Last night, I made a bad trade, there's nothing much to say except that I was careless. Seeing the order book looked okay, I rushed in at market price, but in that instant, the depth was ridiculously thin, and the slippage completely wiped out my expectations. I tried to fix it later by clicking twice, which meant chasing the trade at worse prices... the rhythm was all messed up.

Looking back, it’s actually very simple: this kind of liquidity pool that appears and disappears intermittently, don’t bet on “I feel it will succeed,” first check the ratio of order volume to depth, place a few orders gradually to eat through it, or just set an acceptable limit price—if you miss it, so be it. Now Layer 2 is always noisy about TPS, fees, and subsidies, but when it comes to trading, the real pain in your account comes from matching, depth, and slippage. That’s all for now, I won’t get itchy today.
