Known Issues and current status

Currently (11 days after being released), Zenbot 4 is functional, but is having trouble reliably making profit. At this point, I would recommend against trading with large amounts until some of these issues can be worked out:

Many people are reporting losses in live trading even if the simulation results and/or paper trading is positive.
This is my highest priority right now, since an unprofitable bot is not worth much, but please understand that reliably making profit is hard, and so is making a realistic simulator.
The losses may be due to the default strategy not working well in sideways (non-trending) market conditions, slippage during limit order execution, or both. Currently I would recommend against using Zenbot on a market that is non-trending or trending generally downwards.
The limit-order strategy that Zenbot uses to avoid taker fees, is prone to race conditions and delays. A mode for using market-type orders will probably need to be made, which may make frequent-trade strategies less viable due to fees, but more reliable execution overall.
An upcoming feature will allow Zenbot to use a limited amount of your balance, which will help with experimenting with live trading, but mitigating the possible losses from the issues above.

Zenbot is a hobby project for me and I'm sorry that I can't devote myself full-time to it. Since I'm getting busier, development may slow down a bit from here, so please be patient if issues aren't fixed right away.

Description

Zenbot is a command-line cryptocurrency trading bot using Node.js and MongoDB. It features:

Fully-automated technical-analysis-based trading approach
Full support for GDAX, Poloniex, Kraken and Bittrex, work on further exchange support is ongoing.
Plugin architecture for implementing exchange support, or writing new strategies
Simulator for Backtesting strategies against historical data
"Paper" trading mode, operates on a simulated balance while watching the live market
Configurable sell stops, buy stops, and (trailing) profit stops
Flexible sampling period and trade frequency - averages 1-2 trades/day with 1h period, 15-50/day with 5m period

Disclaimer

Zenbot is NOT a sure-fire profit machine. Use it AT YOUR OWN RISK.
Crypto-currency is still an experiment, and therefore so is Zenbot. Meaning, both may fail at any time.
Running a bot, and trading in general requires careful study of the risks and parameters involved. A wrong setting can cause you a major loss.
Never leave the bot un-monitored for long periods of time. Zenbot doesn't know when to stop, so be prepared to stop it if too much loss occurs.
Often times the default trade parameters will underperform vs. a buy-hold strategy, so run some simulations and find the optimal parameters for your chosen exchange/pair before going "all-in".

Quick-start

1. Requirements: Linux or OSX or Docker, Node.js and MongoDB.

2. Install zenbot 4:

Run in your console,

git clone https://github.com/carlos8f/zenbot.git

Or, without git,

wget https://github.com/carlos8f/zenbot/archive/master.tar.gz
tar -xf zenbot-master.tar.gz
mv zenbot-master zenbot

Create your configuration file by copying conf-sample.js to conf.js:

cp conf-sample.js conf.js

View and edit conf.js.
It's possible to use zenbot in "paper trading" mode without making any changes.
You must add your exchange API keys to enable real trading however.
API keys do NOT need deposit/withdrawl permissions.

If using Docker, skip to section "Docker" below.

Install dependencies:

cd zenbot
npm install
# optional, installs the `zenbot.sh` binary in /usr/local/bin:
npm link

Docker

To run Zenbot under Docker, install Docker, Docker Compose, Docker Machine (if necessary) You can follow instructions at https://docs.docker.com/compose/install/

After installing (step 2 above),

cd zenbot
docker-compose build
docker-compose up (-d if you don't want to see the log)

If you wish to run commands (e.g. backfills, list-selectors), you can run this separate command after a successful docker-compose up -d:

docker run --rm --link zenbot_mongodb_1:mongodb -it zenbot_server ./zenbot.sh list-selectors
docker run --rm --link zenbot_mongodb_1:mongodb -it zenbot_server ./zenbot.sh backfill <selector> --days <days>

Vocab: selectors

A "selector" is a short identifier that tells Zenbot which exchange and currency pair to act on. Use the form {exchange_slug}.{asset}-{currency}. A complete list of selectors your Zenbot install supports can be found with:

zenbot list-selectors

gdax:
  gdax.BTC-EUR   (BTC/EUR)
  gdax.BTC-GBP   (BTC/GBP)
  gdax.BTC-USD   (BTC/USD)
  gdax.ETH-BTC   (ETH/BTC)
  gdax.ETH-USD   (ETH/USD)
  gdax.LTC-BTC   (LTC/BTC)
  gdax.LTC-USD   (LTC/USD)

poloniex:
  poloniex.AMP-BTC   (Synereo AMP/BTC)
  poloniex.ARDR-BTC   (Ardor/BTC)
  poloniex.BCN-BTC   (Bytecoin/BTC)
  poloniex.BCN-XMR   (Bytecoin/XMR)
  poloniex.BCY-BTC   (BitCrystals/BTC)

...etc

3. (optional) Run simulations for your chosen selector

To backfill data (provided that your chosen exchange supports it), use:

zenbot backfill <selector> --days <days>

After you've backfilled, you can run a simulation:

zenbot sim <selector> [options]

For a list of options for the sim command, use:

zenbot sim --help

For additional options related to the strategy, use:

zenbot list-strategies

By default the sim will start with 1000 units of currency. Override with --currency_capital and --asset_capital.
Open sim_result.html in your browser to see a candlestick graph with trades.

Screenshot and example result

Zenbot outputs an HTML graph of each simulation result. In the screenshot below, the pink arrows represent the bot buying (up arrow) and selling (down arrow) as it iterated the historical data of GDAX exchange's BTC/USD product.

end balance 2954.50 (195.45%)
buy hold 1834.44 (83.44%)
vs. buy hold 61.06%
110 trades over 91 days (avg 1.21 trades/day)

Zenbot started with $1,000 USD and ended with $2,954.50 after 90 days, making 195% ROI! In spite of a buy/hold strategy returning a respectable 83.44%, Zenbot has considerable potential for beating buy/holders.

Note that this example used tweaked settings to achieve optimal return: --enable_profit_stop_pct=10, --profit_stop_pct=4, trend_ema=36, and --sell_rate=-0.006. Default parameters yielded around 65% ROI.
Raw data from simulation

4. Run zenbot

The following command will launch the bot, and if you haven't touched c.default_selector in conf.js, will trade the default BTC/USD pair on GDAX.

zenbot trade [--paper]

Use the --paper flag to only perform simulated trades while watching the market.

Here's how to run a different selector (example: ETH-BTC on Poloniex):

./zenbot trade poloniex.eth-btc

For a full list of options for the trade command, use:

zenbot trade --help

  Usage: trade [options] [selector]

  run trading bot against live market data

Conf/argument override files

To run trade or sim commands with a pre-defined set of options, use:

zenbot trade --conf <path>

Where <path> points to a JS file that exports an object hash that overrides any conf or argument variables. For example, this file will run gdax.ETH-USD with options specific for that market:

var c = module.exports = {}

// ETH settings
c.selector = 'gdax.ETH-USD'
c.period = '10m'
c.trend_ema = 20
c.neutral_rate = 0.1
c.oversold_rsi_periods = 20
c.max_slippage_pct = 10
c.order_adjust_time = 10000

About the ema_trend strategy (default)

The default strategy is called trend_ema and resides at ./extensions/strategies/trend_ema.
Defaults to using a 10m period, but you can override this with adding e.g. --period=5m to the sim or trade commands.
Computes the 20-period EMA of the current price, and calculates the percent change from the last period's EMA to get the trend_ema_rate
Considers trend_ema_rate >= 0 an upwards trend and trend_ema_rate < 0 a downwards trend
Filters out low values (whipsaws) by neutral_rate, which when set to auto, uses the standard deviation of the trend_ema_rate as a variable noise filter.
Buys at the beginning of upwards trend, sells at the beginning of downwards trend
If oversold_rsi is set, tries to buy when the RSI dips below that value, and then starts to recover (a counterpart to --profit_stop_enable_pct, which sells when a percent of profit is reached, and then dips)
The bot will always try to avoid trade fees, by using post-only orders and thus being a market "maker" instead of a "taker". Some exchanges will, however, not offer maker discounts.

About the macd strategy

The moving average convergence divergence calculation is a lagging indicator, used to follow trends.

Can be very effective for trading periods of 1h, with a shorter period like 15m it seems too erratic and the Moving Averages are kind of lost.
It's not firing multiple 'buy' or 'sold' signals, only one per trend, which seems to lead to a better quality trading scheme.
Especially when the bot will enter in the middle of a trend, it avoids buying unless it's the beginning of the trend.

Option tweaking tips

Trade frequency is adjusted with a combination of --period and --trend_ema. For example, if you want more frequent trading, try --period=5m or --trend_ema=15 or both. If you get too many ping-pong trades or losses from fees, try increasing period or trend_ema or increasing neutral_rate.
Sometimes it's tempting to tell the bot trade very often. Try to resist this urge, and go for quality over quantity, since each trade comes with a decent amount of slippage and whipsaw risk.
--oversold_rsi=<rsi> will try to buy when the price dives. This is one of the ways to get profit above buy/hold, but setting it too high might result in a loss of the price continues to fall.
In a market with predictable price surges and corrections, --profit_stop_enable_pct=10 will try to sell when the last buy hits 10% profit and then drops to 9% (the drop % is set with --profit_stop_pct). However in strong, long uptrends this option may end up causing a sell too early.
As of v4.0.5, the --neutral_rate=auto filter is disabled, which is currently producing better results with the new default 10m period. Some coins may benefit from --neutral_rate=auto though, try simulating with and without it.

Manual trade tools

Zenbot's order execution engine can also be used for manual trades. Benefits include:

Avoids market-order fees by using a short-term limit order
Can automatically determine order size from account balance
Adjusts order every 30s (if needed) to ensure quick execution
If an order is partially filled, attempts to re-order with remaining size

The command to buy is:

zenbot buy <selector> [--size=<size>] [--pct=<pct>]

For example, to use your remaining USD balance in GDAX to buy Bitcoin:

zenbot buy gdax.BTC-USD

Or to sell 10% of your BTC,

zenbot sell gdax.BTC-USD --pct=10
