Just now I was again stupid myself: I wanted to pick up a rebound at the bottom, but I opened the slippage too wide, the depth was thin, and I quickly ate through several levels. Seeing the transaction price made my mentality crash. Basically, I was quick with my hands but slow with my brain, thinking "I'll just buy a little, no problem," but the order placement got chaotic, and the more anxious I was, the easier I chased the execution.

Now I can only admit in retrospect: first check if the pool / order book is thick enough, if not, split the orders and slowly execute, don’t be greedy and set too large a slippage; if you really want to rush, wait for the slow transaction to settle before adding more. Recently, everyone’s been complaining about validators eating MEV and unfair ordering, I don’t have the right to criticize too much either—anyway, I’m just a retail trader, and when I get anxious, I end up giving others easy meat… For now, that’s it. I’ll have some coffee, calm down, and talk later.
