In the past, whenever I heard “data availability / ordering / finality,” my head would go blank. Later, after steeping tea and staring at the chart for a long time, I found that it’s enough to grab a single main thread: whether the trades and candlesticks you see are truly the kind of certainty that “everyone can verify, account for in the same order, and nothing will go wrong at the end.” Put simply, whether the data can be replayed by others, whether ordering can be jumped the queue by someone, and whether finality has to wait a long time before you dare to take it seriously—those three things, in the end, will show up in depth, bid-ask spreads, and how your orders are actually treated.

Recently, I’ve also been using ETF capital flows and the risk appetite of US stocks to explain everything. I do read it too, but I don’t fully trust it. What I care more about is this: when liquidity suddenly thins out, which chain/layer’s “certainty” is the one falling apart… For now, that’s all.
