Lunchtime fishing around, I wanted to shift some positions on a certain L2, but I placed the order too hastily, didn't check the slippage carefully, and didn't understand the pool depth either. After the trade, I saw it was less than expected... Basically, I mistook "can execute" for "can execute at the price I want."

Looking back: for this kind of liquidity, don't try to do it all at once; split it into two or three trades, wait for block confirmation, which is actually more stable. Also, don't try to snatch during sudden market jumps; the more you rush, the easier you are to get caught in slippage.

Recently, hardware wallets have been out of stock everywhere, and phishing links are rampant. I feel I need to be reminded: don't rush to click, don't rush to sign, don't rush to place orders. Anyway, I’ve re-saved all my frequently used websites, and I’ll try small test trades first... Lunchtime is only so long, don’t turn yourself into someone paying tuition for others.
