Lately, everyone has been arguing loudly about "on-chain data," but what you're seeing might also be delayed. Nodes can lag behind, RPCs might be connected to congested public endpoints, and indexers still need to finish scanning events, import them into the database, and then generate a nice chart for you... Refreshing just to see the "market reacts immediately" is basically self-deception. Thinking about it later, it's quite funny. Especially during extreme funding rate periods, everyone in the group was guessing whether it was a reversal or continued bubble squeezing, but that "whale entering or exiting" tip you saw might just be someone’s operation from half an hour ago that you’re only noticing now. My approach is pretty simple: before key actions, check two more sources, switch to a different RPC, and if the data doesn’t match, don’t act yet. Better to miss out than get misled by delays.
