequisites

• A Coinbase account with API access enabled
• Node.js and npm installed on your Ubuntu machine
• Your Coinbase API key and secret

Setup

1. Clone the Repository

   Clone this repository to your local machine:

   git clone https://github.com/BriungRi/coinbase-recurring-buys.git
   cd coinbase-recurring-buys

2. Install Dependencies

   Install the required npm packages:

   pnpm install

3. Configure API Credentials

   Copy the .env.example file to .env and fill in your Coinbase API credentials:

   API_KEY=
   API_SECRET=

4. Test the Script

   Run the script manually to ensure it works:

   For a market order (e.g., buy $1 of BTC-USD):

   pnpm start market --amount 1 --product BTC-USD --side BUY

   For a limit order (e.g., buy $1 of BTC-USD 1% below the best bid):

   pnpm start limit --amount 1 --product BTC-USD --side BUY --percent 1

   To test in the sandbox environment, add the --dry flag:

   pnpm start market --amount 1 --product BTC-USD --side BUY --dry

Setting Up the Cronjob

1. Open the Crontab Editor

   Open the crontab editor:

   crontab -e

2. Schedule the Script

   Add the following line to schedule the script to run every day at 2 AM:

   0 2 * * * cd /path/to/your/repo && pnpm start market --amount 1 --product BTC-USD --side BUY

   Replace /path/to/your/repo with the actual path to your repository. You can get this by running pwd in your repository directory.

   We recommend using crontab.guru to check and generate cron schedules.

3. Save and Exit

   Save the file and exit the editor. The cronjob is now set up to run the script at the specified time.

4. Check Previous Runs

   To check the status of previous runs, view the cron logs:

   grep CRON /var/log/syslog

   You can also check your Coinbase account history to verify successful transactions.

Notes

• Ensure your account has sufficient funds to cover the purchases
• Consider setting up recurring USDC buys as they typically don't incur fees
• Monitor your Coinbase account regularly to verify successful transactions
