Python-based framework for backtesting trading strategies & analyzing financial markets [GUI :neckbeard:]

Quantdom

Quantdom is a simple but powerful backtesting framework written in python, that strives to let you focus on modeling financial strategies, portfolio management, and analyzing backtests. It has been created as a useful and flexible tool to save the systematic trading community from re-inventing the wheel and let them evaluate their trading ideas easier with minimal effort. It's designed for people who are already comfortable with Python and who want to create, test and explore their own trading strategies.

Quantdom is in an early alpha state at the moment. So please be patient with possible errors and report them.

Features

• Free, open-source and cross-platform backtesting framework
• Multiple data feeds: csv files and online sources such as Google Finance, Yahoo Finance, Quandl and more
• Investment Analysis (performance and risk analysis of financial portfolio)
• Charting and reporting that help visualize backtest results

Requirements

• Python 3.6 or higher
• PyQt5
• PyQtGraph
• NumPy
• See pyproject.toml for full details.

Installation

Using the binaries

You can download binary packages for your system (see the Github Releases page for available downloads):

• For Windows
• For MacOS
• For Linux

Running from source code

You can install last stable release from pypi:

$ pip install quantdom

And latest development version can be installed directly from GitHub:

$ pip install -U git+https://github.com/constverum/Quantdom.git

After that, to run the application just execute one command:

$ quantdom

Usage

1. Run Quantdom.
2. Choose a market instrument (symbol) for backtesting on the Data tab.
3. Specify a file with your strategies on the Quotes tab, and select one of them.
4. Run a backtest. Once this is done, you can analyze the results and optimize parameters of the strategy.

Strategy Examples

Three-bar strategy

A simple trading strategy based on the assumption that after three consecutive bullish bars (bar closing occurred higher than its opening) bulls predominate in the market and therefore the price will continue to grow; after 3 consecutive bearish bars (the bar closes lower than its opening), the price will continue to down, since bears predominate in the market.

from quantdom import AbstractStrategy, Order, Portfolio

class ThreeBarStrategy(AbstractStrategy):

    def init(self, high_bars=3, low_bars=3):
        Portfolio.initial_balance = 100000  # default value
        self.seq_low_bars = 0
        self.seq_high_bars = 0
        self.signal = None
        self.last_position = None
        self.volume = 100  # shares
        self.high_bars = high_bars
        self.low_bars = low_bars

    def handle(self, quote):
        if self.signal:
            props = {
                'symbol': self.symbol,  # current selected symbol
                'otype': self.signal,
                'price': quote.open,
                'volume': self.volume,
                'time': quote.time,
            }
            if not self.last_position:
                self.last_position = Order.open(**props)
            elif self.last_position.type != self.signal:
                Order.close(self.last_position, price=quote.open, time=quote.time)
                self.last_position = Order.open(**props)
            self.signal = False
            self.seq_high_bars = self.seq_low_bars = 0

        if quote.close > quote.open:
            self.seq_high_bars += 1
            self.seq_low_bars = 0
        else:
            self.seq_high_bars = 0
            self.seq_low_bars += 1

        if self.seq_high_bars == self.high_bars:
            self.signal = Order.BUY
        elif self.seq_low_bars == self.low_bars:
            self.signal = Order.SELL

Documentation

In progress ;)

TODO

• Add integration with TA-Lib
• Add the ability to use TensorFlow/CatBoost/Scikit-Learn and other ML tools to create incredible algorithms and strategies. Just as one of the first tasks is Elliott Wave Theory(Principle) - to recognize of current wave and on the basis of this predict price movement at confidence intervals
• Add the ability to make a sentiment analysis from different sources (news, tweets, etc)
• Add ability to create custom screens, ranking functions, reports
