Recently, while reviewing position closures and liquidation records, I was once again educated by the oracle's "price feed delay." To put it simply, the price you see has already changed, but the contract still holds the quote from a few seconds ago, and the position is like using old accounts for risk control... When the market moves suddenly, you think it's still safe, but the next update skips your buffer zone, and the liquidation line is broken through with a single kick.

On-chain, I specifically monitored a certain update: a source with a price feed interval of about 12 seconds, where an address 0x8f…a2 added margin during those seconds but couldn't recover, and when the oracle refreshed, the liquidation bots rushed in, executing at a worse price than what was displayed on their interface at that moment.

Now, we're talking about interest rate cut expectations, the US dollar index, and risk assets jumping up and down together. This kind of macro sentiment-driven "instantaneous volatility" actually depends more on the oracle's rhythm. Anyway, my own approach is to be honest: keep leverage lower, don't keep the liquidation line too close, and when you see sharp fluctuations, treat it as system delay. Better to earn a little less than to fight against time lag.
