These past few days, after reviewing the liquidation orders, I remembered the issue of oracle price feeds... Usually everyone focuses on K-line charts, but when something really goes wrong, it's often because the "quote was half a beat late." When the price feed is delayed, your position has actually been broken through by the market, but the protocol still calculates health based on the old price. When the update finally comes, it's like a backstab: suddenly changing from "still able to hold" to "immediately liquidated," with no window left to add margin. To put it simply, it's not that you guessed the wrong direction; it's that you bet on the system's update timing.

Recently, RWA, U.S. Treasury yields, and on-chain yield products have been compared, and I also feel a bit tempted, but the more "stable-looking" the returns seem, the more I worry about the underlying liquidation mechanisms or price feed details being overlooked... Anyway, now when I open leverage, I check the oracle update frequency and data sources, and leave a larger margin. Next time, I might just set earlier stop-losses or reduce leverage—how would you prevent falling into this trap of delayed price feeds?
