During rush hour on the subway, I got a little impatient and made a trade, only to be thoroughly educated: I looked at the quote that seemed pretty stable, and I was still thinking "with just this much slippage, what’s there to fear," but the moment I clicked, the depth felt like it was being pulled away from me, and the execution price immediately jumped to a range I didn’t recognize. To put it plainly, it’s not that the market was against me, but that I was too confident in my order pacing... When the pool isn’t deep enough, stepping on the gas causes the car to slide sideways.

Looking back, there are just two things: first, don’t treat slippage as decoration; setting too wide = writing a blank check for yourself. Second, don’t go all in at once; split it into a few parts, wait a second or two to observe the matching/market depth changes, which is more like “negotiating with the market.” By the way, I want to complain that the rumors about stablecoin regulation, reserve audits, and de-pegging in the group are cycling again. When everyone gets anxious, they love chasing prices even more. I even get nervous just watching my fingers... Anyway, I’ve decided to remove the “urgency” from my trading, at least for today.
