It's just disgusting, why is the profit-taking so precise, no slippage?

$ETH Customer service here based on your order information, I see that you have set a stop-loss order which will be triggered as a 【Market Order】 by 【Mark Price】. I see that your set stop-loss price is 3700, but the execution price of your order will be 3672. The reason is that the execution price will be based on the 【Latest Price】. The price difference is 28 points, is this reasonable everyone?
