* * * shock is a very common phenomenon in foreign exchange transactions. In Gann's theory, when there is a multiple relationship between the internal fluctuation frequency of the market and the driving force frequency of the external market, the market will have a * * vibration relationship, which will cause the market to move up or down. This theory has been further demonstrated in foreign exchange transactions. When you open the chart of foreign exchange market, you can find that the market trend often fluctuates greatly. Once it breaks through the low position, the exchange rate is like a runaway wild horse flying upward; Once it breaks down from a high level, the exchange rate is like a river that breaks its banks. This is a graphic reflection of the shock effect of the foreign exchange market. In the foreign exchange trading market, there are four main factors that cause market shock, and speculators should be aware of them. 1, fundamental vibration: that is, through economic data, interest rate level, major political and economic events, etc. It is concluded that a certain currency will rise or fall, and put it into the market for verification on this basis. If the market is verified in the right direction, then the current trend will be supported by fundamental vibration and the original judgment can be adhered to. 2. Multi-period vibration: We judge by the coordinated vibration of multi-period technical system, that is, the trend, shape and index with price as the core. When long-term investors, medium-term investors and short-term investors buy or sell in the same direction at the same time, there will be upward or downward vibration in power; When the long period, the middle period and the short period in the time period meet at the same time and in the same direction, it will produce an upward or downward vibration in time; When the long-term moving average, the medium-term moving average and the short-term moving average meet at the same price and have the same aspects, it will produce upward or downward * * * vibration in cost; When K-line system, moving average system, KDJ indicator, MACD indicator, RSI indicator and other technical indicators all send out buy or sell signals, it will produce technical multi-cycle vibration. 3. Multi-currency * * * vibration: By cross-judging multi-currency * * vibration, we can find the currency with the strongest trend, so we can capture the trend of international mainstream funds, then this currency is the strong focus of the current foreign exchange market, and what we want to do should be the variety that international mainstream funds pay attention to, so that the income is both safe and guaranteed. 4.* * Vibration of foreign exchange trading market: With the global economic integration, there will be a horizontal linkage effect between currencies in various markets. We can greatly improve the accuracy of analysis and judgment through the coordinated vibration of multiple markets. For example, if we want to analyze the US dollar, we should also pay attention to the relevant market trends, and see how Dow Jones and NSDAQ go, how gold prices go (seesaw effect), crude oil trends, bond markets, futures markets, interbank lending rates and so on. Through multi-markets, we can verify whether the trend of the US dollar conforms to our judgment. This greatly improves the reliability. It can be said with certainty that if all the above four aspects support the rise of a certain currency and all of them oscillate in coordination, the rising probability of the currency can almost reach 100%, and if one of them is not coordinated, the appreciation probability will be reduced. This is the main method to measure risk. As can be seen from the above analysis, the occurrence of * * * vibration is conditional. Meet these conditions, you can produce vibration; When the conditions are not met, * * vibration will not occur; When certain conditions are met, it will also produce * * * vibration, but the impact is small; When the conditions of * * * vibration are met, the greater the power of * * * vibration. * * * Vibration is a resultant force, which occurs simultaneously and pushes in the same direction.
