After you have selected to copy a user (Signal) you will have the option to add a Max Drawdown.
There are three levels to adjust in your Max Drawdown:
Firstly, you have your Warning Level. At this level, you will be sent a notification.
Secondly, you have your "Soft Stop Level", if this is triggered all copying will be suspended. No future copy trades will be placed on your account.
Finally, you have your "Hard stop level". If this is triggered, all of your copy trades will close and copying will be suspended.
