I just got annoyed with myself again... I wanted to quickly swap some coins, saw the pool looked okay, so I clicked directly, but I didn't keep an eye on the slippage, and I overestimated the depth. The moment I executed the trade, I was immediately "bitten." Even more foolishly, I split the order into two parts, pushing the price up with the first, and the second was like pulling a rickshaw for myself, messing up the rhythm entirely. When I review the trade, there's an ugly line of fees plus spread added inside and outside, and no matter how diligent I am with bookkeeping, this wave can't be saved.

Honestly, in trading, don't just look at the "expected proceeds," you need to treat the depth as real friction: if the volume is large, split it up; once split, it will be slower to execute. Better to wait two more blocks than to rush all at once. Recently, everyone has been talking about AI agents for automatic trading and interaction, but I see many hype stories, and few who truly focus on safety... No matter how smart the bot is, you first need to set clear rules for slippage, authorization, routing, and other underlying parameters, or it will just help you make mistakes faster. Anyway, I’ve lowered the default slippage first, preferring failed trades over paying more tuition fees.
