Backtrader-IBAPI Fork

This is a public fork of Backtrader, a Python backtesting and trading library, modified to integrate with Interactive Brokers' IBAPI.

Backtrader uses IbPy package for live tading with IBAPI, however that package is no longer supported hence the need to rather use IBKR's official API package.

Yahoo API Note:

[2018-11-16] After some testing it would seem that data downloads can be again relied upon over the web interface (or API v7)

The ticket system is (was, actually) more often than not abused to ask for advice about samples.

Here a snippet of a Simple Moving Average CrossOver. It can be done in several different ways. Use the docs (and examples) Luke! ::

from datetime import datetime import backtrader as bt

class SmaCross(bt.SignalStrategy): def init(self): sma1, sma2 = bt.ind.SMA(period=10), bt.ind.SMA(period=30) crossover = bt.ind.CrossOver(sma1, sma2) self.signal_add(bt.SIGNAL_LONG, crossover)

cerebro = bt.Cerebro() cerebro.addstrategy(SmaCross)

data0 = bt.feeds.YahooFinanceData(dataname='MSFT', fromdate=datetime(2011, 1, 1), todate=datetime(2012, 12, 31)) cerebro.adddata(data0)

cerebro.run() cerebro.plot()

Including a full featured chart. Give it a try! This is included in the samples as sigsmacross/sigsmacross2.py. Along it is sigsmacross.py which can be parametrized from the command line.

Features:

Live Trading and backtesting platform written in Python.

• Live Data Feed and Trading with

  • Interactive Brokers (needs ibapi and benefits greatly from an installed pytz)
  • Visual Chart (needs a fork of comtypes until a pull request is integrated in the release and benefits from pytz)
  • Oanda (needs oandapy) (REST API Only - v20 did not support streaming when implemented)

• Data feeds from csv/files, online sources or from pandas and blaze

• Filters for datas, like breaking a daily bar into chunks to simulate intraday or working with Renko bricks

• Multiple data feeds and multiple strategies supported

• Multiple timeframes at once

• Integrated Resampling and Replaying

• Step by Step backtesting or at once (except in the evaluation of the Strategy)

• Integrated battery of indicators

• TA-Lib indicator support (needs python ta-lib / check the docs)

• Easy development of custom indicators

• Analyzers (for example: TimeReturn, Sharpe Ratio, SQN) and pyfolio integration (deprecated)

• Flexible definition of commission schemes

• Integrated broker simulation with Market, Close, Limit, Stop, StopLimit, StopTrail, StopTrailLimitand OCO orders, bracket order, slippage, volume filling strategies and continuous cash adjustmet for future-like instruments

• Sizers for automated staking

• Cheat-on-Close and Cheat-on-Open modes

• Schedulers

• Trading Calendars

• Plotting (requires matplotlib)

From pypi:

• pip install backtrader

• pip install backtrader[plotting]

  If matplotlib is not installed and you wish to do some plotting

.. note:: The minimum matplotlib version is 1.4.1

An example for IB Data Feeds/Trading:

• Please install the ibapi package separately https://interactivebrokers.github.io/

For other functionalities like: Visual Chart, Oanda, TA-Lib, check the dependencies in the documentation.

From source:

• Place the backtrader directory found in the sources inside your project

Version numbering

X.Y.Z.I

• X: Major version number. Should stay stable unless something big is changed like an overhaul to use numpy
• Y: Minor version number. To be changed upon adding a complete new feature or (god forbids) an incompatible API change.
• Z: Revision version number. To be changed for documentation updates, small changes, small bug fixes
• I: Number of Indicators already built into the platform
