Low Cross Star: Also known as "Morning Star", if it appears at the end of the market decline, it means that the stock price may have bottomed out, and the probability of a recent stock price rebound is relatively high.
High cross star: also known as "Twilight Star", that is, after a round of stock price rise, both long and short sides play a game, but obviously many parties start to exert their strength, so it is a signal to peak, and the probability of a decline in the market outlook is greater.
Appear on the way up: usually because of the fierce contest between long and short sides, it means that the upward trend has not changed and many parties have begun to take a break. Conservative investors can watch the cross star appear in the last few trading days to decide whether to buy.
