Just educated myself again: clearly it's not a big order, yet I still got slippage and got wrecked. To put it simply, I was excitedly watching the candlestick chart, chasing after movements, but that pool's depth was as thin as paper. I threw in a big order all at once, and the execution price looked like a rainbow window light being pulled away, scattering and never coming back...

My past self always thought "just set a high slippage limit," but now I realize that the order placement rhythm is even more critical: first place a small order to test the waters, see the actual transaction and depth changes, then gradually add more. Otherwise, you're just giving others a gift. By the way, I also thought about the recent chain game inflation + studio spiral, which is actually quite similar: when liquidity is thin, everyone squeezes in, and the price ends up stepping on itself. Anyway, I’ve now engraved "Don't rush, first observe the pool" into my mind.
