Last night, I rushed in at the last second to open a perpetual position again, and almost got taken out by a "fake price"… Later, after reviewing, I realized it was a delay in the oracle price feed, with the exchange price jumping first, and your position's margin being calculated based on the feed price. The liquidation line then becomes particularly awkward: the market moves instantly, but the feed price hasn't caught up yet. When it finally does, liquidation might be triggered with a "snap." To put it simply, it's not that you made a wrong judgment, but a time lag that traps you.

Recently, I also heard about some regions imposing additional taxes and tightening compliance, leading to tighter expectations for deposits and withdrawals. Volatility and slippage are more likely to be amplified, and the probability of hitting this delay has increased accordingly…
Now I only dare to lower my leverage further, preferring to earn less rather than getting wiped out by the feed price.
