Do you know how much the old duck head has increased after it is generally formed? What is the general increase of old duck head? Old duck head generally increases by more than 30% to 200%, which is mainly affected by many factors. In most cases, the increase of the old duck head in the stock market has a great relationship with the consolidation time in the early stage of the stock, the adjustment of the K-line shape, the density of the trading area, the position of the banker, the amount of funds of the banker and the market situation. These factors often affect the banker's operation, and then affect the stock price. In most cases, when the dealer began to collect chips, the stock price rose slowly, and the volume of the 5-day and 10 moving averages rose, forming a duck neck. Then, as its share price began to pick up, the high point of the share price formed a duck head.

After this operation, the shape of the old duck head is formed, so there are many factors that change during this time. 1 The longer the consolidation time of the old duck head, it will often lead to insufficient popularity, so that the banker lacks follow-up when he pulls up for the second time, and the increase is limited. 2 If the K-line shape is relatively stable, it will be easier for the dealer to pull up, but the trend of the K-line is extremely complicated, reflecting that the dealer level is extremely resistant to pulling up and the increase is limited. 3 The intensive trading area in the early stage of the old duck head often accumulates a large number of lock-up plates, which will cause selling pressure when they are pulled up. If the banker's strength is not strong, the increase of old duck's head is limited. The amount of money in the dealer's hand determines the height of the old duck head. The more chips, the higher the dealer must be, and there is room for shipment. The banker's funds are basically the same as those held. The banker's capital determines the strength of breaking through the consolidation zone and the final increase of the stock.
