• Install cbpro library by: pip install cbpro

• In Coinbase Pro, create your trading API, replace the key, b64secret and passphrase in the code

• In Coinbase Pro, connect your bank account for USD fund deposit

• Uncomment this line: #print(auth_client.get_accounts()) , temporarily delete all code after this line, run the code to retrieve the account string for your bank account, replace the ‘bbbbbbb’ string in the code with the account string

• Run the code with command: python coinbase-dca.py 100 DOT
