No matter how much expert someone is, but risk always remain there in every trade. That's why we should not put all money in one trade. For me the best thing is to divide your port folio in at least 5 currencies/stocks. So that if you get the loss in 2 trades still you will recover in 3 of them. Don't Always follow the experts and the trends but obviously take advise from the experts. Watch the higher buying trends.. because if the buyers are on a stock that means there are better chances of increase in price as the demands goes up.
