The so-called upside line is what we call a five-day moving average. Some friends think it's ridiculous. Do you need to talk about the five-day moving average? This fool also knows. Actually, this is the problem. The simpler it is, the less effort you will make to study it. It should be emphasized here that these specific terms generally refer to the daily line system, but the attack line can also be used for time-sharing, weekly line, monthly line and even annual line. If you are a mid-line shareholder, the five-week line is your attack line, and so on. The attack line has three functions. Turning the head of the attack line upward means that it helps to rise. The flattening of the attack line means that the unit is doing platform consolidation, and turning its head down means helping to fall. Readers should pay attention to the fact that when the market system is relatively stable, we should choose stocks with steep attack lines, which have large slopes, rise quickly and make money quickly. Trading line is a commonly used moving average 10, which has three trends: upward, flat and downward. You can refer to the attack line above to understand the specific meaning. It should be emphasized that the trading line is an important indicator of the band market. Once the trading line of individual stocks becomes steep and powerful, it is necessary to follow up decisively when making decisions. If the angle of the trading line is too large on the way down, you must be afraid and avoid risks in time. Once the trend line turns down, we must resolutely clear the position, leave the lifeline (referring to the 30-day moving average), turn straight up, the band market is optimistic, and follow up boldly: the decision line, which is what we usually call the 60-day moving average, is different from the lifeline mentioned last time. Lifeline is the basis of the strength of stock price band, and decision line means the strength of stock price trend, which is similar to trend line, but the response is more sensitive than trend line. All the main players and bookmakers attach great importance to the decision line. Once the decision-making line is reversed, basically all the main players have the courage to hold heavy positions. However, if the decision-making line is broken, traders will generally choose to leave unconditionally for security reasons. Therefore, for retail friends, we should attach great importance to the guiding significance of the decision-making line in the shareholding strategy, and at least keep our own direction choice consistent with the main force. Although the decision line can also be used in time-sharing, weekly and monthly systems, it generally refers to the daily line unless otherwise emphasized.
