Last night I paid my tuition again: seeing whales on the chain moving in the same direction, I hesitated and followed, but the slippage was large, and the pool depth was shallow, so the transaction price was directly "more expensive than I thought"... To put it simply, I placed my order too hastily, didn't do batch trading, and was too lazy to wait for limit orders, rushing in and getting market-educated. Now I give myself a "patch": first check the depth and the last few trades before acting, split the entry into two or three parts, and prefer smaller slippage even if it's slower. Recently, the new L1/L2 incentives to boost TVL have been quite noisy, everyone rushing in while complaining "mining, selling," so I’ll post a cat picture to calm down first—anyway, don’t let emotions take over as a trader.
