Copy trading to me is not too advisable to do because those you're copying their trades will have to win before you can also win and when they lose, you also have the same effect on your account, which i doubt its something we should value to that extent because of the risk involved, most of the traders that opted in for this are the newbies in trading, they cant afford to risk losing money at their own negligence or inexperience in trading, but instead go to the professionals for trading.
