One of the important functions of the daily K-line chart is to predict the market trend and find the main resistance points. In addition, under normal circumstances, when the opening price is very low and the closing price is close to the highest price of the whole day, that is, a big sunny line is pulled out that day, which is a buying signal; The closing price is the same as the opening price, and the cross star appears on the same day, which is a signal that the market is waiting and there may be a turning point; However, the opening price was low, and the price rose and then fell back to the closing price below the opening price. On the same day, a negative line with a long upper shadow line was opened, which was an obvious downward signal.

It should be noted that these signals must be combined with other analysis methods to achieve higher accuracy. In a big rally, there are often some small declines, which usually last for a week or so. Only by studying the daily K-line chart and weekly K-line chart regularly can we not be confused by the short-term trend. Pay attention to follow up decisively when the trend is just forming. Many deep oil investors often make the mistake of following up too fast when the market falls, always thinking that the price has bottomed out, so they keep buying against the trend and occasionally seize the rebound opportunity to make a little money, but if they seize the wrong entry point or fail to make a profit in time, they will be trapped. The longer they delay, the greater the loss.

The weekly K-line chart and the monthly K-line chart are certainly not only for long-term investors' reference. The function of weekly K-line chart is not only to reveal the general trend, but also to reveal the cyclical law of the rise and fall of deep oil prices. Under normal circumstances, if the position of weekly K-line chart is in a rising cycle, the last weekly K-line chart will close at a high point, and this week's price will break through the highest point of last week, which are all signs of rising. The position of weekly K-line chart in deep fuel cycle is very important in judging the big turning point of market trend.
