Like any form of trading, copy trading carries a degree of risk that should be closely managed according to your individual circumstances, goals and overall strategy.
Since every trader has a different approach to risk, it is the responsibility of the individual to manage risk appropriately. To help manage risk when copy trading, you should carefully consider the past performance of any traders you choose to copy, be aware of their approach to risk, and, if necessary, adjust individual trade settings before you begin automatically copying trades.
As with other forms of trading, you should only invest what you can afford to lose. It is also important to remember that you can stop copy trading at any time.
