# NowTrade
[![Build Status](https://travis-ci.org/edouardpoitras/NowTrade.svg?branch=master)](https://travis-ci.org/edouardpoitras/NowTrade)
[![Coverage Status](https://coveralls.io/repos/edouardpoitras/NowTrade/badge.svg?branch=master&service=github)](https://coveralls.io/github/edouardpoitras/NowTrade?branch=master)NowTrade is an algorithmic trading library with a focus on creating powerful strategies using easily-readable and simple Python code.
With the help of NowTrade, full blown stock/currency trading strategies, harnessing the power of machine learning, can be implemented with few lines of code.NowTrade strategies are not event driven like most other algorithmic trading libraries available.
The strategies are implemented in a sequential manner (one line at a time) without worrying about events, callbacks, or object overloading.### The Basics
All strategies follow this basic pattern:
* Load the required data for your strategy
* Train your machine learning algorithm (optional)
* Add your technical indicators (example: moving average, relative strength index, neural network, random forest, etc)
* Add criteria based on your technical indicators (example: neural network prediction is higher than current price)
* Associate actions to those criteria (example: go long when a certain criteria is true)
* Create a trading profile (includes information such as your capital, trading amount rules, trading fee rules, slippage rules, etc)
* Send all of this information to a strategy simulator and wait for resultsCheck out some example strategies in the [examples](examples) directory.
### Features
Here is a list of reasons you may want to use NowTrade over alternatives:* Implement strategies easily
* Flexible data connections (store data locally from any remote data connection)
* Easily implement machine learning into strategies (neural networks, random forest, etc)
* Simple, small, and clean code base (build failure on pylint warning)### Cons
List of reasons you may not want to choose NowTrade over alternatives:* Not mature yet
* Performance sacrificed for simple abstraction and code base
* Still lacking many features (contributions welcome!)### Installation
NowTrade has only been tested on Ubuntu 14.04 and 16.04. It will most likely run just fine on any UNIX-based operating system provided all dependencies have been met.
##### Dependencies
apt-get install python-pip python-numpy python-pandas python-scipy cython
pip install pandas-datareader##### TaLib for Technical Indicators
wget -O ta-lib-0.4.0-src.tar.gz http://sourceforge.net/projects/ta-lib/files/ta-lib/0.4.0/ta-lib-0.4.0-src.tar.gz/download
tar xvzf ta-lib-0.4.0-src.tar.gz
cd ta-lib/
./configure --prefix=/usr
make
make install
pip install Ta-Lib##### Matplotlib for pretty charts
apt-get install python-matplotlib
##### For MySQL Support
apt-get install python-mysqldb
##### For MongoDB Local Storage Support
apt-get install mongodb python-pymongo
Note: You may need to un-comment the line '#port 27017' in /etc/mongodb.conf for NowTrade to communicate with mongo
##### For ensemble (random forest) support
apt-get install python-sklearn
##### For neural network support
pip install pybrain
##### Finally, install nowtrade
python setup.py install##### Tests
To run the tests you'll need nose:apt-get install python-nose
Then you can run the tests by running the following command in the root of the repository:
sh tests/test_all.sh
### Give it a Spin
You can try out some strategies in the [examples](examples) directory.
I recommend taking a look at the following examples:
* [Learn how to pull from remote data sources and storing stock data locally for backtesting purposes](examples/data_connection.md)
* [A simple moving average crossover strategy](examples/crossover.md)
* [A simple strategy utilizing the random forest machine learning technique](examples/random_forest.md)
* [A simple strategy utilizing the neural network machine learning technique](examples/neural_network.md)
* [Display some pretty charts of your strategies](examples/figures.md)## See Also
