What would you do if 519 happened again? Be prepared

1: There must be a large amount of U in the account, and be prepared to go over the bottom.

2: You must not hold more than 3 spot positions. It is best to buy two.

3: If you hold a contract order, you can only hold one order. Place the order to increase or decrease the position in advance.

4: You can take advantage of the trend to open a short position and buy spot for hedging.
