Last night, I made a big mistake, and it’s really not that I misread the market direction, but that I was just too quick: I saw that the depth in the pool was as thin as paper, and I still insisted on market orders, and when the slippage got large, the transaction price was directly "educated." After reviewing, there are only three things: first, check the depth (don't just look at the surface trading volume), then tighten the slippage, and prefer to place limit orders and split them into several parts; second, don’t fight the candlestick pattern with your order timing—being too rushed makes it easier to feed liquidity to others. Recently, AI Agents and automated trading have been hyped up quite a bit, but honestly, being able to press a button doesn’t mean they can handle slippage and MEV for you, so on-chain interaction security really requires your own close attention.
