Lately, when watching my positions, I suddenly felt a chill down my spine: many people think that liquidation is just "when the price hits, it happens instantly," but the gap in between is determined by the oracle feed price. If the feed is slow by half a beat, the market may have already plunged and then bounced back, and your margin might be treated by the system as "truly broken," leading to liquidation in those few minutes before you even realize... To put it plainly, it's not that you're slow at reading the chart, but that the on-chain price recognition is slow.

I now deliberately leave a thicker buffer, especially after opening an options leg, because the biggest fear is thinking there's a hedge when in fact the liquidation breaks the structure, leaving the remaining leg exposed and naked. Recently, the testnet incentives and points system have been quite popular; everyone is guessing whether the mainnet will issue tokens, but anyway, don’t push your leverage too high just to earn a few more trades. If the feed delay causes the points not to be received, your account could be wiped out first.

I consider simple things as traps: don’t believe in the saying "the farther the liquidation line, the safer it is."
