Recently, limit orders for contract settlements have turned into market orders. Has anyone encountered this situation? Customer service explained that a limit order does not necessarily mean it will be filled as a hanging order. So I'm puzzled. If it's a market order, I could just place an order at the market price. Since I chose a limit order, I must want it to be filled as a hanging order. Turning it into a market order doesn't make sense. In the understanding of the vast majority, a limit order means a hanging order will be filled, right? Is the exchange recently lacking in transaction fees, or has the market depth decreased? #手续费
