Today I realized during my review that sometimes I don't lose to the direction, but to the "time lag." Oracles feeding prices slowly, that kind of half-beat delay—when the market suddenly gets volatile, you think you're still safe, but the next update directly pushes you from the healthy zone to the liquidation line, and you can't even reach in to add margin. Basically: the price you're watching isn't the price used for liquidation, and the bigger this gap, the more it torments you.

Now when I open leverage, I make sure to check the feed frequency/data sources—don't think it's a hassle; when something really goes wrong, you can only blame yourself for pretending to be asleep. By the way, I recently thought about the NFT royalty disputes that have been flying around—some say they want creator income, others say they want liquidity... Anyway, the ones most likely to be "optimized" first are usually ordinary people. For now, I’ll just keep gradually removing these small pitfalls from my habits.
