Grid strategy is an investment strategy, which can help investors to trade in the stock and futures markets. The basic idea of grid strategy is to divide the account funds into multiple shares, buy a unit fund every time the stock price falls to a certain extent, and then sell it when it rebounds to a certain extent, constantly buying low and selling high, throwing high and sucking low. When the stock price fluctuates within a certain range, this will be very effective because it can continue to make profits.

The advantage of grid strategy is that it can be used as a supplement to long-term investment strategy, avoiding idle funds and improving the efficiency of capital use. In a volatile market, profits can be achieved even if the prices of trading varieties fluctuate back and forth, avoiding the phenomenon of "riding a roller coaster" in investment income.

However, it should be noted that the grid strategy is not applicable to all varieties. Only varieties that fluctuate constantly and fluctuate up and down are suitable for making grids.
