Just now, my phone popped up with a bunch of red dots. I thought it was a snapshot alert, but it turned out to be a notification that my swap failed and was retried... Basically, it was my own careless mistake. I set the slippage to be "safe," but the pool depth was actually very shallow. I also chose to place the order during those few minutes when everyone was rushing to buy, and as soon as the quote jumped, I chased after it. The rhythm was chaotic, and I ended up paying fees twice for nothing.

Looking back, larger slippage doesn't necessarily mean more stability. When the depth isn't enough, no matter how much you set, it’s like gambling against yourself. Also, don’t let FOMO control your order timing; it’s better to split into smaller orders and wait a bit. Recently, people have been complaining about MEV and unfair ordering, which isn’t without reason. As a retail trader manually clicking, I often feel like I’m being "cut in line"... Anyway, from now on, I’ll check the depth first before acting, and don’t panic just because of red dots.
