It’s useless for Binance to set a stop loss, it will directly give you a liquidation

The stop loss was set during the limit order, but it was not triggered when the stop loss point was reached, and the position was directly liquidated. It was too pitiful. When I asked the customer service customer service, they said that the stop loss was set too close, and the loss of 15% of the total amount was stopped. Are you saying it's too close? Stop loss is stop loss. Who is counting on this？
