Mcoin

This is a side-project for me to monitor BTC/ETH. The target is to create a helpful command line tool that can run as a cronjob to import data to InfluxDB and do some analytics.

Installation

Add this line to your application's Gemfile:

gem 'mcoin'

And then execute:

$ bundle

Or install it yourself as:

$ gem install mcoin

Usage

Ticker

Add -m to specify market name

mcoin ticker -m Bitfinex
mcoin ticker -m Bitfinex -m Kraken # Multiple

If you want to save it into InfluxDB, add database information.

mcoin ticker -m Bitfinex -d monitor -e http://localhost:8086

To get more information please use -h option.

Subscriber

If you want to subscribe market in your project, you can use Subscriber

require 'mcoin'

# Leave blank to subscribe all available market
subscriber = Mcoin::Subscriber.new(['ETH-USD', 'BTC-USD'], [:Bitfinex])
subscriber.start do |ticker|
  # Deal with Mcoin::Data::Ticker object
end

Please note, the ticker pulls data asynchronously from the market, so the timestamp may not be totally same when you receive it.

Roadmap

• Fetch ticker
  • Fetch in parallels
  • Fetch from multiple market
  • Fetch multiple coin type via specify pair
• Support more public API command
• Improve printer
• Generalize database save interface

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
