Have you ever experienced that moment: even though you haven't moved much, your position suddenly gets "liquidated"? Many times it's not really because you're slow on the trigger, but because the oracle feed price is lagging behind... With delay, the on-chain price still shows the past, and the liquidation threshold is based on the old price. You think you're still safe, but you're actually on the edge; even worse, when the price rebounds, there's no time to save you. By the time the price updates, it's a straight cut.

Recently, I've been looking at the "yield stacking" of re-staking and shared security, which is basically all based on a bunch of assumptions: the price needs to be accurate, updates need to be timely, and liquidations need to be smooth. But once the feed price gets stuck, the higher the leverage, the more it resembles a domino effect when things go wrong. Anyway, when I deal with liquidation-prone assets now, I first check the oracle update frequency and anomaly handling, rather than just focusing on APY, because you really can't withstand that sudden hit.
