Recently, cross-DEX small arbitrage has become more obvious: you think you're watching "real-time on the chain," but often it's just RPCs, nodes, and indexers queuing up to feed you messages... I see that the price difference in a certain pool still exists on my side, but switch to a different RPC and it's gone immediately. It's not that the market is changing instantly; it's that the on-chain data on your screen is delayed. On the macro side, they're talking about interest rate cut expectations, the US dollar index, and risk assets acting up together. When everything moves in sync, everyone gets more anxious, and the more anxious you are, the easier it is to fall into the trap of the "delayed truth."
