I just reviewed last night's failed order, and it's really not about the wrong direction, I was just too impatient. Seeing that the mempool was still relatively clean, I threw it in all at once, but the actual depth was a bit thinner than I thought, and the slippage parameters were set with too much confidence. I got stuck in the middle, unable to go up or down, and in the end, the transaction price was significantly worse than I expected... To put it simply: when liquidity is insufficient, trying to be quick just means paying tuition fees.

Now I will split it into smaller parts first, check the transaction returns and pending changes every few seconds, then decide whether to add more; also, don't be too superstitious about those on-chain data tools or label systems. Recently, someone was complaining about lag or even being misled, and I've also encountered "seemingly stable" labels that suddenly give you reverse slippage. That's it for now, I'm going to sleep, and tomorrow I'll keep an eye on the weather forecast.
