PyCharm IDE
|
||||
~~~~~~~~~~~
|
||||
|
||||
PyCharm is an Integrated Development Environment (IDE) used in computer
|
||||
programming, specifically for the Python language. It streamlines the continuos
|
||||
development of Python code, and among other things includes a debugger that
|
||||
comes in handy to see the inner workings of Catalyst, and your trading
|
||||
algorithms.
|
||||
|
||||
Install
|
||||
^^^^^^^
|
||||
Install PyCharm from their `Website <https://www.jetbrains.com/pycharm/download/>`__.
|
||||
There is a free and open-source **Community** version.
|
||||
|
||||
Setup
|
||||
^^^^^
|
||||
|
||||
1. When creating a new project in PyCharm, right under you specify the Location,
|
||||
click on **Project Interpreter** to display a drop down menu
|
||||
|
||||
2. Select **Existing interpreter**, click the gear box right next to it and
|
||||
select 'add local'. Depending on your installation, select either
|
||||
"*Virtual Environemnt*" or "*Conda Environment" and click the '...' button to
|
||||
navigate to your catalyst env and select the Python binary file:
|
||||
``bin/python`` for Linux/MacOS installations or 'python.exe' for Windows
|
||||
installs (for example: 'C:\\Users\\user\\Anaconda2\\envs\\catalyst\\python.exe').
|
||||
Select OK. You may want to click on *Make available to all projects* for your
|
||||
future reference. Click OK again, and create your new environment using the
|
||||
set up of your virtual environment.
|
||||
|
||||
Alternatively, if you already have your project created, in Windows do:
|
||||
|
||||
1. File -> Default Settings -> Project Interpreter. Click the gear box next to
|
||||
the project interpreter and select ‘add local’, and follow the steps from the
|
||||
second step above.
|
||||
|
||||
On MacOS:
|
||||
|
||||
1. PyCharm -> Preferences -> Settings -> Project:’NAME_OF_PROJECT’ ->
|
||||
Project Interpreter. Click the gear box next to the project interpreter
|
||||
and select ‘add local’, and follow the steps from the second step above.
|
||||
|
||||
You should now be able to run your project/scripts in PyCharm.

Catalyst currently supports three different modes in which you can execute your

||||
trading algorithm. The first is backtesting, which is covered extensively in the
|
||||
tutorial, and uses historical data to run your algorithm. There is no
|
||||
trading algorithm. The first is **backtesting**, which is covered extensively in

that you should test any new algorithm.
|

|

Once you are confident with the simulations that you have obtained with your
|
||||
algorithm in backtesting, you may switch to live trading, where you have two
|
||||
different modes:
|
||||
* *Paper Trading*: The simulated algorithm runs in real time, and fetches
|
||||
pricing data in real time from the exchange, but the orders never reach the
|
||||
exchange, and are instead kept within Catalyst and simulated. No real currency
|
||||
is bought or sold. Think of it as a `backtesting happening in real time`.
|
||||
* *Live Trading*: This is the proper live trading mode in which an algorithm
|
||||
runs in real time, fetching pricing data from live exchanges and placing orders
|
||||
against the exchange. Real currency is transacted on the exchange driven by the
|
||||
algorithm.
