Hedging refers to trading the same commodity in the spot market and the futures market in the same amount but in the opposite direction, or avoiding the losses caused by future price changes by constructing different combinations. For example, in order to reduce the risk of falling crop prices at harvest, farmers sell future crops at a fixed price before harvest.

However, most futures are speculative, and the sales contract is the difference! I also do futures, and it is best to do futures: I rely on the advantage of extremely low commission to make money at a time when prices fluctuate. Even if the commission is low, I can't operate frequently. I will wait for an opportunity to move again, and catch 10, and the income will be nearly 2% (because all of this 10 points are turned into profits, and the commission can be ignored), but the stop loss should be strictly set, and I will manage the money on behalf of my customers.
