As we all know, the trend line is one of the most important analysis elements in foreign exchange transactions, so how should we analyze the trend line? How can I see the trend through the trend line? Let chase finance show you how the trend line is used in foreign exchange transactions, so as to better carry out our transactions. One of the application rules of the trend line: in the rising market, the price falls back to the vicinity of the rising trend line for support, and the gold price may reverse upward; In the falling market, the rebound of gold price near the downtrend line will be resisted, and the price of gold may fall again. That is to say, the support level will be formed near the contact point of the upward trend line, while the resistance level will be formed near the contact point of the downward trend line. Special attention should be paid to this rule of foreign exchange trading trend line in practical application: when the gold price contacts the trend line, investors should adopt a cautious operation strategy to avoid the unpredictable future trend of gold price. The second application rule of the trend line: if the downward trend line of the foreign exchange trading market is maintained for a long time, the price drops sharply, and the price adjustment breaks through the trend line, which is a signal that the downward trend begins to reverse. This law mainly has the following three characteristics: 1, and the downward trend line lasts for a long time; 2. The price of gold has fallen sharply; 3. When the price of gold breaks through the downtrend line, it generally presents a heavy volume state. In practical application, it should be noted that the confirmed reversal breakthrough point and downward trend line should not be too large. Generally, it cannot exceed 5%. Otherwise, the height and reliability of this breakthrough will be greatly reduced. The third application rule of the trend line: when the gold price breaks through the trend line, if the original trend line will become a support or a negative, the price will often rebound or fall back. There are three main features of this law that need our attention: 1, which is only applicable to the upward or downward trend; There is no guiding significance for the horizontal trend; 2. Only when the original trend line is confirmed as an effective breakthrough can this rule be applied; 3. The action nature of the original trend line will be reversed, that is, support will become resistance and resistance will become support. The fourth application rule of foreign exchange trading trend line: in the early stage of rising market, the slope of trend line is often large. When it falls below the original trend line, it usually rises along a more moderate trend line, and the original trend line will form resistance. When the price of gold falls below the second revised trend line, the market will reverse. The law also has the following three main characteristics: 1, and the gold price always runs along the new trend line; 2. The original trend line will form resistance; 3. When the second corrected trend line is effectively broken, the market will reverse. Above, we introduced the application rules of trend line in foreign exchange trading at four points.
