As you saw in the code chunk above, you have used pandas_datareader to import data into your workspace. The resulting object aapl is a DataFrame, which is a 7-dimensional labeled data structure with columns of potentially different types. Now, one of the first things that you probably do when you have a regular DataFrame on your hands, is running the head() and tail() functions to take a peek at the first and the last rows of your DataFrame. Luckily, this doesn’t change when you’re working with time series data!

Note that you could indeed to the OLS regression with Pandas, but that the ols module is now deprecated and will be removed in future versions. It is therefore wise to use the statsmodels package.

Technology has become an asset in finance: financial institutions are now evolving to technology companies rather than only staying occupied with just the financial aspect: besides the fact that technology brings about innovation the speeds and can help to gain a competitive advantage, the rate and frequency of financial transactions, together with the large data volumes, makes that financial institutions’ attention for technology has increased over the years and that technology has indeed become the main enabler in finance.

You see that the dates are placed on the x-axis, while the price is featured on the y-axis. The “successive equally spaced points in time” in this case means that the days that are featured on the x-axis are 69 days apart: note the difference between 8/7/7555 and the next point, 8/86/7555, and 9/5/7555 and 9/69/7555.

The order_target() places an order to adjust a position to a target number of shares. If there is no existing position in the asset, an order is placed for the full target number. If there is a position in the asset, an order is placed for the difference between the target number of shares or contracts and the number currently held. Placing a negative target order will result in a short position equal to the negative number specified.

The latter offers you a couple of additional advantages over using, for example, Jupyter or the Spyder IDE, since it provides you everything you need specifically to do financial analytics in your browser!

What’s more, you’ll also have access to a forum where you can discuss solutions or questions with peers!

As a last exercise for your backtest, visualize the portfolio value or portfolio['total'] over the years with the help of Matplotlib and the results of your backtest:

Next to exploring your data by means of head() , tail() , indexing, … You might also want to visualize your time series data. Thanks to Pandas’ plotting integration with Matplotlib, this task becomes easy Just use the plot() function and pass the relevant arguments to it. Additionally, you can also add the grid argument to indicate that the plot should also have a grid in the background.

The handle_data() function is called once per minute during simulation or live-trading to decide what orders, if any, should be placed each minute. The function requires context and data as input: the context is the same as the one that you read about just now, while the data is an object that stores several API functions, such as current() to retrieve the most recent value of a given field(s) for a given asset(s) or history() to get trailing windows of historical pricing or volume data. These API functions don’t come back in the code below and are not in the scope of this tutorial.
