Example implementation of daily buys (Dollar Cost Averaging) with BTCMarkets API written in Node.JS

BTCMarkets DCA

This repository is an example showing how to implement Dollar-Cost Averaging (DCA) using the BTCMarkets API in Node.js.

The strategy here is to purchase a number of cryptocurrencies at the same time every day regardless of the price.

Disclaimer

I'm not a financial advisor. This is not financial advice. Never invest more than you're willing to lose. This code is provided as an example only and may contain bugs. Make sure you understand how it works before running it yourself.

Getting Started

1. Run npm install to ensure dependencies are installed.

2. Get your API keys for BTCMarkets and add them to keys.json. DO NOT PUBLISH YOUR KEYS ANYWHERE.

3. Update the variables in the customisation section to match your investment strategy. It's best to test this with a very small DAILY_SPEND first.

4. Run with node buy.js. To keep the script running indefinitely you can use something like Forever.

Customisation

There are a few variables that you may want to customise in order to tailor this to your own portfolio and investment strategy:

FIAT_CURR - The currency you want to buy in, I'm using AUD, you might want to use something else. Must be supported by BTCMarkets

DAILY_SPEND - The total amount that you want to spend each day, in FIAT_CURR

TOKEN_PERCENT - Contains the coin ticker you want to purchase and the amount (as a percentage) of your daily spend you want to assign to it. Always ensure this adds to 100%. Remove rows if you don't want to purchase them.

You can also customise the schedule.scheduleJob method call to change how often buys are made.
