Last night I paid my tuition again... I originally wanted to take a small position and go for a quick move, but I was impatient and didn't "pause" for a moment, placing a market order directly. When slippage magnified, I got a harsh lesson: watching the price jump up and down, the average transaction price was much worse than I had expected. To be honest, it's not that my strategy is poor, but that the rhythm was too rushed—first stop, place a limit order, split it into several smaller trades and take it slow. Sometimes that's actually more stable; then pause and observe whether the order book is thick or thin, don't just focus on candlesticks; finally, stop refreshing, don't get caught up in others talking about "modularization/DA layer" and feel like you need to get excited too. Honestly, I was just confused... Anyway, the takeaway from this review is: if you can wait, just wait. Don't treat patience as a decoration.
