抄底信号

分屏封面：左半边血红色，K线暴跌，一位交易员抱头惊慌；右半边电光绿，同一根曲线触底反弹，同一个人此刻咧嘴大笑竖起大拇指。一道巨大的白色闪电把两边劈开。正中是超大堆叠标题「果断抄底」，黄字黑边，一支红色下跌箭头正变形成绿色上涨箭头。强烈、戏剧化、极具点击欲。

Split-screen thumbnail: left half blood-red with a plunging candlestick chart and a panicked trader clutching his head; right half electric-green with the same chart bouncing upward and the same man now grinning and giving a thumbs up. A giant white lightning bolt divides the two sides. Huge stacked text 'BUY THE DIP' in yellow with a black stroke sits center, a red down-arrow morphing into a green up-arrow. Intense, dramatic, click-worthy.
