Futures backhand refers to the investor's reverse trading of the same contract, that is, if a long position was previously established, a short position is now established for the same contract, or if a short position was previously established, a long position is now established for the same contract. This operation is also called closing backhand or changing hands.

Futures backhand trading can be used to reduce or transfer the market risk of existing positions, or to make profits by taking advantage of market price fluctuations. For example, suppose an investor bought a long contract of 1 in the crude oil futures market before, and now he thinks that the market has shown signs of reversal. He can choose to close the long position and establish a 1 short position on the same contract in order to profit from the market decline. Similarly, if an investor previously established a short position of 1 in the silver futures market, and now he thinks that the market will rise in the opposite direction, he can choose to close the short position and establish a long position of 1 in the same contract in order to profit from the market rise.

Futures backhand operation requires investors to have certain market analysis ability and risk management ability, because the wrong backhand operation may bring greater losses. Investors should formulate reasonable trading strategies and strictly implement risk control measures according to market conditions and personal investment objectives.
