First thing you need to do is create the API Keys on BitMEX first.
Log into your BitMEX Account: https://www.bitmex.com/
Go to "Account" in the upper menu bar and then select "API Keys" under "Account & Preferences".
Next enter a label for your key, & select "Order" in "Key Permissions".
Then enter your 2FA code, if required, and click on the "Create API Key" button.
Now that your API Keys have been generated, we can move forward to setting up your account in HyperTrader.
