1: Your first SigTech strategy

Start Research
1. Start the research environment
Click the Research tab and, accepting the default settings, start the research environment
2. Create a new notebook
Click the "Python" button to open a new notebook.
Hint: Read our overview of JupyterLab if you've not used it before.
An equity investment strategy in four code blocks
In your new notebook, run the following code blocks:
1. Set up environment
# Import necessary libraries
import sigtech.framework as sig
import datetime as dtm
​
# Initalise the environment
sig.init();
2. Choose the instrument
The object name 1000045.SINGLE_STOCK.TRADABLE refers to the Apple Computers stock listed on the NASDAQ. You can find other financial instruments in the SigTech platform's Data section (see below).
my_stock = sig.obj.get("1000045.SINGLE_STOCK.TRADABLE")
3. Define the strategy
my_rs = sig.ReinvestmentStrategy(
    # The instrument to be used in this strategy
    underlyer=my_stock.name,
​
    # Define the historical period to run the strategy in   
    start_date=dtm.date(2018, 1, 1),
    end_date=dtm.date(2021, 12, 31),
    
    # Use the currency corresponding to this instrument
    currency=my_stock.currency,
    
    # Set the initial cash to be invested
    initial_cash = 1000,
)
ReinvestmentStrategy is one of SigTech's building blocks—shortcuts for rapidly creating and customising common strategies. Building blocks can be combined into a more complex strategies composed of multiple sub-strategies.
4. Run the strategy and view its performance

Your turn: customise the strategy
Make sure you understand SigTech basics by customising this strategy:
1. Choose a different instrument
The example above uses an Apple instrument. Browse SigTech's Data to find another  equity instrument and try building a strategy with that instead.
i. Find an equity instrument you're interested in:
APPLE INCO. | NASDAQ(COMPOSITE) | USD
ii. Click VIEW DETAILS to obtain the correct object name for referring to it in code:
"1000045.SINGLE_STOCK.TRADABLE"
2. Use a different historical period
Try running the strategy over a different historical period by changing the start_date and end_date.
3. Append ? to view docstrings
Run the following code to view the docstring corresponding to the instrument you're using in this strategy:
my_stock?
Run the following code to view the docstring corresponding to the RollingFutureStrategy building block:
sig.ReinvestmentStrategy?
Tip: add .? to any object to get its docstring. Docstrings are part of our API reference and are aimed at advanced users. Don't worry if much of it is unclear to you right now.
