The stock market is constantly changing, with the overall trend fluctuating up and down. Investors are facing a very complex market. Investors in this market are influenced by various factors when selecting stocks. Some factors are beneficial for investors to make investment decisions, while others can have a negative impact on their decisions. Many new investors, due to a lack of experience, are often confused and at a loss when facing such a complex market; Some veteran investors often cannot make correct judgments on the trend of the overall market.

How to use a time-sharing chart to analyze the overall market

The overall trend of the market is often volatile throughout the day, sometimes going strong in the morning and suddenly diving in the afternoon. But sometimes it falls heavily in the morning, but in the afternoon it can turn the tide. So if we can predict in advance whether the market will close negative or positive on that day? It is crucial for some investors to make T 0 or short-term stock purchases on the same day. The following is a highly accurate method of judgment.

（1） When the stock index opens short and opens high

(1) Within half an hour of the stock index jumping short and opening high, it has been running above the gap with a strong upward trend. If this situation occurs, the market should judge the closing as a bullish line for the day and can absorb it during the intraday correction.

(2) Within half an hour after the stock index jumps short and opens high, the stock index first falls to fill the gap and then rises. If the stock index is in an upward state at 10 o'clock, it should also be judged that the market is closing positive on the same day, but the accurate probability is not as high as the first type.

(3) If the stock index jumps short and opens high for half an hour, and the stock index continues to decline, and is in a downward state at 10 o'clock, it should be judged that the day is closing in the dark, and caution should be exercised on the day.

（2） When the stock index opens flat

(1) If the stock index continues to rise strongly within half an hour of opening, it should be judged that the market closed positive on the same day.

(2) If the stock index continues to decline within half an hour of opening, it should be judged that the market has closed in the dark on that day.

(3) If the stock index falls first and then rises within half an hour of opening, and if the stock index is in an upward state at 10 o'clock, it should be judged that the market is closing positive for the day.

(4) If the stock index rises first and then falls within half an hour of opening, and if the stock index is in a falling state at 10 o'clock, it should be judged that the market closed in the dark on that day.

（3） When the stock index opens lower

(1) If the stock index continues to decline within half an hour after opening low, it should be judged that the market has closed in the dark on that day, which has a higher accuracy and is prone to a sharp drop on that day.

(2) When the stock index opens low and immediately fills the gap within half an hour and continues to rise, the probability of closing positive for the day is high.

(3) When the stock index rebounds within half an hour after opening low, but the gap is not filled, and then falls again around 10 o'clock, it should be judged that the market closed in the dark on that day.

(4) When the stock index opens low and fills the gap within half an hour before falling, it should still be judged that the market has closed in the dark.

The above situations are all predictions, but the accuracy of the probability is high or low, and it does not necessarily mean it is correct. Below, we will talk about two special situations:

a. Sometimes within half an hour of the morning opening, the fluctuation range of the stock index is very small, often within one or two points, and the red and green bars are very short, sometimes intersecting with each other. If this situation occurs, the market is prone to a sharp rise and fall on the same day. Generally, there is a significant increase.

b. Sometimes, within half an hour after the opening of the market in the morning, if the stock index fluctuates greatly, showing a trend of ups and downs, it can be judged that the market has fluctuated significantly around the opening index on that day.
