Holding a loss in the futures market is a state when an investor maintains a position that is losing, hoping the price will reverse to recover capital or make a profit. This is a risky strategy, as futures use high leverage, causing losses to potentially escalate quickly. Long-term loss holding can not only cause psychological pressure but can also lead to a margin call if the account is not sufficient to maintain the position. Therefore, investors need to have discipline and establish clear stop-loss points to manage risk effectively.
