These past few days I've been looking at liquidation cases, and the more I look, the more I feel that oracle price feeding is quite "boring but deadly." You think you're still a bit away from the liquidation line, but if the price feed is delayed, the on-chain spot price disconnects from the real outside price, and the liquidation bot acts on what it sees, liquidating you first. To put it simply, it's not that you calculated incorrectly, but that you bet on "it will update in time."

Recently, some places are also changing their tax/regulation trends, with deposit and withdrawal expectations tightening and loosening, causing people's emotions to suddenly tip in one direction, and the volatility becomes even sharper. The lag of a few seconds or minutes in the price feed is exaggerated... People tend to get liquidated passively when they least want to move.

I'm feeling pretty cautious now: the less leverage, the better, leave some buffer, and don't run the liquidation line right at the feed price. Moving slowly is pretty depressing, but at least it's not the kind of depression caused by system education. That's all for now.
