It means buying low and selling high. When the stock price is lower than the purchase price, it can be sold when the stock price becomes higher. The operating skills of low suction and high sale are as follows:

1, the bottom of the region where the stock price has reached the maximum decline in the process of fluctuation will naturally form a central region where investors can take action.

2. In the day, you can also suck low and throw high, also called T, which is a position established in the case of bargain hunting. For example, if an investor buys 500 shares and the stock price falls the next day, but it is in a fluctuation range, then he can make up his position when it falls and sell 500 shares when the stock price rises, thus earning the difference between buying low and selling high.

What's the difference between low suction and high throw and high throw and low suction?

The difference between low selling and high selling lies in the different order of buying and selling. Selling low and selling high means buying first and then selling, while selling high and selling low means selling first and then buying. Which one to use depends on the trend of the stock.
