Take OKEX as an example:
Step 1: click "authorization" on the right of the corresponding exchange.
Step 2: go to OKEX's official website, click "account center", and find the "API management page" to create and copy the API Key and API secret inside. (to enhance security, it is recommended that you bind our IP: 188.8.131.52)
Step 3: enter Api Key and Api secret for authorization.
