PYJUQUE (pai-jook) (Py-thon Ju-ju Qu-ant E-ngine)
This project implements the basic functionality required to engage in algorithmic trading. It can be regarded as a starting point for more complex trading bots.
Expand installation details.
Make sure you have pip installed. To install the latest version run:
pip install -U git+https://github.com/tudorelu/pyjuqueTo install an older (stable) version, run:
pip install pyjuqueShould be good to go! Now check out the example section.
Checkout these examples to get started stratght away: strategy 1, strategy 2. Below are the simplest scripts on how to get started with pyjuque (just code, with comments). Read the next section to understand the thinking behind them.

Main()Expand bot explanation.
The idea behind this library is to allow you to implement whatever trading strategy you want, without having to worry about how to connect to the different exchanges via apis, or how to place, cancel and keep track of orders. You simply provide the signals and pyjuque does the rest.
There are a number of settings that you define, like what symbols to trade on, how much money to place per trade and what exchange to use. You also get to set exit settings such as a take profit value and a stop loss value. All these settings get specified in a config dict. Below is a complete example of a config dict:
## Defines the overall configuration of the bot
bot_config = {
# Name of the bot, as stored in the database
'name' : 'my_bot',
# exchange information (fill with your api key and secret)
'exchange' : {
'name' : 'binance', # or 'okex'
'params' : { # any parameter accepted by ccxt can go here
'api_key': 'your_api_key_here',
'secret' : 'your_secret_here',
# 'password' : 'your_password_here' # if using 'okex'
},
},
# starting balance for bot
'starting_balance' : 0.0005,
# symbols to trade on
# !IMPORTANT! all symbols must trade against the same coin
# !! IE: [AAA/BTC, BBB/BTC] OR [AAA/USDT, CCC/USDT]
'symbols' : ['LINK/BTC', 'ETH/BTC'],
# strategy class / function (here we define the entry and exit strategies.)
# this bot places an entry order when 'customEntryFunction' retruns true
'strategy': {
'custom': True,
'entry_function' : customEntryFunction
},
# when the bot receives the buy signal, the order is placed according
# to the settings specified below
'entry_settings' : {
# between 0 and 100, the % of the starting_balance to put in an order
'initial_entry_allocation': 100,
# number between 0 and 100 - 1% means that when we get a buy signal,
# we place buy order 1% below current price. if 0, we place a market
# order immediately upon receiving signal
'signal_distance': 0.3
},
# This bot exits when our filled orders have reached a take_profit % above
# the buy price, or a stop_loss_value % below it
'exit_settings' : {
# take profit value between 0 and infinity, 3% means we place our sell
# orders 3% above the prices that our buy orders filled at
'take_profit' : 3,
# stop loss value in percent - 10% means stop loss at 10% below our
# buy order's filled price
'stop_loss_value': 10
},
}Besides these settings, you need to provide an entry strategy. It can be as simple as a function, or a more complex strategy class. We'll go over the simple example:
# This is our signal function.
# It receives two parameters - the bot_controller,
# which gives us access to the exchange and to the
# database, and the symbol on which the bot is
# currently checking entry signals.
#
# It must return two values, a boolean and a number.
# The boolean is the signal, and the number is the
# latest price of that symbol
#
def customEntryFunction(bot_controller, symbol):
# ... do some stuff here ...
return signal, last_price_of_symbolThe beauty of this is that you can do whatever the heck you want in that custom entry function, because as long as you return a symbol and the latest price, pyjuque will be happy. You can check coins prices and their indicators, the volume on multiple exchanges, different order books, even weather data, twitter feeds or astronomical events.
Here's a complete example of how to get started with pyjuque:
from pyjuque.Bot import defineBot
## This is our signal function for now.
def customEntryFunction(bot_controller, symbol):
# ... do some stuff here ...
return signal, last_price
## Defines the overall configuration of the bot
bot_config = { ... }
## Runs the bot in an infinite loop, stoppable
## from the terminal with CTRL + C
def Main():
bot_controller = defineBot(bot_config)
while True:
try:
bot_controller.executeBot()
except KeyboardInterrupt:
return
time.sleep(60)
if __name__ == '__main__':
Main()Upon creating the bot, a database will be created in your computer, keeping track of orders placed. You can run this example and it will work - but you should update customEntryFunction to do some calculations & return true sometimes, because in its current state the bot won't ever make any trades.
Checkout these examples for more info: strategy 1, strategy 2.

This library implements the following modules:
At pyjuque/Engine/BotController.py.
A module which handles the buying and selling of assets, given simple or more advanced rules, allowing us to run a strategy indefinitely.
Through the bot controller you can access the following objects
- bot_controller.exchange
- bot_controller.exchange has some methods that are used under the hood by pyjquue, like
- getOHLCV
- placeLimitOrder
- placeMarketOrder
- etc
- bot_controller.exchange has some methods that are used under the hood by pyjquue, like
- bot_controller.exchange.ccxt, a ccxt object which uses the credentials you provided in the bot_config
- bot_controller.session, SQLAlchemy session through which you can query the database
- bot_controller.bot model, the model of the bot as stored in the db
- bot_controller.status_printer, a yaspin spinner used for logging
You can also access the following functions
- bot_controller.executeBot(), which goes through a bot loop of:
- checking signals on symbols and placing orders if signals are true
- checking all open orders placed by the bot and updating them, like so:
- if a buy order was filled it places the subsequent exit order, at a take_profit price above the buy price
- if the current price is below stop_loss_value for an open buy order, exits using market price
- bot_controller.log() which allows you to print some stuff to the terminal
- bot_controller.bot_model.getOrders(bot_controller.session) which allows you to get all orders
- bot_controller.bot_model.getOpenOrders(bot_controller.session) which allows you to get all open orders
Implementing multiple exchanges with ccxt. Check out implementation at CcxtExchange. Currently implemented:
binance okex
Older (Deprecated):
At pyjuque/Exchanges.
At pyjuque/Exchanges/BinanceOrderBook.py.
Creates and stores a local order book for the specified symbols. Order Book is updated every second through a websocket connection to the Exchange (currently Binance). Checkout this example.
from pyjuque.Exchanges.BinanceOrderBook import OrderBook
# Initialize & start OrderBook with desired symbols
ob = OrderBook(symbols=['BTC/USDT', 'LTC/USDT'])
ob.startOrderBook()
...
# Get Updated Order Book data at any point in your code
ordb = ob.getOrderBook()
print(ordb)
