WIP: I will update this demo occasionally for new functionality. This demo program is to use gdax python client to access one's own gdax account to get account balance and setup frequent short-term order.
# First to install gdax python client package
pip install gdax- setup gdax API with certain permissions. here
- paste generarted API key, secret, and passphrase to the code.
- You are good to go.
Disclaimer: Please revise your code before placing any order. I am not responsible for any financial loss because of the usage of the code.
