In no way am I a financial advisor or an expert in this field. I would only recommend trying out with small amounts you are willing to lose for educational purposes. Along with this, much of crypto is still a wild wild west, which no person or bot can predict.

Setup

For our trading bot we’ll be using Zenbot which describes itself as a “command-line cryptocurrency trading bot using Node.js and MongoDB”. You can view the project’s Github here. This guide assumes a fresh installation of Ubuntu 16.04, but many of these commands can be easily modified to work on other OS’s.

Requirements

NodeJS

# This installs the latest version of NodeJS 8 (8.x) $ curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash - $ sudo apt-get install -y nodejs

MongoDB

# Import the public key used by the package management system. $ sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 2930ADAE8CAF5059EE73BB4B58712A2291FA4AD5 # Create a list file for Mongo $ echo "deb [ arch=amd64,arm64 ] https://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.6 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.6.list # Update the package list $ sudo apt-get update # Install the latest version of Mongo $ sudo apt-get install -y mongodb-org # Start Mongo $ sudo service mongod start # To Stop: sudo service mongod stop # To Restart: sudo service mongod restart

Installing Zenbot

Now we’ll clone, and setup the latest version of Zenbot as per it’s Github Repo.

# Clone the repo $ git clone https://github.com/DeviaVir/zenbot # Enter in the folder and copy over the configuration file if needed $ cd zenbot $ cp conf-sample.js conf.js

Now you’ll have to edit the config to fit your use case. You can use nano by running nano conf.js or you can use any other tool. Possible customization options:

Notifications Pushbullet Slack IFTT XMPP Discord Prowl TextBelt

Exchanges GDAX Poloniex Kraken Bittrex Binance Quadriga Gemini Bitfinex CEX.IO Bitstamp

Currency Pairs ( $ zenbot list-selectors )

Trading Strategies ( $ zenbot list-strategies ) bollinger - Buy when (Signal ≤ Lower Bollinger Band) and sell when (Signal ≥ Upper Bollinger Band). cci_srsi - Stochastic CCI Strategy crossover_vwap - Estimate trends by comparing “Volume Weighted Average Price” to the “Exponential Moving Average”. dema - Buy when (short ema > long ema) and sell when (short ema < long ema). forex_analytics - Apply the trained forex analytics model. macd - Buy when (MACD - Signal > 0) and sell when (MACD - Signal < 0). neural - Use neural learning to predict future price. Buy = mean(last 3 real prices) < mean(current & last prediction) noop - Just do nothing. Can be used to e.g. generate candlesticks for training the genetic forex strategy. rsi - Attempts to buy low and sell high by tracking RSI high-water readings. sar - Parabolic SAR speed - Trade when % change from last two 1m periods is higher than average. srsi_macd - Stochastic MACD Strategy stddev - Buy when standard deviation and mean increase, sell on mean decrease. ta_ema - Buy when (EMA - last(EMA) > 0) and sell when (EMA - last(EMA) < 0). Optional buy on low RSI. ta_macd - Buy when (MACD - Signal > 0) and sell when (MACD - Signal < 0). trend_ema (default) - Buy when (EMA - last(EMA) > 0) and sell when (EMA - last(EMA) < 0). Optional buy on low RSI. trendline - Calculate a trendline and trade when trend is positive vs negative. trust_distrust - Sell when price higher than $sell_min% and highest point - $sell_threshold% is reached. Buy when lowest price point + $buy_threshold% reached.

Running Zenbot with paper trading.

# Install NPM dependencies $ npm install # Start paper trading $ ./zenbot.sh trade --paper # If customized: $ ./zenbot.sh trade --paper --conf ./conf.js

It will now download previous data in order to train the strategy set for the bot. This may take awhile.

When it’s done you’ll see something like this: This chart shows the latest prices of the selector we chose (ex. BTC-USD), along with recent actions the bot has taken.

Manual Trading

Awesome! We now have a fully functional simulated crypto currency trading bot. If needed you can override the bot and manually set limit buy or sell orders by pressing the keys B or S respectively. You can cancel these orders if you change your mind by pressing C .
