This vivid metaphor reveals the core of the "rat-handling" behavior.

Simply put, a liquidation of positions is not a simple loss, but an act of forced liquidation of positions by the trading platform in leveraged trading, due to the drastic changes in market prices, resulting in the investor's margin being insufficient to maintain the original contract. This process means that the investor invests all the principal (margin) lost.
