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

Note

The minimum matplotlib version is 1.4.1

For IB Trading:

• IbPy doesn't seem to be in PyPi. Do either:

  pip install git+https://github.com/blampe/IbPy.git
  

  or (if git is not available in your system):

  pip install https://github.com/blampe/IbPy/archive/master.zip
  

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

Alternatives

If after seeing the docs (see also the example below) you feel this is not your cup of tea, you can always have a look at similar Python platforms:

• prophet

• quant

• AlephNull

• Trading with Python

• visualize-wealth

• tia: Toolkit for integration and analysis

• QuantSoftware Toolkit

• bt

  bt slightly pre-dates backtrader and has a completely different approach but it is funny bt was also chose as the abbreviation for backtrader during imports and that some of the methods have the same naming (obvious naming anyhow): "run, plot ..."
