The long-legged crossing in futures means that the upper and lower shadow lines are long, and the distance between the highest or lowest price in the gold market and the closing price is greater than 3%. Although from the appearance, the long-legged cross star seems to be very similar to the ordinary cross star, with almost equal upper and lower shadow lines and evenly matched sides.

The huge amplitude of the long-legged cross shows that the market structure will change and the market trend will change, especially when the long-legged cross appears at high or low prices, which means that the reversal may happen at any time.

Long leg crossing is an important early warning signal, which indicates that the original trend will change. If it has a long upper shadow line or a long lower shadow line, it means that it is more likely to reverse. In addition, when the cross star does not often appear in the market, the sudden appearance of the long-legged cross star is more meaningful.
