If the market does not reach the preset price, the final execution price may vary depending on the currently available market price. When a position is closed due to take profit and the execution price is better than the preset price, it is called positive slippage; if the execution price is worse than the preset price, it is called negative slippage. Similarly, when a position is closed due to stop loss, if the execution price is better than the preset price, it is considered positive slippage; if the execution price is worse than the preset price, it is considered negative slippage.
