In the futures contract, the asset price falls, and the reduction mechanism is no longer started. Adjusting the futures reduction ratio to zero means that in a specific futures contract, when the underlying asset price falls to a certain extent, the reduction mechanism will no longer be started. The futures market will set a certain reduction ratio. When the price of the underlying assets falls below this ratio, measures will be taken to reduce the holdings to protect investors from excessive losses. However, when the reduction ratio is adjusted to zero, it means that even if the price of the underlying asset falls to any extent, the reduction mechanism will not be started, and investors need to bear all risks and losses.
