1. Gentle and moderate volume. This refers to a situation where the trading volume of a single stock, after a sustained downturn in the early stages, suddenly exhibits a continuous and moderate increase in volume pattern similar to a "mountain shape". This form of mass production is called a 'pile of quantities'. The phenomenon of a "volume pile" at the bottom of a stock generally indicates that strong funds are intervening. But this does not mean that investors can immediately intervene. Generally, after a mild increase in volume at the bottom of a stock, the stock price will rise with the volume, and when the volume shrinks, the stock price will adjust appropriately. There is no fixed time pattern for such adjustments, ranging from a few days to several months. Therefore, investors must buy on dips in batches and have enough patience to wait when the reasons supporting buying have not been proven wrong. It should be noted that when the stock price moderately increases in volume, its adjustment range should not be lower than the low point in the early stage of volume increase, because if the adjustment falls below the cost zone of the main force's position building, it at least indicates that the market's selling pressure is still high, and there is a greater possibility of future market adjustment. 2. Suddenly release a huge amount. The analysis and judgment of this trend should be approached in several different situations. Generally speaking, releasing a large amount during an uptrend usually indicates that the forces of multiple parties have been exhausted, and it will be difficult for the market to continue rising in the future. The huge amount during the decline is usually the last concentrated release of bearish forces, and the possibility of further deep declines in the future is very small. A short-term rebound may be right in front of us. Another situation is to go against the trend and increase trading volume, which has a very noticeable effect when the market is full of bearish calls. These types of stocks often have a market trend of only one or two days, and then accelerate their decline, trapping many investors who followed up on the day of the volume surge. Distinguish trading volume patterns Technical analysis can be said to be an analysis of the three major factors of price, trading volume, and time, and trading volume analysis has great reference value. Although trading volume is relatively easy to falsify, it is still one of the most objective and direct market factors. 1. Reduce quantity. Shrinking volume refers to the extremely light trading volume in the market, and most people strongly agree with the later trend of the market. There are two situations here: one is to underestimate the future market, resulting in only people selling and no one buying; The second is to have a positive outlook on the future market, with only people buying and no one selling. Shrinking usually occurs in the middle of a trend. When encountering a decline and reducing volume, one should firmly exit the market, shrink to a certain extent, and then buy again when they start to increase volume and attack. When encountering an increase or decrease in volume, you can firmly buy and sell when the stock price is weak and there is a huge release. 2. Volume up. Volume increase usually occurs at the turning point of market trends, where various market forces gradually widen their differences on the future market. Some people are throwing away their assets, while others are absorbing them with large sums of money. Compared to reducing trading volume, increasing trading volume has a significant false element. It is very simple for the controlling main force to use their chips to strike and release huge trading volume. However, we do not need to give up because of choking. As long as we analyze the main force's intention, we can take advantage of it and "bite him big". 3. Pile quantity. When the main force intends to rise, they often make the trading volume very attractive. Over the past few days or weeks, the trading volume has slowly increased, and the stock price has slowly risen. The trading volume has formed a pile like shape on the recent K-line chart, and the more beautiful the pile, the more likely it is to generate a large market trend. On the contrary, the high pile volume indicates that the main force no longer wants to play and is shipping in large quantities. In this situation, we must resolutely withdraw and not fantasize about obtaining huge profits again. 4. Magnification and reduction of irregularity in quantity. This situation is usually caused by a demonic market without sudden positive news or basic stability of the market. When the situation is calm, it suddenly releases a historical huge volume, and then returns to calmness. Generally, weak market makers are attracting market attention in order to sell. Anyway, trading volume is just one of the few factors that affect the market. The market is an organic whole that cannot be viewed separately. Only through comprehensive analysis and judgment can the results be most accurate.
