核心逻辑
这是一个综合型技术指标，结合了均线系统、KDJ随机指标、资金流向分析、成本分布计算以及基本面财务评估。核心原理是：通过短期KDJ指标判断股价动量变化，结合资金流向指标（A8）识别主力资金进出，同时利用成本均线（COSTT）计算市场平均持仓成本，并通过大盘相对强度（DAPAN）判断个股与市场的关系。此外，还引入了财务指标（YAOGU、XJF、YZZ）评估股票的基本面质量和拉升潜力。
买卖信号
**买入信号**："小番茄买进"条件满足时买入，具体包括：(1) A8指标2日内最低值等于7日内最低值，且A8<0出现2次，然后A8上穿其2日均线；(2) 前一日DOWN线低于前两日DOWN值；(3) 今日UP线高于昨日DOWN值。满足条件后系统会在K线图上显示黄色"买"字和紫色K线。 **卖出信号**：无明确卖出条件语句，但包含资金状态显示（流入/流出加快或减慢）、主力行为（吸筹/洗盘/出货）、受大盘压制/拉动等辅助判断信息。
