This morning, the traffic at the intersection was jammed again, and my coffee in hand had gone cold...

The feeling when looking at the chart is similar: you think pressing send is the end, but actually there's more behind it—"who helps you cut in line."

Recently, someone asked how much blockchain builders and retail traders need to understand about bundles.
I think there's no need to turn yourself into a researcher; just be sufficient: knowing that a swap or pending order might not be added to the block in "chronological order," and could be bundled together and inserted;
when there's sharp volatility, price slippage, transaction order, or even what you see on-chain as "who comes first or second," might differ from your expectations.
To put it simply, it's more like high-speed lane changing—smart drivers will find gaps, ordinary cars shouldn't force their way.

As for on-chain data tools and label systems like "who's buying and who's selling," I now treat them as a mood thermometer—whether lagging or easily misled, they can easily cause emotional trading.
My approach is simple: small trial orders + limit slippage + avoid chasing those one or two needle-shaped waves, and leave the rest to discipline.
Let's stick with this for now.
