I just reviewed that failed order from last night. Honestly, it’s not that I was wrong about the direction; I was just too confident... Even though the market looked fine, once I hit the next level of depth, it collapsed, and the slippage directly ate away at my profits. Plus, my order placement was a bit slow—by the time I clicked confirm, the market had already switched to a different script.

I used to blame "latency" a lot, but this time it feels more like I was treating "being able to execute" as "being able to execute at the price I want." From now on, I’ll stick to the clumsy method: first use small orders to probe the depth, feed in several times, even if it costs a bit more in fees, rather than trying to fight the depth all at once. Recently, everyone’s been talking about modularization and the DeFi layer, developers are excited, but as a user, I just want to ask: can I at least lose less to slippage... Anyway, I’ll keep paying my tuition fees for now.
