Just paid my tuition again: I hesitated and entered the market, set the slippage too loose, and ended up getting caught in a "depth of air" trade, with the execution price significantly worse than I expected... Honestly, it’s not a chain glitch, it’s just that I was too rushed with my order timing. Now looking back, I realize that when the depth is thin, using market orders is more like giving money away to others, especially when the funding rate is extreme. During the times when the group was arguing about reversals or continuing to squeeze the bubble, volatility loved to strike unexpectedly. As a beginner, I always thought "slippage is just part of the fee, so opening bigger is easier"; now I understand that slippage is the maximum you're willing to pay emotionally. If you really want to enter, split the orders, wait for a retracement, or just place limit orders on L2 and slowly eat the fill, instead of stubbornly risking mainnet gas fees like a fool. That’s it for now, anyway I admit defeat this time.
