There is a special shape called "cross star" in the common daily K-line chart. The cross star is actually a candle chart with opening price and closing price, and the upper and lower shadow lines are very long. Under normal circumstances, the cross star appears at the inflection point of the price trend, which usually gives a relatively obvious buying and selling signal. The cross star is one of the most commonly used technical analysis indicators for short-term and mid-line traders.

Cross stars are more common in the trend after the price fluctuates greatly. In the stock market, the cross star usually appears when the stock price reaches the technical support level or resistance level. When the price moves from one direction to another, the cross star will appear in it. If the cross star appears at a low price and its shape is relatively complete, it is generally considered to be a good time to buy. On the contrary, if the cross star appears with high price and complete shape, it is generally considered as a good time to sell.

The cross star has a special shape and cannot be simply classified by rising or falling. When using the cross star, it needs to be used together with other indicators. For example, MACD indicator, moving average, etc. You also need to pay attention to the time and location of your appearance. For short-term and mid-line traders, crossing is more important. It is one of the important basis for them to judge whether to enter the market or enter liquidation. In practice, it is necessary to gradually accumulate experience in order to make better use of the cross star as a technical analysis index.
