Once the broker_connection handle is ready, it can be used to query the list containing all the financial instruments provided by the broker.
Getting ready
Make sure the broker_connection object is available in your Python namespace. Refer to the previous recipe in this chapter to set up this object.
How to do it…
We execute the following steps to complete this recipe:
- Display all the instruments:
>>> instruments = broker_connection.get_all_instruments()
>>> instruments
You will get an output similar to the following. The exact output may differ for you:

- Print the total number of instruments:
>>> print(f'Total instruments: {len(instruments)}')
We get the following output (your output may differ):
Total instruments: 64743
How it works…
The first step fetches all the available financial instruments using the get_all_instruments() method of broker_connection. This method returns a pandas.DataFrame object. This object is assigned to a new variable, instruments, which is shown in the output of step 1. This output may differ for you as new financial instruments are frequently added and existing ones expire regularly. The final step shows the total number of instruments provided by the broker.
