The second type: the investor's direction is reversed. For example, an investor operates a rising contract, but the contract starts to fall the next second after buying. In this case, the futures will lose money as soon as they are bought. In this case, investors should wait patiently for a few minutes. If the contract price does not break through, they can continue to hold it. If the contract shows signs of being broken, they can make the opposite contract or sell it directly.
