QTPyLib (**Q**\ uantitative **T**\ rading **Py**\ thon **Lib**\ rary)
is a simple, event-driven algorithmic trading system written in Python 3,
that supports backtesting and live trading using
`Interactive Brokers <https://www.interactivebrokers.com>`_
for market data and order execution.

I originally developed QTPyLib because I wanted for a simple
(but powerful) trading library that will let me to focus on the
trading logic itself and ignore everything else.

`Changelog » <./CHANGELOG.rst>`_

Features
========

- A continuously-running Blotter that lets you capture market data even when your algos aren't running.
- Tick, Bar and Trade data is stored in MySQL for later analisys and backtesting.
- Using pub/sub architecture using `ØMQ <http://zeromq.org>`_ (ZeroMQ) for communicating between the Algo and the Blotter allows for a single Blotter/multiple Algos running on the same machine.
- Includes many common indicators that you can seamlessly use in your algorithm.
- **Support for Order Book, Quote, Time, Tick or Volume based strategy resolutions**
- Have orders delivered to your mobile via SMS (requires a `Nexmo <https://www.nexmo.com/>`_ or `Twilio <https://www.twilio.com/>`_ account)
- Full integration with `TA-Lib <http://ta-lib.org>`_ via dedicated module (`see documentation <http://qtpylib.io/docs/latest/indicators.html#ta-lib-integration>`_)
- Ability to import any Python library (such as `scikit-learn <http://scikit-learn.org>`_ or `TensorFlow <https://www.tensorflow.org>`_) to use them in your algorithms.

-----

Quickstart
==========

There are 5 main components to QTPyLib:

1. ``Blotter`` - handles market data retreival and processing.
2. ``Broker`` - sends and proccess orders/positions (abstracted layer).
3. ``Algo`` - (sub-class of ``Broker``) communicates with the ``Blotter`` to pass market data to your strategies, and proccess/positions orders via ``Broker``.
4. ``Reports`` - provides real time monitoring of trades and open opsitions via Web App, as well as a simple REST API for trades, open positions and market data.
5. Lastly, **Your Strategies**, which are sub-classes of ``Algo``, handle the trading logic/rules. This is where you'll write most of your code.


1. Get Market Data
------------------

To get started, you need to first create a Blotter script:

.. code:: python

# blotter.py
from qtpylib.blotter import Blotter

class MainBlotter(Blotter):
pass # we just need the name

if __name__ == "__main__":
blotter = MainBlotter()
blotter.run()

Then, with IB TWS/GW running, run the Blotter from the command line:

.. code:: bash

$ python blotter.py

If your strategy needs order book / market depth data, add the ``--orderbook`` flag to the command:

.. code:: bash

$ python blotter.py --orderbook


2. Write your Algorithm
-----------------------

While the Blotter running in the background, write and execute your algorithm:

.. code:: python

# strategy.py
from qtpylib.algo import Algo

class CrossOver(Algo):

def on_start(self):
pass

def on_fill(self, instrument, order):
pass

def on_quote(self, instrument):
pass

def on_orderbook(self, instrument):
pass

def on_tick(self, instrument):
pass

def on_bar(self, instrument):
# get instrument history
bars = instrument.get_bars(window=100)

# or get all instruments history
# bars = self.bars[-20:]

# skip first 20 days to get full windows
if len(bars) < 20:
return

# compute averages using internal rolling_mean
bars['short_ma'] = bars['close'].rolling_mean(window=10)
bars['long_ma'] = bars['close'].rolling_mean(window=20)

# get current position data
positions = instrument.get_positions()

# trading logic - entry signal
if bars['short_ma'].crossed_above(bars['long_ma'])[-1]:
if not instrument.pending_orders and positions["position"] == 0:

# buy one contract
instrument.buy(1)

# record values for later analysis
self.record(ma_cross=1)

# trading logic - exit signal
elif bars['short_ma'].crossed_below(bars['long_ma'])[-1]:
if positions["position"] != 0:

# exit / flatten position
instrument.exit()

# record values for later analysis
self.record(ma_cross=-1)


if __name__ == "__main__":
strategy = CrossOver(
instruments = [ ("ES", "FUT", "GLOBEX", "USD", 201609, 0.0, "") ], # ib tuples
resolution = "1T", # Pandas resolution (use "K" for tick bars)
tick_window = 20, # no. of ticks to keep
bar_window = 5, # no. of bars to keep
preload = "1D", # preload 1 day history when starting
timezone = "US/Central" # convert all ticks/bars to this timezone
)
strategy.run()


To run your algo in a **live** enviroment, from the command line, type:

.. code:: bash

$ python strategy.py --logpath ~/qtpy/


The resulting trades be saved in ``~/qtpy/STRATEGY_YYYYMMDD.csv`` for later analysis.


3. Viewing Live Trades
----------------------

While the Blotter running in the background, write the dashboard:

.. code:: python

# dashboard.py
from qtpylib.reports import Reports

class Dahboard(Reports):
pass # we just need the name

if __name__ == "__main__":
dashboard = Dahboard(port = 5000)
dashboard.run()


To run your dashboard, run it from the command line:

.. code:: bash

$ python dashboard.py

>>> Dashboard password is: a0f36d95a9
>>> Running on http://0.0.0.0:5000/ (Press CTRL+C to quit)

Now, point your browser to http://localhost:5000 and use the password generated to access your dashboard.
