Before each margin trading, we should make a reasonable analysis and judgment on the trend. This is one of the most important factors to ensure the success of investment. Among the specific technical analysis methods, morphological vibration analysis is one of them. The form of vibration analysis of margin financing and securities lending comes from RSI index. As we all know, rsi indicator is a very practical technical analysis method to judge the market and decide to buy or sell when it is consolidating at a high level or sideways at a low level. But in practical application, we find that this form often fails. 1, high reversal * * * has a high success rate: if the exchange rate of margin trading goes out of some important reversal patterns such as head-shoulder, M-head and triple-top, and the RSI indicator also forms the same pattern at a high position (above 50), it means that the upward momentum of the exchange rate has been exhausted, and there may be a long-term reversal in the market outlook, so investors should sell it in time. The extent and process of exchange rate decline can be judged by referring to the top reversal patterns such as head and shoulder top, M top or triple top. 2. When the exchange rate of margin trading fluctuates at a low level, it is also a good opportunity to buy. The specific operation is as follows: When the RSI curve turns to the bottom of W or the bottom of triple bottom at a low level (below 50), it means that the downward momentum of the exchange rate is weakened, and the exchange rate may build a medium-and long-term bottom, so investors can open positions in batches on dips. If the trend curve of the exchange rate shows the same pattern continuously, it can be confirmed. The rising range and process of the stock price can be judged by referring to the bottom reversal patterns such as W bottom or triple bottom. Application Tip: Generally speaking, when the exchange rate pattern and rsi index fluctuate, the success rate is higher at the top and lower at the bottom. However, on the whole, the form * * vibration analysis method of RSI index in margin trading analysis has higher overall judgment accuracy, especially for the volatile foreign exchange market. The specific analysis methods of margin trading should be applied to specific markets, and RSI indicators may be more suitable for the volatile foreign exchange market. But in other cases, the market may need another way of analysis, so investors should analyze it according to different market conditions.
