It is said that speculation in foreign exchange can be traded in both directions, and buying up and buying down can make money. So how do foreign exchange buy up and down? First of all, we should analyze the market situation, judge the rising and falling direction of foreign exchange asset prices according to the bullish and bearish situation of the market, and then make technical analysis by using technical indicators, so as to get more profits by doing both. Of course, foreign exchange trading also has great investment risks. Once the price rises and falls in the wrong direction, it will suffer huge losses and even break out. However, in the field of foreign exchange trading, as long as investors don't have to trade all the principal, they won't explode. Because when investors trade in foreign exchange, the losses are fixed, and how much money they use for trading will only lead to losses, and the remaining principal can continue to trade and easily return to the capital.
