Just paid tuition again. After replaying it and reviewing, I realized that the order placement rhythm matters far more than I’d imagined. Plainly put, it’s a slippage plus depth problem. When I placed my order, I didn’t notice that the pool’s liquidity had already been chewed through by a large order. As a result, once my trade went in, it immediately jumped through several price tiers, and my cost ended up about 0.5% higher than expected. Later, when I checked the on-chain records, I found that during that period miners were aggressively抢ing MEV, and the sorter/ordering service also seems a bit偏. Retail orders basically got queued to the back and ended up eating higher slippage prices. No wonder I’ve been hearing people complain about ordering fairness lately—it really is pretty anxiety-inducing. You calculate your entry point perfectly, but you still get squeezed in the middle and repeatedly get rubbed. Anyway, next time I’ll learn my lesson: first look at the depth chart, then wait a few minutes for the big orders to digest, or just use limit orders to slowly work through it—don’t rush the entry.
