Last night I was startled by my own emotions again: even though it looked like the price didn't move much, my position almost got liquidated.

Later, after checking the on-chain records, I found out it was the oracle feeding prices slowly by half a beat, and when it finally updated, it directly compressed the fluctuations of the "real world" into a single spike...
You might think you can still add margin, but in reality, your available time window has been stolen.

To put it simply, liquidation isn't just based on the price at the moment you open the app, but on the "momentum" it was fed into the contract.
When price feeding is delayed, even low leverage can be mistakenly liquidated, let alone high leverage.
Recently, everyone has been criticizing validators' income, MEV, and unfair ordering, and I also resonate: paying more Gas doesn't necessarily make you safer, it might just let you see yourself being lifted out faster.

My current self-rescue strategy is: keep my position smaller, leave a thicker buffer, and when it’s critical, I’d rather run first than gamble on "price update" timing.
Anyway, I have big mood swings, so I first pull myself back from the edge of liquidation before reviewing.
