3rd, Zero and Game
In the stock market, the rise or the drop of stock market could influence the value of the stock whether to rise or drop, for example the Japanese new date iron stock price falls from 800 Japanese Yen to 400 Japanese Yen, the value of this stock has been reduced to half. However, in the foreign exchange market, the value of a stock and a currency is being calculated differently, this is because the exchange rate is refers to the exchange ratio both countries currency, the exchange rate change will influence one kind of monetary value to reduce and at the same time another kind of monetary value increase. For instance in 22 years ago, 1 US dollar exchanges 360 Japanese Yen, at present, 1 US dollar exchanges 110 Japanese Yen, this explains the Japanese Yen currency value rise, but US dollar currency value drops, in the end the value will not reduce or increase. Therefore, some people described the foreign currency trading is "zero and the game", exactly said is the wealth shift.

In recent years, investment foreign exchange market fund has continuously increased, the exchange rate fluctuation expands day by day, urges the wealth shift to be larger, the daily trading volume of the global foreign exchange involves 150 billion US dollars, the rise or falls 1%, means that the 150 billion funds has been shifted. Although the foreign exchange rate change is very big, but, any kind of currency will not become waste paper, even if some kind of currency unceasingly falls, however, but generally it represents certain value, only if such currency has been abolished.
