It feels like you think you're "viewing real-time on-chain data," but in reality, you're often looking at a version that others have relayed, and it's not unusual to be a few seconds to tens of seconds behind. The reason is quite simple: the nodes/RPC you're connected to might already be queuing, rate-limiting, or even serving cached data; plus, indexers need to scan blocks, process logs, and build databases, which are not part of the consensus layer. If they go offline and rescan, you'll see the "on-chain suddenly change its tune." To put it plainly, the candlestick/trade flow you're watching might be a beat or two behind the actual mempool/block production. Recently, with memes and celebrities shouting out, attention shifts so quickly that newcomers get excited and rush in to catch the last wave, but they're still using slow RPCs to see "what just happened," while others have already moved on... Now I at least check two different RPCs/browsers to compare, so I don't mistake latency for market movement.
